Often while conversion of car it becomes a dilemma for people that whether they should choose AC or DC electric motor. Since, both of them have different features and challenges to face, it becomes a point of debate that which one is good for a car. But, comparing your requirements with their feature all perplexities can be eliminated.
As far as AC (Alternating current) electric motors are considered, they are, preferred by commercially produced electric or hybrid cars. This is because of their lighter weight than DC (direct current) electric motors and their ability to produce charge to the batteries when the car slows down. This process is known as regenerative braking. The AC electric motor is used to slow the vehicle down when the motor spins and generates current which is supplied to the battery pack.
The downside of AC motors says that there are also some challenges to be faced when they are installed. One of them is their excessive high cost. This is why often some people opt for DC motors when it is about reducing car conversion cost. However, this doesn’t mean that DC electric motors are can be graded low. There are many occasions when DC motors are suitable. If used ones are picked up from the market and reconditioned, it will cost quite low and also such choices last long because their servicing life is longer than conventional fueled engine. Reason, this electric motors have only one part that is moving, unlike diesel and gasoline that hundreds of moving part. Electric motors generate lesser heat, so almost no cooling is required and there no part frictions with each other so there is no need for lubrication either. So there are both pros and cons of AC and DC motors.
