Abstract

A controller-included rotating electrical machine is provided which includes a rotating electrical machine and a controller. The controller 11 is equipped with a power supply terminal-included bus bar assembly and bus bar assemblies. The power supply terminal-included bus bar assembly has bus bars which are fixedly retained by resin and electrically wire a power modules and also includes a power supply terminal connecting with one of the bus bars. Specifically, the power supply terminal is installed in the power supply terminal-included bus bar assembly along with the bus bars, thereby resulting in decreased number of parts and production steps of the controller-included rotating electrical machine as compared with a conventional structure equipped with a power supply terminal and bus bars which are fabricated as assemblies and a power supply terminal installed in another assembly.

First claim

What is claimed is:

1. A controller-included rotating electrical machine comprising:
a rotating electrical machine;
a plurality of switching device modules each of which includes a plurality of switching devices and constitutes an inverter circuit working to supply alternating current to the rotating electrical machine and a rectifier circuit working to rectify alternating current, as delivered from the rotating electrical machine;
a power supply terminal-included bus bar assembly which includes a plurality of kinds of bus bars which electrically wire one of the plurality of switching device modules and are fixedly retained by a resin member, the power supply terminal-included bus bar assembly also including a power supply terminal for connection with an electrical conductor extending from a positive pole of a power supply, the power supply terminal being joined to one of the bus bars; and
at least one other bus bar assembly which includes a plurality of kinds of bus bars which electrically wire one of the plurality of switching device modules and are fixedly retained by a resin member.

2. The controller-included rotating electrical machine as set forth in claim 1 , wherein the power supply terminal-included bus bar assembly includes a metallic fixation member which is fixedly retained by the resin member with the bus bars of the power supply terminal-included bus bar assembly and secures the power supply terminal thereto, and wherein the one of the bus bars which is joined to the power supply terminal is secured by the power supply terminal to the fixation member in contact with the fixation member.

3. The controller-included rotating electrical machine as set forth in claim 1 , wherein the power supply terminal-included bus bar assembly and the at least one other bus bar assembly are provided one for each of the plurality of switching device modules.

4. The controller-included rotating electrical machine as set forth in claim 1 , wherein the power supply terminal-included bus bar assembly and the at least one other bus bar assembly are arranged adjacent each other and secured to a housing of the rotating electrical machine using a bolt.

5. The controller-included rotating electrical machine as set forth in claim 4 , further comprising:
a cover which is secured to the housing of the rotating electrical machine using the bolt together with the power supply terminal-included bus bar assembly and the at least one other bus bar assembly to cover the plurality of switching device modules, the power supply terminal-included bus bar assembly, and the at least one other bus bar assembly.
