Patent ID: 8018104

Claim:
An electric power steering motor having a stator, and a rotor rotatably supported and disposed opposite to said stator with a gap left therebetween; wherein said stator comprises: a stator core; multi-phase stator coils assembled in said stator core; and a wiring component electrically connected to said stator coils and supplied with electric power from an exterior, said wiring component comprising a first wiring member for connecting said stator coils per phase, and a second wiring member supplied with electric power from the exterior; wherein said first wiring member comprises a plurality of flat plate conductors; said second wiring member comprises a plurality of flat plate conductors; said first wiring member and said second wiring member are stacked in an axial direction of the motor, and are electrically connected to each other, thereby forming a wiring connecting portion in an axially stacked multi-layered structure; said first wiring member comprises, 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; and said plurality of flat 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.
