  • Multiphase induction motor drive for gearless electric vehicles
    Patent number: 11870381
    Abstract: A Pole Phase Modulated (PPM) nine-phase induction motor drive may be used in gearless electric vehicle applications. A single stator winding multiphase induction motor may deliver variable speed-torques by varying the number of phases and poles with respect to a multiphase power converter. A multilevel inverter controlled with carrier phase shifted space vector pulse width modulator (PWM) may further improve the PPM based multiphase induction motor (MIM) drive with respect to efficiency, torque ripple, and direct current (DC) link utilization. To operate the PPM based MIM drive smoothly in different pole phase combinations, indirect field oriented vector control may used.
