What type of motor is used in electric vehicles?
1 Answers
Electric vehicles use ferrite permanent magnet DC servo motors. The function of the motor is to generate driving torque as the power source for electric vehicles. Classification of electric vehicle motors: AC motors, DC motors, universal motors, control motors, switched reluctance motors, and signal motors. Working principle of the motor: Utilizing energized coils to generate a rotating magnetic field that acts on the rotor to form an electromagnetic rotating torque. Motor maintenance methods: 1. Regularly clean the small grooves between the commutator segments and the carbon powder on the commutator surface; 2. Avoid high-speed no-load starting; 3. Regularly open the louver to check whether the commutator and brushes are normal.
