how to make an alternator into a generator
This will allow the generator to work for several hours without running the engine. The type you want to use for this project should be an older design such as you might find in a scrap yard.

An AC car alternator is a very good ac generator in the automobile its output is rectified by diodes to become DC.
. Attach the alternator to bracket. Add the battery to your device. If your alternator has a negative terminal you will see the signidentifier F Field or Neg.
Running The First Wire Find the chassis ground or the negative. In the example shown I was attempting to convert an induction motor into a generator thats something that is outlined in the booklet alternator secrets. Single wire connection type with the regulator.
How To Wire An Alternator To Make A Generator Making The Battery Connections. The generator project will require a vertical shaft gas engine from a lawn mower. Now instead of going with the fixed tail design we decided to built a furling tail that will prevent the generator from overspeeding.
Place the bolt and tighten. Single wire connection type alternators include internal regulators. Then when you want to use it as ac generator the diodes must be removed then the stator windings connected to a step up transformer 12 volts to 110 or 220volts.
If you have an alternator and you want to use it as a DC generator you just need to connect the output leads to a rectifier block a full wave bridge rectifier for a single phase alternator or a three phase bridge rectifier for a three phase alternator. Most of these engines have either 3 or 4 bolts holding them down to the existing lawn mower base. Its our first time converting a car alternator into something thats more useful for us one so we should call it sucess.
Attach cables to positive and negative terminals on the alternator. This type of alternator does not contain a regulator inside. Arrange the motor so the shaft is parallel to.
Connect the alternator bracket to base. Eventually you can easily wire them into the house breaker box directly. The good thing is that witht the prop on the alternator achieved almost the same speed.
You need to charge it up. The frame is built arround the alternator followed by a bearing holder that will allow to point the generator into the wind direction. It could spin faster which made it capable of generating current even at low RPMs.
How to Use a Car Alternator to Make a Generator Step 1. Step 1 - Choose the Right Alternator. And finally you have to go back to the battery bank.
Step 3 - Bolt the Alternator. Instructions Attach the motor to your base. DC power must be fed into the rotor to create a field magnet.
Place horizontal shaft lawnmower on top of the same plywood sheet. The design of the generator may need different pulleys on the engine to apply proper shaft speed to the generator head and the alternator or this may be workable with 1 engine pulley and 1 belt. Connect the battery cables to the positive and negative terminals of the alternator.
And in return the battery bank will supply the required 12v input for your 110v inverter. How to Turn a Car Alternator into a Generator External Voltage Regulator Type Alternator. Mount alternator to 12-inch plywood sheet with 14-inch steel lag bolts.
Running the wires from the alternator to the battery is also very simple. Though both convert mechanical energy into electrical energy an alternator then creates AC electrical energy while a generator can convert the power to both AC and DC energy. Start with the 12v generator which is constructed with an automotive alternator.
Install both motors one as a motor and other one as a generator on wooden piece tightly by metal strip and tight the screws. Battery cables from donor car can be used Add the battery to the device and attach the positive and negative cables to the appropriate terminals on the battery. AC generator head 3600 RPM.
Pulley similar to shown. The battery should have the same signs. This makes the generator a bit more versatile since it can power.
Compared to the gasoline engine this thing offered instant power which is a great feature of electric power. GM alternator 12 volt or 24 volt. When you compare the current output of an alternator vs generator there is a noticeable difference.
The motor on the left is a one hoarse power motor which turns at 3450 rpm. Step 2 - Connect the Alternator. Step 4 - Power it With Green Sources.
Run the belt over the pulleys and make sure that they are taught. Arrange the motor so the shaft is parallel to. Connect the device to a 12-volt battery to provide stability in the system.
How to Use a Car Alternator to Make a Generator Step 1. Slotting the mounting holes of the engine will provide good adjustment to achieve this. The smaller lighter field windings could be put on the armature.
The typical lawn mower engine will be 3 to 5 horse power and will have a 78 shaft with a 316 key way and a threaded hole in the bottom of the shaft. Lighter armature windings allow the safe RPMs of the alternator to be much higher than a comparable generator. Attach the positive and negative.
A smaller pulley could be put on the alternator.
