Motor Burnout Caused by Insufficient Dielectric Strength of Each
Phase of Motor
When using the Inverter to control a motor, surge occurs among the phases of the motor when the
Inverter's output voltage is switched (PWM).
If the dielectric strength of each phase of the motor is insufficient, the motor may burn out.
Use a motor with a dielectric strength among the phases of the motor that is higher than the maxi-
mum surge voltage (i.e., three times the maximum power supply voltage).
