US Patent 7948130 Rotating electrical machine

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.
