Electric vehicle sales are growing in India and abroad because of its low operating cost and less harmful impacts on the environment. Till mid-June, 6.89 lakhs EVs (including 2W, 3W, and 4W) have been sold in India.
An electric vehicle motor has to face wide variation in speed within a few seconds. EV motors have wide operating parameters like temperature and vibrations.
The opposite poles of the magnet attract each other. This same principle is used for the operation of BLDC motors.
Brushless direct current motor (BLDC)
PMSM motor is run by AC source of power not DC like BLDC motor. When three-phase AC power is given to the stator, a rotating magnetic field is produced by the stator.
Permanent Magnet Synchronous Motor (PMSM)
It works on the principle of magnetic reluctance. It means that the magnetic flux chooses the path which has the least magnetic reluctance. The magnetic flux from the stator takes this least magnetic reluctance path.
