Reducing speed motor is actually a kind of motor. The stator in the motor is related to the performance of the motor. Experts analyze that the more slots in the stator, the better the magnetomotive potential of the motor, the smaller the leakage reactance of the motor, resulting in the increase of the maximum torque and starting torque, efficiency and power factor slightly increased. The heat dissipation area of the loose and winding contact core is increased, which is favorable for heat dissipation. But not the more the number of slots, the better, this is not necessarily, the more the number of slots, will lead to the increase of slot insulation materials and man-hour, slot utilization rate will be reduced, the manufacturing and use of punch die is not conducive.

The energy of the decelerating motor should be constant and the number of grooves should be specified.
