When a squirrel cage induction motor is driven by a PWM inverter, electromagnetic noise different from the one during commercial power source drive is experienced. This is because of sideband wave voltage induced in PWM inverter output voltage. This paper describes the mechanism of electromagnetic noise generation in commercial source drive, then electromagnetic force considering the sideband frequency and voltage content and the mechanism of electromagnetic noise generation in PWM inverter drive. It also refers the sideband frequency and voltage content because of operating time in control.
