If electric cars are to be mass produced what type of motor?
Today, AC induction motors are better for almost all applications, as you can use a VFD, variable frequency drive to supply the motor with the proper frequency and voltage for the desired load and speed. And an electric auto can afford the complexity of the VFD. For a school project, a DC motor would be better. .
DC Motor. while technically you can use either, a DC motor is better in this type of application for a couple of reasons: DC Motors approach infinite torque as their speed approaches 0 RPM giving them a better ability to move off the starting line. You can also use this to gear them more efficiently. AC is in the home instead of DC because it transmits across power lines better. The distance you can transport voltaic energy using DC is ridiculously short, plus high voltages transmit long distances better and AC can be converted easier through transformers. In Motor theory AC has an advantage that through a brushless motor is up to 30% more efficient than a DC motor and has a much higher RPM limit. This comes at the cost of extremely expensive inverter electronics and ESC's. For mass production the cheap DC motor would win out in a capitalist economy.
Electric cars can use AC or DC motors... If the motor is a DC motor, then it may run on anything from 96 to 192 volts, if it is an AC motor, then it probably is a three-phase AC motor running at 240 volts AC with a 300 volt battery pack. DC installations tend to be simpler and less expensive.
Electric current is either AC - alternate current like in your home, or DC - direct current, like from the batteries themselves. Both have been used successfully in electric vehicles. AC has to have an inverter converter to get usable energy from batteries. In other words getting AC from DC batteries. IT would also take a different motor to run the vehicle. Your choice.
