As it turns out, re-purposed car alternators have become extremely popular and relatively cost-effective for use in small wind generators. If you use a large car alternator, you may be able to do it, but a 220V alternator, no. The simplest solution, of course, is to use the car's own existing circuitry to charge the car battery. Any other DIY wind turbine info really welcome. A car's battery only provides enough power to operate the vehicle's starter when starting. It always has fresh gas and starts easily. I was wondering if some one… Trying to generate 5kW from the engine's belt driven alternator is not the right way to approach this. Our Alternator Conversion Manual, "How to Convert an Automotive Alternator to a Hybrid Brushless Motor" shows in clear step-by-step instructions with photographs how to do the conversion. Whilst the car is running, the alternator also supplies the battery, keeping it charged to supply power the vehicle when the engine is off again. What has to be changed? 736. Now we can go on to how that battery gets charged. SIMPLE. A breakthrough was an inexpensive electronic device called a diode, DEMO With diodes the stator windings could become the current generating windings. I have a car alternator that has 3 wires. An automotive alternator converted to a motor can exceed the performance of both brushed and conventional brushless motors because of the combination of its brushless drive current and adjustable field. Generate power for corded tools anywhere you go without the cost and hassle of a gas-powered generator by wiring a power inverter to your truck battery. 3 Generators use external regulators. As you learned in school, when you pass a magnet past a coil of wire, (or you pass a coil of wire past a magnet) you create electricity in the coil of wire. My next step is to follow your suggestions and get out there and make the change! First off the turbine would power the alternator. INSTALL I understand the difference (now:) between the car alternator and the alternator within the inverter generator. It has internal diodes to convert AC to DC. Ron King, Expand the vido to shhow what else has to be done if you have + ground. Some of us have given up our old generator and moved ahead to an alternator. Photo by Robert D. Copeland The 3-inch washer used to attach the fan and clutch assembly to the alternator. If you spin it fast enough, long enough, you can put the output through rectifying and regulating circuitry and use the output to charge up a battery. One doesn’t make “better” electricity than the other. I wouldn't had to initiate all this, simply would hook rectifier and use commercial 12/220 inverter. Saved by Glen Stanford. TWO THINGS. How Alternators Work to Make Electricity . John, Good video but the wiring diagram shown for the alternator has the battery connections the wrong way round. A little more digging and we discovered a few more truths, like a Delco alternator’s stator is wound to operate at very high RPM because it is designed to be operated by a powerful, relatively high RPM engine. stephen heaney. How Alternators Work to Make Electricity . If you are considering using this alternator to generate energy, try attaching it to a pole and mounting a blade type fan or propeller to the shaft. The colors of the wires are white, black, and yellow. It also explains how to drive the alternator as a motor. HOW TO CONVERT FROM GENERATOR TO ALTERNATOR. Important: Turn your car off, pop the hood, and connect the voltmeter’s positive probe to the positive terminal on the battery and the negative probe to the negative terminal on … The car alternator is also measured to determine its physical dimensions. A car alternator changed over to a motor can put out in excess of 1.0 HP -- in many applications far above that, depending on the alternator, how it's converted, and how it's controlled. March 15, 2013 @ 3:31 pm Slotting the mounting holes of the engine will provide good adjustment to achieve this. I will try to explain those differences without making your head hurt...to much. Car Alternator to Cheap Motor: Hi,This is my first instructables.Because of my English i put more pictures and less words.In this instructable i will try to explain how to convert car alternator to … Should ( as stated in video) be negative (-) earth, August 21, 2016 @ 12:41 pm Step 5 Drill holes for mounting the lawnmower motor to the plywood with a 1/4-inch bit. A relatively modern alternator only needs two wires to do its job. Run the wiring of the tachometer from the vehicle's interior to the engine compartment. This was encouraged by the increasing electrical power required for cars in this period, with increasing loads from larger headlamps, electric wipers, heated rear windows and other accessories. As such, once it begins to produce electricity, it can keep itself moving without any additional work. A car is easier to move than a 150 lb generator. When the battery initially powers the car, the alternator belt, or V-belt, spins the pulley on the alternator, causing the rotor inside the alternator to spin very quickly. We make this observation not to criticize their quality or even their applicability as wind generators. The smaller lighter field windings could be put on the armature. Classic Car Automotive Electrical Systems - Part 2: How Generators and Alternators Work GENERATORS AND ALTERNATORS. This generator was built using a 3 horse power Briggs and Stratton horizontal shaft motor, a GM 65 amp automotive alternator (with built in voltage regulator), a used car battery, a pulley and V-belt, a 12 volt cigarette lighter outlet box with fuse, a DC to AC power converter, a low voltage control switch, a scrap of 3/4" plywood, a few scraps of 2 x 4 lumber, 4 wheels, and two battery cables. Now, build a generator with a lawn mower engine! An alternator can be easily acquired; making construction of a small wind turbine generator a perfect choice. If wires are reused, use the GEN to A wire to connect to alternator (usually a heavier gauge wire). Try that with a gasoline or diesel generator. Who knew? Also, the relatively small amount of power needed so the field windings can become an electro-magnet, can be sent to the armature via a pair of small brushes that would ride on slip rings on the armature instead of bars. If wires are reused, use the GEN to A wire to connect to alternator (usually a heavier gauge wire). For Ron who wants more details for converting from + to – Ground – all Moss MGB Catalogs have a page in the back that explains this conversion quickly and easily. An alternator can be easily acquired; making construction of a small wind turbine generator a perfect choice. Favourite answer. The link is here January 8, 2014 @ 8:27 am To know what to do with the two wires. Place the lawnmower motor onto the plywood base again and fit a car alternator belt around the alternator pulley and the motor shaft pulley. The biggest differences are… Self Excite an Alternator Without Any DC Generator, Capacitor Bank or Battery: Hi!This instructable is for converting a field excited alternator into a self-excited one.The advantage of this trick is that you won't have to power the field of this alternator with a 12 volt battery but instead it … Before you test the alternator, you’ll need to make sure your car’s battery is fully charged. If you obtain two alternators, you may use one as a generator and the other as a motor. Just make sure you leave enough gas to actually drive the car if you need it. June 16, 2013 @ 11:28 am One method of doing this is to use the alternators to recharge storage batteries. Last month's article dealt with the principles of DC electricity and how your car's battery functions. Automobile alternators perform more duties than simply recharging a car's battery. Here is a quick project that will give you the ability to use an old, working alternator as an alternative source for energy. Some of us have moved from an old style alternator to a more modern and more efficient alternator. Drill holes in your fan blades, and use bolts to attach the fan blades to the rotor. In a classic generator, the stator windings (statue, stationary – fixed in place) affixed to the inside of the case serve as the field windings. © Copyright 2020 Moss Motors, Ltd.

Any questions i can try to answer.If your interested in the same set up I am affiliated with Amazon. The field wire has been removed / taped off and is no longer used. LarryT. The battery has pairs of lead plates immersed in a mixture of sulphuric acid and distilled water. This provides a reliable and low-cost alternative to high-power brushless motors for many applications which is easily acquired and second-sourced. This setup helps to simplify the needed calculations for this type of power system. All power drive current to this motor is brushless: drive current passes only through the stator and does not go through any brushes. China has effectively cornered the market on the key ingredient of brushless motors -- rare earth metals, which are used for the permanent magnets in a brushless motor (BLDC), so brushless motor prices keep increasing. http://www.mossmotors.com/Shop/ViewProducts.aspx?PlateIndexID=45271, July 23, 2015 @ 12:09 pm As it turns out, re-purposed car alternators have become extremely popular and relatively cost-effective for use in small wind generators. Whilst the car is running, the alternator also supplies the battery, keeping it charged to supply power the vehicle when the engine is off again. As you might remember, our first generator was built using a horizontal shaft engine. (battery cables from donor car can be used) How can I use a car alternator to effciently generate electricity? 7 Answers. This is called a Hybrid Brushless Motor since it has a combination of brushless power drive current and a small brushed field current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. May 28, 2013 @ 5:04 pm TWO THINGS. With the advent of more electrical accessories like power windows, the generator could not meet the additional demands and was replaced by the more powerful alternator. Minis built up to 1969 (i.e. Use sandpaper to smooth the holes. car alternator to operate as a low speed generator for wind or hydro power generation. Fundamental: That protects the generator from high RPM damage, but it leaves the generator almost valueless at low RPM’s. And alternators are readily available worldwide -- as close as the nearest auto parts store or junk yard. Lighter armature windings allow the safe RPM’s of the alternator to be much higher than a comparable generator. Slide the lawnmower to the side so the belt is tight. 2 The roles of the armature windings and the stator windings are reversed. The first cars used generators, but this was changed to an alternator because these are more efficient. Alternators usually have internal voltage regulators. Alternator Conversion Manual for Download...... Click here for Alternator Speed-Torque Curves, Speed-Power Curves, and Performance Data. Alternator conversion manual shows how to convert a car alternator into a high-power motor as a low-cost alternative to a high-power brushless motor. You can let an inverter sit for 5 years and it will still work when you turn it on. Deal Buster. Before you test the alternator, you’ll need to make sure your car’s battery is fully charged. In a classic generator, the stator windings (statue, stationary – fixed in place) affixed to the inside of the case serve as the field windings. Generator Wiring: Alternator Wiring: As you can see, the BAT post of the regulator is being used as a junction point for the battery connection to the new single wire alternator. Removing a generator and installing a alternator. A Delco car alternator is about the size of a cantaloupe fruit and so there is a limit of how much copper and magnets that can fit inside of it. Your car isn't a purpose-built portable generator, but in an emergency, it's not a bad stopgap measure at all. Anonymous. Generators had external voltage regulators. According the wiring diagram I thought it would be an easy job!! An automotive alternator can be converted into a powerful hybrid brushless motor, and can exceed the performance of conventional brushless motors (BLDC). However, once a load is applied (i.e. The bicycle wheel is linked to the alternator with a belt turning the alternator shaft freely. Making your own bicycle generator is a good addition for those who are interested in going off the grid and finding a way to live on their own terms. Having the current generating windings on the armature means there is a limit to how fast you could spin it without harming it. LarryT. A Delco car alternator is about the size of a cantaloupe fruit and so there is a limit of how much copper and magnets that can fit inside of it. Use for electric vehicles, robotics, industrial, alternative energy, experimental electric aircraft, and automotive applications. carlbergs, Rod, Some of us have given up our old generator and moved ahead to an alternator. Alternator converted to a motor driving a high-speed turbine water pump. Watch the video. Generators were used in automobiles until around 1970, when alternators became more practical (due to the availability of cheap, small diodes). To answer the first part of the question you need to understand how a generator, and an alternator each make electricity. Also, while most alternators have always had an internal voltage regulator, the older models often had more wires than a more modern alternator. You need to turn it at least fast enough for it to generate enough voltage to overcome the forward voltage drop of the diodes. (Since the Hybrid Brushless Motor functions the same as a conventional brushless motor, this manual is also a practical, no-nonsense way to learn how brushless motors work.). It always has fresh gas and starts easily. Alternators usually use internal regulators. In addition, a car alternator functioning as a motor has more versatile control than a conventional brushless motor, and it can have more power and torque at high speeds than a conventional brushless motor of similar size due to its adjustable field. A car is easier to move than a 150 lb generator. David Pethig, found video really good and instructive know how to convert to an alternator now thanks just one thing you said the vehicle had to be neg earth but on the diagram it shows the battery as pos earth is this right or MUST the battery be neg earthed thanks again will try it out on my Ford 100E, December 31, 2013 @ 5:32 pm An alternator converts the mechanical energy provided by a vehicle's engine into electrical energy. It is connected with relatively long wires to the generator or alternator. We can deal with two wires. The operation of the alternator, usually within a vehicle, is simple. Even old car generators must spin too fast to be practical for wind power, but there have been many good plans for modifying them. 3 Generators use external regulators. The generator used a spinning armature to generate DC electrical power and in practice was both rugged and reliable. RE: alternator as a generator in a car evelrod (Automotive) 20 Jan 03 14:36 birt, Since you seem to be having a great deal more difficulty than you should be, … The field wire has been removed / taped off and is no longer used. I really learned a lot about converting from my Lucas Generator with brushes and the RB340 Control Box to a modern Alternator and I found it’s an easy upgrade to do! The brushes last a very long time. An alternator was a logical evolutionary step. Using an automotive alternator to construct a wind-powered electrical generator can reduce or eliminate dependency on "grid" power, even if the wind turbine is only used for lighting or recharging batteries. See streaming videos below of converted car alternators driving a high-capacity water pump and a 2.8 Horsepower (HP) Dynamometer Load. Sep 8, 2019 - how to use a car alternator to make a generator - Google Search Use bolts to attach your rotor to your alternator. An old car alternator can provide one of those ways! The alternator is comprised of a voltage regulator and three main components: The stator, rotor, and diode. Building a wind generator -- outside of the electrical wiring, for which you should consult an experienced electrician -- is a fairly simple process. Installing an alternator in place of a generator, or upgrading an older style alternator to a more modern alternator, is usually not hard to do. Alternative Power Sources Alternative Energy Off The Grid Wind Power Solar Power Energy Projects Power Energy Energy Technology Renewable Energy. Only a small field current passes through brushes and smooth slip rings to the rotor. This is a highly reliable design with minimal abrasion (unlike commutators in conventional dc motors), which is typically used for resolvers and synchros on aircraft, and high-reliability industrial applications. Sometimes  the life of the car. The electricity used in a car is DC, yet we call this device an alternator. January 7, 2014 @ 5:13 pm Try that with a gasoline or diesel generator. The interesting part of this set-up is the use of a car alternator. Because of the difference in the way the electricity is produced, it makes better sense to use a more efficient, and more reliable, alternator and then convert the electricity back to DC. This field is adjusted by applying a small dc current, typically 0.5A – 4.0A. Perhaps more importantly, a car alternator was designed to be under the hood of a car. Generators are heavy, and often large. That means the alternator is a nice neat all-in-one package, but it leaves us with a number of wires and the old regulator that need to be dealt with. They both make the same kind of electricity. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Mount the tachometer above the steering column or on the dashboard of your vehicle using the supplied hardware and tools recommended by the manufacturer. You can use 1/2-inch galvanized pipe to make the generator bracket. A welding generator/alternator is wound differently from a power generator/alternator. ie positive (+) earth. Drill a 1/4-inch hole at about 7 1/2 inches from the front end of the steel tube through both sides of the tube. A Smart Aleck’s Guide to Buying a Spitfire, http://www.mossmotors.com/Shop/ViewProducts.aspx?PlateIndexID=45271. Fit an AC alternator (230 or 110 Vac) to the power take off on the vehicle's gearbox. In older cars (before about 1964) this was done with a generator. Perhaps more importantly, a car alternator was designed to be under the hood of a car. Let’s talk about wiring. The challenge for many of us is how to wire the upgrade. However, consider their usual use case: attached to a car engine that’s probably mostly running around 1000-4000 RPM via a belt that gives about 4x speed multiplier on the alternator. Place this assembly in … what is their purpose? At the end of the armature we have a series of conductive bars. Half of the plates are connected to each terminal . Locate the black wire and hook it up to the battery. Attach alternator bracket to base (be sure to properly align pulleys) Attach alternator to bracket, install belt and tighten; Attach cables to positive and negative terminals on the alternator. Fortunately, you can easily test your car’s alternator to see if it's working using a voltmeter, which is an instrument that measures voltage. The steps needed to prepare an alternator as a three-phase generator and as a three-phase motor are the same. Another advantage to this system is that it can easily be … Many of our visitors and customers have read our article discussing the homemade generator made from a horizontal shaft engine and a car alternator. the alternator is turned “ON” to generate electricity), the wind turbine isn’t strong enough to turn. You can use car alternators to power a home. The windings on the armature (the part that rotates) are the current generating windings. An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. Answer Save. For all generators and externally regulated alternators, the regulator is a small device mounted somewhere on the firewall or the inner fender of the car. Generator Wiring: Alternator Wiring: As you can see, the BAT post of the regulator is being used as a junction point for the battery connection to the new single wire alternator. 1 decade ago. But alternators use just a low-cost, powerful electromagnet, which is cheaper and more reliable than the rare earth permanent magnets used in brushless motors. A smaller pulley could be put on the alternator. Last month's article dealt with the principles of DC electricity and how your car's battery functions. In a vehicle, an alternator is used to charge the battery. An automotive alternator converted to a motor is much less expensive than a conventional brushless motor with the same power output. (Field, Current Generating) If we go from an old style alternator to a more modern one, we may be surprised to find some of the early alternators had external voltage regulators like generators did. A car alternator that can be readily converted to a powerful motor costs about $100.00, but a conventional brushless motor that produces about the same power output typically costs far more -- well over $500.00 and is often more difficult to obtain with long order lead times. I get asked quite often why the car companies switched from generators to alternators, and who did it first. Two wires isn’t intimidating at all. The alternator also has a pin at the bottem that says "Bat" so im guessing that goes to the negative terminal of the battery. The field windings (stationary) in the generator serve as an electro-magnet. To keep the RPM’s of the generator under control, generators were usually set up with a large pulley to lower their RPM’s. DO NOT TRY THIS AT HOME. DEMO This calls for additional regular maintenance. They also have another shortcoming. This can give better performance than a conventional brushless motor by producing full torque at BOTH low speeds and high speeds, compared to a conventional brushless motor which tends to lose torque at high speeds. You can let an inverter sit for 5 years and it will still work when you turn it on. An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. A Toyota car alternator taken from a junkyard is characterized via an Open-Circuit test to evaluate its operating specifications. Run the belt over the pulleys and make sure that they are taught. When the battery initially powers the car, the alternator belt, or V-belt, spins the pulley on the alternator, causing the rotor inside the alternator to spin very quickly. I use mine all the time and I like it better than any generator I've owned. The electromagnet is more reliable because it is not subject to demagnetization, and it does not have the risk of flying off the rotor at high speeds like rare earth permanent magnets used in BLDC motors. Until the 1960s, automobiles used DC dynamo generators with commutators.With the availability of affordable silicon diode rectifiers, alternators were used instead. Generators make DC current, and batteries need DC for charging. It not only generates electricity but also provides you with a great cardio workout, which could be an alternative to going for a run and a good addition to anyone’s life.
