Calculation of Rotor Harmonic Losses in Multiphase Induction Machines

Machines, 2022
The topic of this paper is the determination of rotor harmonic losses in multiphase machines. Specifically, harmonic losses occur in the rotor winding and core due to higher-order spatial harmonics of the flux density.

Asymmetrical Six-Phase Space Vector Pwm Scheme

Mokslas: Lietuvos Ateitis, 2014
Multiphase electric motors have smaller torque pulsations and are more reliable that their three-phase alternatives. However, standard electricity grids around the world are three-phase, so power inverter is needed to drive multiphase motors. Inverter is
