Electromagnetic noise of induction motors driven by PWM inverters
When a squirrel cage induction motor is driven by a PWM inverter, electromagnetic noise different from that during commercial power source drive is experienced. This is because of sideband wave voltage induced in PWM inverter output voltage. This paper first describes the mechanism of electromagneti...

| Zusammenfassung: | When a squirrel cage induction motor is driven by a PWM inverter, electromagnetic noise different from that during commercial power source drive is experienced. This is because of sideband wave voltage induced in PWM inverter output voltage. This paper first describes the mechanism of electromagnetic noise generation in commercial power source drive, and then electromagnetic force considering the sideband frequency and voltage content and the mechanism of electromagnetic noise generation in PWM inverter drive. It also refers to the sideband frequency and voltage content because of operating time control. © 2000 Scripta Technica, Electr Eng Jpn, 133(3): 55–62, 2000 |
