Title:
ROTOR-HOLDING STRUCTURE OF ROTATING ELECTRICAL MACHINE FOR HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/170940
Kind Code:
A1
Abstract:
It is an object of the present invention to provide a rotor-holding structure of hybrid-vehicle rotating electrical machine, said structure capable of ensuring a space is present between a stator and a rotor. A rotating electrical machine comprises 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.
