Abstract :
Characteristics of variable frequency power supplies are compared, including sine wave, six-step square wave, and pulse width modulated (PWM) types. The effects of the complex voltage waveforms and variable frequency supplies on motor efficiency, heating, torque, winding stresses, and low speed pulsating torques are described. Possibilities for customizing induction motors for use with variable speed drives are considered.
