Inverter drive of 400 V class motor
When the wiring between the inverter and motor is long, surge voltage occurs at the terminal of the motor.This surge voltage deteriorates insulation of the m... More Details >>
When the wire between the 400 V inverter and motor is long (20 m or longer), surge voltage occurs momentarily. This voltage is as two or more times as the DC... More Details >>
Surge voltage of 400 V inverter
No. Although the carrier frequency increases or decreases the switching count, the switching speed is the OFF-to-ON speed of the IGBT element of the inverter... More Details >>
Power factor improving effect by option
