Abstract: An induction machine includes: a stator having a stator core and a coil; a rotor, which has a shaft, a rotor core secured to the shaft, and a secondary conductor; a bearing supporting the shaft; a cooling fan having a blade; and a cooling fan fixture. The secondary conductor includes a rotor bar and an end ring. The blade is located axially outward of the end ring, and the distal end of the blade in the axial direction extends axially outward of the coil end of the coil. The cooling fan has a securing portion located radially inward of the end ring and a cylindrical extended portion extending from the securing portion to the blade. The securing portion is secured to the rotor with the cooling fan fixture. The bearing is located axially inward of the distal end of the blade.

Abstract: A stator of a rotary electric machine includes a stator core and polyphase coils. The stator core has a plurality of slots. The polyphase coils are provided in the slots. Each phase of the polyphase coils has a plurality of coils formed for each pole and connected in parallel. When winding in which a coil pitch is equal to number of slots divided by number of poles is termed full-pitch winding, when winding in which a coil pitch is larger than the coil pitch of the full-pitch winding is termed long-pitch winding, and when winding in which a coil pitch is smaller than the coil pitch of the full-pitch winding is termed short-pitch winding, at least two of the coils of each phase are formed on the stator core by wave winding to alternate between the long-pitch winding and the short-pitch winding along a circumferential direction of the stator core.
