Abstract:
1. A method of manufacturing a stator unit for an electronically powered motor which includes a base portion and a rotor rotatably supported via a bearing mechanism around a center axis, comprising: a) a step of preparing a stator core having a plurality of teeth, radially arranged with centering on the center axis and connected to one another so that relative positions of those teeth are fixed; b) a step of preparing a terminal having a plurality of terminal pins, radially arranged with centering on the center axis in a manner so that relative positions of those terminal pins are fixed; c) a step of placing the stator core and the terminal approximately coaxially with an axial interval therebetween; d) a step of forming a coil by winding a wire around each of the plurality of teeth; e) a step of electrically connecting wires led from the plurality of teeth to the plurality of terminal pins; and f) a step of bringing the terminal close to the plurality of coils by moving the terminal relative to the plurality of coils along the center axis, wherein the method further comprises a step of preparing a guide portion axially extending with centering on the center axis, wherein the stator core and the terminal are arranged along an outer side face of the guide portion in the step c), and the terminal is moved along the outer side face of the guide portion in the step d).
