Alternator conversion and alternator change. A relatively modern alternator only needs two wires to do its job. Any questions i can try to answer.If your interested in the same set up I am affiliated with Amazon. A welder needs high currents at low voltage, a power system high voltages and low currents. To answer the first part of the question you need to understand how a generator, and an alternator each make electricity. Rod T. Great video, I learned a lot and want to switch my 62 MGA to an alternator. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. The inside of the propeller wheel will rotate, and this can be used to turn an alternator's pulley by welding a suitable automotive pulley to the wheel's surface, then driving the alternator with a belt. 1 decade ago. Try that with a gasoline or diesel generator. 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 … 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. These batteries could then be used to power an inverter, which would produce the AC voltage needed to run the house. 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 How Alternators Work to Make Electricity . One doesn’t make “better” electricity than the other. 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. With over 25 years in high-tech industrial and aircraft power system development, put our know-how to work for your innovative projects. Frankly, I was a bit surprised reading that high voltage, I was expecting not more than 15-20VAC. Classic Car Automotive Electrical Systems - Part 2: How Generators and Alternators Work GENERATORS AND ALTERNATORS. Attach the alternator to the propeller assembly. In a vehicle, an alternator is used to charge the battery. Alternators usually use internal regulators. Alternator conversion and alternator change. No matter how good your battery-powered saw or drill is, sometimes you need a plug-in tool to get the job done. However, once a load is applied (i.e. Sep 8, 2019 - how to use a car alternator to make a generator - Google Search Step 5 Drill holes for mounting the lawnmower motor to the plywood with a 1/4-inch bit. Alternators usually have internal voltage regulators. 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. A smaller pulley could be put on the alternator. The windings on the armature (the part that rotates) are the current generating windings. Drill holes in your fan blades, and use bolts to attach the fan blades to the rotor. Slotting the mounting holes of the engine will provide good adjustment to achieve this. 3 Generators use external regulators. You say it is a commercial vehicle so it should have one, or at least an option to fit one. A welding generator/alternator is wound differently from a power generator/alternator. An automobile alternator is essentially an AC generator. They also have another shortcoming. We offer a kit to convert your MGA to an alternator. 3 Generators use external regulators. LarryT. It needs a small wire that goes to the light on the dash, and it needs a heavier wire that carries the current out of the alternator and to the rest of the car. 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. We make this observation not to criticize their quality or even their applicability as wind generators. It always has fresh gas and starts easily. It always has fresh gas and starts easily. That’s how the electricity is directed out of the generator and to the rest of the car. DEMO This calls for additional regular maintenance. 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. January 7, 2014 @ 5:13 pm If wires are reused, use the GEN to A wire to connect to alternator (usually a heavier gauge wire). 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. A car is easier to move than a 150 lb generator. My next step is to follow your suggestions and get out there and make the change! 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. A Car Alternator Can Be Made Into A Powerful Hybrid Brushless Motor In A Couple Hours With Common Tools. How can I use a car alternator to effciently generate electricity? Generators are heavy, and often large. An alternator was a logical evolutionary step. As such, once it begins to produce electricity, it can keep itself moving without any additional work. 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. Also, running all that current through the bars at the end of the armature and through the brushes is tough on the brushes. The bicycle wheel is linked to the alternator with a belt turning the alternator shaft freely. The steps needed to prepare an alternator as a three-phase generator and as a three-phase motor are the same. Now, build a generator with a lawn mower engine! The link is here 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. We make this observation not to criticize their quality or even their applicability as wind generators. An alternator can be easily acquired; making construction of a small wind turbine generator a perfect choice. 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. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. Who knew? What’s the difference between a generator and an alternator? I will try to explain those differences without making your head hurt...to much. (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.). You can use car alternators to power a home. TWO THINGS. It could spin faster which made it capable of generating current even at low RPM’s. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. I noticed that the battery in the diagram was positive ground too. If you are the kind of classic car owner that likes to blend the classic with the improved, this may be something you’ve thought about. The first cars used generators, but this was changed to an alternator because these are more efficient. This provides a reliable and low-cost alternative to high-power brushless motors for many applications which is easily acquired and second-sourced. Generators had external voltage regulators. 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 … Existing circuitry to charge the car if you need to understand how a generator ) be negative ( )!
