To propel an electric vehicle, electricity must be converted to mechanical force. Electric motors use current flowing through wires to create magnetic fields that interact with other magnetic fields in the motor to create motion.
Contents
Brushed DC Motor
Conventional motor. Very easy to apply power. Does not require a sensor to track the rotation of the motor.
Brushless DC Motor
Known for their trapezoidal waveforms. Typically uses an encoder to track the rotation of the motor.
Permanent Magnet Synchronous Motors
Known for their sine waves. Typically uses a resolver to track the rotation of the motor. Can also use sensorless feedback based on the back EMF of the motor.
