发齿槽音时用节拍发出。

To keep time by counting beats.

提出了一种由步进电机、转矩传感器等元件组成的齿槽转矩测试系统。

A cogging torque measurement system was proposed, which was composed of stepping motor, torque sensor, etc.

永磁电机中永磁体与有槽电枢铁心之间相互作用，产生齿槽转矩，引起电机振动和噪声。

Due to the interaction between the permanent magnet and slotted armature lamination, there exists cogging torque in slotted permanent magnet motors, which may cause noise and vibration.
