Abstract: Provided is a method for calculating iron loss resistance of a variable frequency motor while considering PWM harmonic waves, which falls within the field of loss analysis and calculation of an alternating current motor. The method is used for expressing the iron consumption resistance of an induction motor as a function of induction potential and rotational speed on the basis of a segmented variable coefficient iron loss model. According to the method, additional iron loss generated by harmonic waves of a PWM frequency converter and surface and pulse vibration loss generated by space harmonic waves of the motor are considered. By using the method, an accurate variable frequency motor equivalent circuit while considering the iron loss can be acquired. Finally, taking a 5.5 kW variable frequency induction motor and a 30 kW variable frequency induction motor as examples, a change rule of the iron loss resistance of the variable frequency induction motors is acquired. The two induction motors are used for verifying the effectiveness of this method.
