NdFeB is a permanent magnet material and an indispensable part of permanent magnet motor. Rare earth permanent magnet motor is the largest application field of NdFeB magnet, accounting for 70% of the total magnet, and the ring motor of computer hard disk (VCM) ) 40% to 50%, so the computer industry is the largest user of permanent magnet motors.
Common permanent magnet motors : permanent magnet DC motors, permanent magnet AC motors.
Permanent magnet DC motors : brushed DC motors, brushless motors, stepper motors, etc.
Permanent magnet AC motors : synchronous permanent magnet motors, permanent magnet servo motors, etc.
