Abstract
A stator assembly for a multiple-pole (e.g., an 18 pole) induction motor is disclosed having a main winding and an auxiliary winding with the main and auxiliary windings each having a first and a second coil set, each of these coil sets having multiple coils selectively electrically connected together. The stator assembly further includes a core having slots therein for receiving the coils. There is one coil of the first auxiliary winding coil set inserted in the first and third slots of the core, one coil of the first main winding coil set inserted in the second and fourth slots, one coil of the second auxiliary winding coil set inserted in the third and fifth slots, and one coil of the second main winding coil set inserted in the fourth and sixth slots thereby to form a layered coil insertion pattern of the coils in the first six slots of the core. Second coils from each of the coil sets are then inserted in a similar layered fashion in the slots 5-10 of the core to form another layered insertion pattern of the coils in the slots. This layered insertion pattern is repeated until all of the coils are inserted into the slots of the core. A method of fabricating such a stator assemb…
