ABSTRACT:
A dynamo-electric machine includes a stator core fixed in a casing and formed of stator lamination plates, and a rotor supported in a bore of the stator core and formed of a stack of rotor lamination plates. Each stator lamination plate has a tooth portion extending radially outward from the bore to an intermediate circumference, and a yoke portion defined between the intermediate circumference and the outer periphery of the stator lamination plate. Each of the rotor lamination plates has a number of equally circumferentially spaced closed slots, wherein each slot is defined by a curvilinear edge at an upper slot region adjacent the periphery of the plate. The curvilinear edge together with a pair of spaced parallel sides together define a top part of each slot, the top part opening into a bottom part of the slot which is substantially triangularly-shaped. In one embodiment the teeth of the stator lamination plates are sufficiently wide relative to the area of stator slot openings so that the ratio of flux density in the tooth portion to flux density in the yoke portion is optimized for a given n pole operating configuration of the stator winding.
