ac motors vs dc motors for electric car?
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. .
Energy that is used to power the electric cars is stored in batteries. To run an AC motor you have to convert the DC from the battery to AC current. To make it simpler, a DC motor should be used as it can be driven by DC current.
Direct Current DC motors are the most popular do it yourself choice for EV conversions for a few reasons. Firstly, they are the least expensive and most readily available EV motors.
The ac motor used less wicky math than the dc motor to look cool in their science fare, ac motor. But you get that just running a current in a circle works great?
Hi. AC motors are designed and built differently than DC motors. AC motors take advantage of the 60 hertz clock of a power line (or 50Hz in other countries) - this means the power line changes phases 60 times a second - to rotate, while DC motors are designed with the voltage level applied. You can control them both, but with different means. The easiest to control is the DC motor (change the potential (the voltage) and it turns slower or faster.
