PROBLEM TO BE SOLVED: To provide a coil winding device 1 of a multipolar armature 2 capable of winding the coil position accurately at high speed.SOLUTION: The coil winding device of a multipolar armature includes a nozzle 6 for feeding a wire rod for winding, a nozzle axial direction drive mechanism for driving the nozzle 6 in the central axis direction of a ring-shaped yoke 3, and a yoke drive mechanism for rotating the yoke 3 about the central axis thereof. The nozzle axial direction drive mechanism includes a belt 8 which moves the nozzle 6 attached thereto in the central axis direction of the yoke, a reduction gear 12 having an output shaft connected with one of pulleys provided at both ends of the belt 8, and a drive motor 11 connected with the input shaft of the reduction gear 12 where the variable range of response frequency contains the natural frequency of the belt. |
