Micro DC Motor - Brushless DC Motor - NFP-BL-1625WH

Solution Of Permanent Magnet Motors' Cogging Torque Problem

Cogging torque maybe a terrible problem for your application, the best way to solve this problem is to use a coreless design, brushed or brushless types. NFP-BL-1625 motor is just the type of coreless motor.

 

There is no cogging problem in coreless motors, due to them having a uniform 360 degree magnetic stator field and no permanent magnetic circuit elements in the rotor. This means that there is no case where the rotor and stator magnetic circuits are falling in / out of alignment. To learn more about the permanent magnet motors' cogging torque from the following link:
