ABSTRACT:
In the motor (1), when a drive coil (17) is wound around a salient pole (114), the opening width of an armature core (11) is kept sufficiently large to be able to wind the drive coil (17) properly and easily. After the drive coil (17) is wound, a magnetic flux collecting plate (50) including a peripheral-direction extension portion (51) and an axial-direction extension portion (52) is mounted onto the outer peripheral surface (118) of a bow-shaped portion (117) of the salient pole (114.) In this mounting operation, two pawl-shaped positioning engagement portions (55) respectively formed in the magnetic flux collecting plate (50) are fitted into grooves (119) which are respectively formed in the upper and lower end faces of the armature core (11).
