An Influence of Spatial Harmonics on an Electromagnetic Torque of a Symmetrical Six-Phase Induction Machine

The analyses of the influence spatial harmonics on electromagnetic torque multi-phase induction machine and reducing this are important tasks to ensure high efficiency machine. Designing consider is essential desired mechanical energy characteristics. In case sinusoidal winding supply machine, magnetomotive force has harmonics, which caused by machine-winding design. interaction between 5th, 7th, 11th 13th function first time-harmonic causes appearance 6th 12th in A prototype symmetrical six-phase experimental study for harmonic content stator currents different modes given paper. mathematical model been developed using average voltages integration step method. introduction components into magnetization inductance taking account proposed adequacy was confirmed comparing simulation results. torque, influence, analyzed.
