ROTARY ELECTRIC MACHINE AND METHOD OF MANUFACTURING ROTARY ELECTRIC MACHINE

摘要

In a rotary electric machine, wound wires are connected to a first terminal and a second terminal. Circuit terminals that are configured from a conductive metal other than aluminum, and the first terminal and the second terminal that are configured from a metal with a principal component of aluminum are joined together inside a circuit chamber that has high water resistant properties. Corrosion is accordingly suppressed at join sites of the circuit terminals with the first terminal and the second terminal. There is therefore no need to coat the join sites with for example a sealing material in order to suppress corrosion at the join sites. Good electrical continuity is accordingly enabled between the circuit terminals and the wound wires whilst suppressing an increase in costs, even when the wound wire is configured from a metal with a principal component of aluminum.

主权项

1. A rotary electric machine, comprising:
a cover that configures an outline of a sealed circuit chamber; a drive circuit section that is housed inside the circuit chamber and that drives a motor section; a circuit terminal that is provided at the drive circuit section inside the circuit chamber, and that is configured from a conductive metal other than aluminum; and a wound wire that is wound around a tooth portion of an armature core in the motor section, that is configured from a metal whose principal component is aluminum, and that has a terminal portion that is directly joined to the circuit terminal or is joined to the circuit terminal via a coupling member that is configured from a metal whose principal component is aluminum.
