Comparison of AC Motors to an Ideal Machine Part II-Non-Sinusoidal AC Machines

摘要

This two-part paper compares the torque performance of 12 types of AC machines based on the same current level, flux level and rotor dimensions. Part II examines the torque capability of machines more recently developed which utilize the wave shaping capability of a solid-state frequency inverter. Essen's Equation, as utilized in Part II is modified to accommodate machines requiring non-sinusoidal waveforms. The “tau” factor, introduced in Part I is also modified and is again used as means for comparison of any AC machine with an “ideal” machine based now upon a modified form of Essen's Equation.
