Abstract

A rotating electrical machine includes a stator of which winding terminals are connected to conductive members using a connection substrate on which the conductive members are disposed and which includes an insulating plate. The connection substrate includes a plurality of circumferential grooves and a plurality of radial grooves. The conductive members are fitted to the circumferential grooves in a concentric manner. The conductive members coated with insulating films are formed in a bent shape such that the conductive members project from the radial grooves to an outside of the connection substrate and are connected to the winding terminals of the stator.

Claims

1. A rotating electrical machine comprising:

a stator of which winding terminals are connected to conductive members using a connection substrate on which the conductive members are disposed and which comprises an insulating plate,

wherein the connection substrate includes a plurality of circumferential grooves and a plurality of radial grooves, the conductive members being fitted to the circumferential grooves in a concentric manner,

wherein the conductive members coated with insulating films are formed in a bent shape such that the conductive members project from the radial grooves to an outside of the connection substrate and are connected to the winding terminals of the stator,

wherein the connection substrate has a first surface and a second surface opposite to the first surface, and

wherein the circumferential grooves and the radial grooves are provided at both the first surface and the second surface of the connection substrate.

2. The rotating electrical machine according to claim 1, wherein the circumferential grooves and the radial grooves in the connection substrate are provided with claws that are configured to prevent the conductive members from falling.

3. The rotating electrical machine according to claim 1,

wherein terminal portions of the conductive members connected to the winding terminals of the stator are formed in a helical shape, a split-pin shape, or a scissor shape instead of the bent shape.

4. The rotating electrical machine according to claim 1, wherein the circumferential grooves and the radial grooves are provided at substantially the same positions on both the first surface and the second surface of the connection substrate.

5. A rotating electrical machine comprising:

a connection structure of a stator of which winding terminals are connected to conductive members using a connection substrate on which the conductive members are disposed and comprises an insulating plate,

wherein each of the conductive members includes a connecting terminal, a copper wire, and an insulator,

wherein the connection substrate includes supporting portions formed as axially extending rods that are configured to receive a hole on each of the connecting terminals and support the connecting terminals of the conductive members, and

wherein the connecting terminals of the conductive members coated with insulating films are attached to the supporting portions such that connecting portions of the connecting terminals project to an outside of the connection substrate and are connected to the winding terminals of the stator.
