WHAT IS RARE-EARTH PERMANENT MAGNET MOTOR?
WHAT IS RARE-EARTH PERMANENT MAGNET MOTOR? WHAT IS RARE-EARTH PERMANENT MAGNET MOTOR As the name implies, rare-earth permanent magnet motors use rare-earth materials inside the motor. NdFeB rare-earth magnets are embedded in the rotor. The inherent magnetic field of the magnet is used as an excitation source to form a fixed magnetic pole. When the [...]
