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 much power can an alternator produce as a motor?
But nowadays, a single alternator can produce power up to 2500 Watt, depending on the power demand. The power that can be produced by an alternator is determined by the alternator rating. The output of the alternator ranges from 40 Amp up to 120 Amp. For high-amp alternator, it can generate up to 300 Amp.
How powerful is an alternator motor?
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. An automotive alternator converted to a motor is much less expensive than a conventional brushless motor with the same power output.
Is alternator and motor the same?
As nouns the difference between alternator and motor
is that alternator is an electric generator which produces alternating current through mechanical means while motor is a machine or device that converts any form of energy into mechanical energy, or imparts motion.
Can you turn an alternator into a generator?
If you want to use it as a generator you will still need excitation DC source, or you can modify it for self excitation, the output will be three phase, unless you wish to keep the rectifier module and have it output DC. Automotive alternators have a 3 phase output…
What is the minimum RPM of a 12v car alternator?
As was stated before, most alternators prefer a minimum speed of 2,400 rpm.
How much power should an alternator put out?
An alternator should put out between 13.5 and 15 volts of power. The alternator should be tested with the engine idling and electrical accessories, such as the radio and headlights, turned off.
Can high rpm damage alternator?
TOO HIGH OF RPM WILL DAMAGE ANYTHING. INCLUDING ALTERNATORS. YOU IMPORTANTLY MUST BE AWARE THAT IF THE ALTERNATOR IS BELT DRIVEN, THE DIFFERENCE IN SIZE OF THE TWO BELT PULLEYS MIGHT HAVE THE ALTERNATOR TURNING FASTER THAN THE ENGINE RPM, MAYBE MANY TIMES FASTER.
