A harmonic loss calculation of PWM-fed induction motors using loss factor characteristics

This paper presents a harmonic loss calculation of PWM-fed induction motor, based on harmonic loss factor curves under load conditions and various motor configurations. The individual harmonic losses can be calculated from loss factor characteristics and individual harmonic voltages squared. The calculation results can be guidelines for selection of PWM parameters suitable for drive applications such as switching frequency and can suggest useful advices to the motor designers and users, when induction motors fed by PWM inverters have to be designed or utilized.
