Abstract
The present invention discloses a stator assembly for a dual three phase inverter-driven motor. The stator assembly includes: a radially disposed matrix of phase belts each having several pole groups, such phase belts being disposed at fixed radii from the axis of the rotor of the motor, each of the pole groups therein comprising twelve stator slots; a first plurality of three phase motor windings, each of such windings having a span length of either stator slots within its respective pole group, each pole group winding of said first plurality of motor windings having two coils per pole group, the first of such coils of each pole group being wound upon the i and i+8 stator slots, and the second coil of each pole group being wound upon the i+1 and i+9 stator slots; and a second plurality of three phase motor windings, each of such windings having a span length of eight stator slots, each pole group winding of said second plurality of motor windings having two coils per pole group, the first coil of each pole group being would upon the i+2 and i+10 stator slots, and the second coil of each pole group being wound upon the i+3 and i+11 stator slots, said two pluralities of motor windin…
