Abstract
A rotating electrical machine such that positional deviation caused by a part tolerance can be absorbed in an electrical connection between a power conversion device and a rotating electrical machine main body, and size can be reduced without a structure becoming complex, is obtained. The rotating electrical machine is characterized by including a power terminal unit of the rotating electrical machine main body housed in a housing, the power conversion device fixed to the housing, and a multilayer bus bar connected to the power terminal unit of the rotating electrical machine main body as a power terminal of the power conversion device, wherein the multilayer bus bar has flexibility, and is bent by being connected to the power terminal unit.
Claims8
A rotating electrical machine, comprising:
- a power terminal unit of a rotating electrical machine main body housed in a housing;
- a power conversion device fixed to the housing;
- and
- a multilayer bus bar connected to the power terminal unit of the rotating electrical machine main body and a terminal unit of the power conversion device, wherein
- the multilayer bus bar has flexibility, and is bent by being connected to the power terminal unit,
- the multilayer bus bar includes a first through hole for screw-fastening to the power terminal unit and a second through hole for screw-fastening to the terminal unit of the power conversion device, and
- a first gap between the first through hole and a first screw inserted into the first through hole is larger than a second gap between the second through hole and a second screw inserted into the second through hole.
