Permanent Magnet Motor Drives in
Electric Vehicles
Permanent magnet motors are widely used
in electric vehicles (EVs) due to their high
efficiency and performance. These motors
utilize permanent magnets to create a
magnetic field, eliminating the need for
external excitation. Types of Permanent Magnet
Motors in EVs
1. Permanent Magnet Synchronous Motor
(PMSM):
¢ Operates with a rotating magnetic
field in sync with the rotor.

2. Brushless DC Motor (BLDC):

control systems.
