  • Six-phase AC induction motor drive system and method therefor
    Patent number: 9287818
    Abstract: A drive system powers a six-phase AC induction motor having a plurality of poles and a stator with a plurality of teeth where the number of teeth divided by six times the number of poles equals an integer number. The stator core has first and second groups of three-phase stator windings. The second group of three-phase windings is separated spatially by 30 electrical degrees from the first group. A first power supply is connectable to the first group of three-phase windings. A second power supply is connectable to the second group of three-phase windings. The second power supply provides power to the second group of three-phase windings that is shifted by 30 electrical degrees in time with respect to the first power supply. The first and second power supplies receive signals from identical pulse width modulator generators. The respective first and second pulse width modulator generators receive commands from one controller.
