For the motor winding, the insulation requirements between turns and turns, between different phases of a multi-phase motor, and between the conductor and the ground are involved. When the rated voltage of the motor is higher, the voltage of the winding insulation is also higher, which can be simply Think of this as different capacitors. If the voltage between the capacitors is too high, it will lead to the problem of capacitor breakdown, that is, the insulation failure of the motor winding to ground, between turns and between phases.
