    摘要： A stator (20) of a brushless motor is disclosed which includes a stator core (70), an insulating frame (80) arranged on the stator core (70), and a plurality of windings (60) wound around the insulating frame (80). The stator core (70) includes a ring-shaped yoke part (71) and a pole part (72) mounted to the radial inner side of the yoke part (71). The pole part (72) includes a plurality of teeth (73) spaced-apart from each other along the circumferential direction, and a ring-shaped portion (74) connected to the radial inner side of the teeth (73). The radial outer sides of the teeth (73) abut against the radial inner side of the yoke part (72). The insulating frame (80) is arranged on the pole part (72). A plurality of power terminals (61, 62, 63) are fixed to one axial end of the insulating frame (80) and electrically connected to the windings (60).
