Abstract
A stator of a brushless motor is disclosed which includes a stator core, an insulating frame arranged on the stator core, and a plurality of windings wound around the insulating frame. The stator core includes a ring-shaped yoke part and a pole part mounted to the radial inner side of the yoke part. The pole part includes a plurality of teeth spaced-apart from each other along the circumferential direction, and a ring-shaped portion arranged at and connected to the radial inner side of the teeth. The radial outer sides of the teeth abut against the radial inner side of the yoke part. The insulating frame is arranged on the pole part. A plurality of power terminals are fixed to one axial end of the insulating frame and respectively electrically connected to the windings.
