Electromagnetic and Electromechanical Compatibility Improvement of a Multi-Winding Switch Control-Based Induction Motor—Theoretical Description and Mathematical Modeling

The main advantages of multi-winding (multiphase) induction machines include reducing torque ripple, decreasing rotor harmonics losses, the current per phase without increasing voltage phase, DC source, and high fault tolerance. authors propose a theoretical description for harmonic content DC-link current, magnetomotive force, electromagnetic machine (IM), an account interaction time power supply spatial winding functions is presented. proposed analysis has made it possible to substantiate supply-winding schemes compensation higher (6th 12th in IM’s torque) improvement electromechanical compatibility machine, which are justified according description. Further, schematic solution motor with electronic changing pole number provide reduction speed ripples at low rotation speeds. This decrease ensured by pairs frequency voltage. Mathematical models switch control-based developed using method average voltages integration step investigation processes. It shown that distinguished response accuracy. confirmed comparative known methods Matlab environment, as well comparison simulation results physical experiments. mathematical modeling show use IM appropriate stands significantly reduce case six-step source inverters. makes this type inverter suitable frequency-controlled electric drive alternative PWM inverter, negative influence on state.
