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.
