About motor slot
About the Number of Slots in the Stator and the Slot of the Rotor in Asynchronous Motors
First, the total mass of the rotor bar of the asynchronous motor must be sufficient to handle the heat generated by the high current during the transient (start-up) state.
Second, the number of rotor bars (slots) of asynchronous motors must be slightly different from the number of stator slots to minimize electromagnetic noise and noise.
Third, the number of asynchronous motor rotor bars must be different from the number of stator slots the rotor must turn (for example, it cannot be locked in place due to insufficient torque).
If the rod (or the rod/ring joint at the end) is completely broken, the rotor winding will have a measurable torque disturbance and slightly higher thermal load during operation. During the transient (start-up) sequence, it does not produce considerable torque. The more damaged joints, the greater the disturbance and the smaller the torque. In order to avoid torque, noise and harmonic problems, there are certain rules in the selection of the number of slots in the stator and rotor of the asynchronous motor.
