Using the Inverter for a Motor
H Motor Burnout Caused by Insufficient Dielectric Strength of Each
Phase of Motor
Surge occurs among the phases of the motor when the output voltage is switched.
If the dielectric strength of each phase of the motor is insufficient, the motor may burn out.
The dielectric strength of each phase of the motor must be higher than the maximum surge voltage.
Normally, the maximum surge voltage is approximately three times the power voltage imposed on the
Inverter.
