An Influence of the Time and Spatial Harmonics on an Electromagnetic Torque of a Symmetrical Six-Phase Induction Machine With a Six-Step Inverter Supply Under Open Phase Circuit Fault

Six-phase induction machines offer several advantages over traditional three-phase machines, including higher levels of electromechanical compatibility with loads, energy efficiency, and fault tolerance.

This article presents an analysis of the impact of harmonics in the winding distribution function in the stator slots and the harmonics of the machine’s supply on its electromechanical compatibility with the load during a single-phase failure.

Mathematical modeling of frequency-controlled electric drive with dual-winding induction machine considering spatial harmonics

Mathematical modeling of frequency-controlled dual-winding induction electric drives typically involves using mathematical circuit models to investigate transient and steady-state modes. Such models often disregard spatial harmonics. Spatial harmonics in machines refer to the harmonics of the distribution of the winding function within the machine stator slots. Mathematical models based on the method of finite element analysis are primarily used to study the influence of spatial harmonics on the stator current and electromagnetic torque of dual-winding machines.
