Motor Burnout Due to Insufficient Dielectric Strength of Each Phase of
the 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.
Be sure to connect a dedicated motor to the 400-V Inverter. A standard motor may burn out if it is con-
nected to the Inverter due to the insufficient dielectric strength of each phase of the standard motor.
