Can you convert an alternator to a motor?
The humble automotive alternator hides an interesting secret. Known as the part that converts power from internal combustion into the electricity needed to run everything else, they can also themselves be used as an electric motor.
How powerful is an alternator motor?
A car alternator can put out more than 1.0 HP if it’s changed over to a motor, depending on how it’s converted, and how it’s controlled. A conversion of an automotive alternator to a motor is less expensive than a conventional motor.
How fast does a car alternator need to spin to produce power?
An alternator has a normal range of operation. Most alternators need to spin at about 2,400 rpm at idle, have their maximum output above 6,000 rpm, and should never exceed 18,000 rpm.
How much HP does an alternator motor make?
An alternator takes about 1 HP for every 25 Amps of power. At full output, a 100 Amp alternator will need about 4 HP. For a long time, most alternators don’t operate at full output.
How do you convert an alternator to a DC motor?
Connect the shaft of the DC motor to the shaft of the alternator. Connect the electrical output of the alternator to whatever you want to power. Connect the DC electrical motor to a source of DC power. The motor will turn the alternator and the alternator will generate AC power.
Can you use an alternator for a wind turbine?
Windmills can provide you with electrical power for free – but to convert motion into current you’ll need a generator. “A car alternator could be a handy solution if you’re stuck, producing a steady 12 volts as its spindle is turned,” says Dartnell.
What is the minimum RPM of a 12V car alternator?
What is the minimum RPM of a 12V alternator? The minimum RPM of a 12 volts alternator is nearly 1800 RPM. The exact value of the RPM depends upon the specifications of the alternator. A normal car idles at 750 RPM whereas a sports car idles at 1250 RPM.
Does it matter which direction an alternator spins?
The spinning makes three-phase alternating current that will be the same no matter which way it’s spinning. The diode pack (six diodes) turn it into direct current. The polarity will be correct as well. An alternator doesn’t care which way it turns to charge.
Does an alternator charge at idle?
Assuming the alternator, engine, belt, and battery are all in working order, then yes, a car battery will charge when idling. The only caveat is that it doesn’t really “charge” that fast. This is solely due to the fact that the engine doesn’t have a load on it when your car is simply idling.
Do alternators rob horsepower?
If you then consider the mechanical power required to spin and cool the alternator your overall efficiency drops to about 20-25% including the engine losses. If you like to deal in HP, then 1.5kW is about 2HP. At an overall efficiency of 20% this means you will need about 10HP from an engine to provide this.
How do I change my 12V alternator to 24v?
How Do I Charge a 24V From a 12V Alternator?
- Purchase a 12v to 24v converter.
- Unscrew the screws on the terminal block of the converter, this is the point where the input and output wires connect to the converter.
- Connect the output of the converter to the 24v battery with standard terminal wire.
How to get 120V or 240V from a car alternator?

How to turn a car alternator into a generator?
Turn a car alternator into alternative energy by building this cheap and easy homemade wind generator. If you can turn a wrench and operate an electric drill, you can build this simple generator in two days. You can use any vehicle alternator with a built-in voltage regulator.
How to convert 12 volt alternator to 120 volts?
You can simply make a generator, using a car alternator. To get a high voltage output, use a step-up transformer or if output is rectified, you can also use
How to use a car alternator to make alternative energy?
How to Use a Car Alternator to Make Alternative Energy. Step 1 – Choose the Right Alternator. The type you want to use for this project should be an older design, such as you might find in a scrap yard. Step 2 – Connect the Alternator. Connect the device to a 12-volt battery to provide stability in the system.
