摘要： An asynchronous salient pole induction motor having a stator core (12) with equally-spaced teeth (16) with inner ends (20) having equal angular extent and defining a bore whereat a squirrel cage rotor is provided. A main field winding (34) includes serially connected coils embracing alternate stator teeth and connected across a single phase source of alternating current. An auxiliary field winding (38) includes serially connected coils embracing consecutive teeth intermediate the teeth having the main winding coils thereon. The auxiliary winding coils are phase displaced from the main winding coils. Each of the teeth faces at their inner ends are shaped for increasing the air gaps on both sides of the center line longitudinal plane of each tooth thereby increasing the magnetic reluctance between each of the teeth and the rotor on both sides of the center line plane. The laminations are first punched with circular shaped teeth inner ends and thereafter are punched to remove a cut-away portion from the teeth inner ends substantially near the tips (52) of the teeth furthest away from the center line plane.
