Brushless motor stator slot shape -

Brushless motor stator trough, there are four basic enough, but some motor trough and the four channel, as long as the stator laminations tooth width is constant, the motor of the channel even if some changes, but the area of the slot some change, so motor slot utilization is slightly changed, the performance of the motor change is not big, groove area after the change, utilization rate of slot can be corrected
