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: An inverter-integrated rotating electrical apparatus includes a rotating electrical machine and an inverter case. The rotating electrical machine has a housing. The housing has an end wall, which is located at an axial end of the rotating electrical machine. The inverter case accommodates inverter components fixed to the outer surface of the end wall of the housing. The inverter case includes a metal plate portion that faces the end wall of the housing. The metal plate portion forms a heat sink for cooling the inverter components. The metal plate portion has thereon cooling fins located on the outer surface of the inverter case. The metal plate portion also includes therein an accommodating recess located inside the inverter case. The accommodating recess is recessed toward the end wall of the housing and accommodates a capacitor, which is an inverter component.
