PROBLEM TO BE SOLVED: To provide a motor which is prevented from generation of cogging and enhanced output level, by improving structure of rotor to easily wind a driving coil in a maximal condition, and increasing functions to collect magnetism. SOLUTION: In a motor, the opening width of an armature core 11 is made sufficiently wider at the time of winding a driving coil around a salient pole 114 so that the driving coil may be wound easily in an appropriate state. After the driving coil is wound, a magnetism collecting plate 50 provided with peripheral projecting sections 51 and axial projecting sections 52 is attached to the outer peripheral end face 118 of an umbrella section 117. At the time of attaching the plate 50 to the end face 118, pawl-like positioning and engaging sections 55 of the plate 50 are put in grooves 119 respectively formed in the upper and lower end faces of the armature core 11. |
