An induction motor embodiment includes a stator defining a stator bore, the stator including a stator yoke having a stator yoke thickness and a plurality of stator teeth, the teeth having a common length, with each of the stator teeth including a stator tooth center portion that extends from a stator tooth bottom portion proximal the yoke to a stator tooth tip portion, with adjacent stator teeth defining a stator slot between them, each stator slot having a stator slot bottom that extends along a stator slot bottom length. In the embodiment, the center portion has a stator tooth width that is less than or equal to one half the stator slot bottom length. In the embodiment, the stator tooth width is smaller than a stator slot opening width distance. In the embodiment, a ratio of stator yoke thickness to stator tooth width is at least 5:1. A rotor is rotably mounted in the stator. |
