ABSTRACT:
A drive system for a laundry machine utilizing a switched reluctance motor of three or more phases and with stator/rotor pole ratios selected from the ratios of 6:4 and 8:6 with the actual number of poles being a multiple of 2 or more times those numbers. A stator/rotor gap of 10-20 mils is maintained in large diameter motors and cooling for the coils and electronic components positioned within the motor is provided.
