Abstract:
1. A stator for a brushless motor, comprising: a drive circuit; a bracket formed from a nonmagnetic or weakly magnetic metal plate, having a shaft support portion disposed in a central portion; a power feed terminal installation portion in an outer peripheral portion of the bracket; a brush base including a printed wiring board mounted on one surface of the bracket including conductors for a drive circuit for driving the brushless motor and a power feed terminal portion mounted on the power feed terminal installation portion; hollow armature coils mounted on the brush base, and a drive circuit component for controlling electric current flowing in the hollow armature coil mounted on the printed wiring board; the printed wiring board having a printed wiring plating trace forming a connection land providing continuity from the power feed terminal portion to lands on which said drive circuit component is mounting for effecting plating of the lands, and a separation hole cutting the printed wiring plating trace formed in the brush base after plating; and an adhesive resin applied to the surface of the brush base where the drive circuit component is disposed, the adhesive resin adhering to the bracket via the separation hole, and the brush base being thereby fixed to the bracket.
