Abstract

The outer-rotor type brushless DC motor (9) has a stator core (1, 81, 112) around which a coil is wound, a shaft (3, 121) fixed to the central position of the stator core (1, 81, 112), a bearing (4a, 4b) whose inner ring is fixed to the shaft (3, 121), and rotor yoke (5, 80) fixed to an outer ring of the bearing (4a, 4b). Rotor yoke (5, 80) has a plurality of magnets (6, 82) on its inner- circumference plane that faces the stator core (1, 81, 112) in a circumferential direction. Further, the brushless DC motor (9) has first holding ring (10a, 20a) having protrusion (14a) at an upper section of the shaft (3, 121) in the axial direction and has second holding ring (10b, 20b) having protrusion (14b) at a lower section of the shaft (3, 121) in the axial direction. Protrusion (14a) holds an upper end of magnets (6, 82) in the circumference direction, while protrusion (14b) holds a lower end of magnets (6, 82) in the circumferential direction.
