Abstract:
An inner-rotor-type brushless motor includes a bus bar which connects together U-phase, V-phase, and W-phase windings and connects them to output wires. The bus bar includes, as conductive members, three external terminals connected to first ends of the windings and one Y-connection terminal for connecting second ends of the windings together. The external terminals and the Y-connection terminal are disposed on the body of the bus bar such that the Y-connection terminal and the external terminals are located on one side on the circumference of the bus bar body, whereby the bus bar body has a circumferential region where the conductive members are not present. A sensor bard carrying a position detection sensor is attached the bus bar body such that the position detection sensor is located in the circumferential region where the conductive members are not present.
