Abstract
A Fourier analysis of the output voltage waveshapes of low-frequency sources shows that, depending upon the order, a harmonic component of the voltage may contribute either positive, negative, or no torque. Using the concept of rotor-time-constant expressions for total developed torque, stator current and copper losses are derived for a voltage wave composed of harmonics of various magnitudes and orders. The stator current is affected if the motor neutral is connected to the supply neutral.Keywords
