Abstract:
A small-sized motor for electric power steering, in which coil connection can be easily performed with space saving, and a method for manufacturing the motor. Multi-phase stator coils assembled in a stator coil are connected per phase by connecting rings at coil ends of the stator coils. A bus bar supplied with electric power from the exterior is stacked onto the connecting rings in the axial direction of the motor and is electrically connected to the connecting rings.
