ROTOR-HOLDING STRUCTURE OF ROTATING ELECTRICAL MACHINE FOR HYBRID VEHICLE

摘要

It is an object of the present invention, to provide a rotor-holding structure of a rotating electrical machine for hybrid-vehicle, the structure being capable of ensuring a space is present between a stator and a rotor. A rotating electrical machine includes a stator and a rotor, the stator being fixed to a housing, and the rotor being disposed opposite to stator across a predetermined space, wherein the rotor has a rotor boss section, a rotor core, and a permanent magnet. The rotor boss section is rotatably attached to the housing through a bearing. The rotor core and the permanent. magnet are attached to the rotor boss section. Multiple through-holes are provided at the respective corresponding locations of the housing and the rotor boss section. A supporting member is passed through each of the through-holes, thereby holding the rotor boss section.

1. A rotor-holding structure of a rotating electrical machine for hybrid vehicle, comprising:
a stator fixed to a housing: and a rotor oppositely spaced apart from the stator by a predetermined space, the rotor-holding structure being characterized in that:
the rotor has a rotor boss section rotatably attached to the housing via a bearing and a rotor core and a permanent magnet both attached to the rotor boss section; andmultiple through-holes are provided to each of the housing and the rotor boss section at locations at which the respective through-holes in the housing correspond to the respective through-holes in the rotor boss section, so that the rotor boss section is held by inserting supporting members into the respective through-holes.
