Abstract:
1. A motor for electric power steering, said motor having a stator, and a rotor which is rotatably supported and disposed opposite to said stator with a gap between the rotor and the stator; wherein: said stator comprises, a stator core; multi-phase stator coils assembled in said stator core; and an electrical connection apparatus electrically connected to said stator coils and supplied with electric power from the exterior; said electrical connection apparatus comprises, a first wiring member for connecting respective phases of said stator coils; and a second wiring member supplied with electric power from the exterior; said first wiring member and said second wiring member are stacked in an axial direction of the motor and electrically connected to each other; an annular base formed of an insulating member; and a plurality of flat plate conductors connecting said stator coils per phase and fitted into said annular base said plurality of fiat plate conductors have the same shape, and comprise, a first circular-arc conductor disposed in an inner peripheral portion of said annular base; a second circular-arc conductor disposed in an outer peripheral portion of said annular base; and a connecting conductor connecting one end of said second circular-arc conductor and one end of said first circular-arc conductor to each other; said first circular-arc conductor and said second circular-arc conductor for different phases being disposed in said annular base in radially opposed relation.
