Ring Magnets

Generals

Most of them are used for small DC Motors and low noise devices and equipments due to their lower noise and vibration characteristics than segment type magnet .
Especially, Ring magnets for Multipole are typically used for stepping motors.

Applications

Small DC Motor - Door on-off motors for elevators, Motors for Aqua, Dash washer, Water circulation and Discharging
Stepping Motor - ISA for automobiles, Wind direction regulator for Air conditioner, Frost remover for refrigerators.
