PROBLEM TO BE SOLVED: To provide a motor where the downsizing and thinning can be achieved and also the reliability is improved, by suppressing the height of a coil end to be low, and a method of manufacturing the motor. SOLUTION: The axial sectional form of the wound part 7a of an insulator 7 covering a pole tooth 8 is constituted to form approximately a parallelogram where the thickness of the insulator for the amount of the spaceΔG which arises by inertia when a winding nozzle shifts from a rectilinear track to a circular track is reduced, whereby even if the winding speed of the winding nozzle is increased, the winding form after winding of a drive coil 2 can be made roughly rectangular, so the height of a coil end projected axially from a stator iron core can be made low. Therefore, a thinned motor can be obtained. Moreover, since the peripheral length of a coil can be shortened, an efficient motor by the reduction of copper loss can be obtained. Moreover, since the winding speed can be increased, processing cost can be reduced. Therefore, the cost reduction of the motor can be achieved. COPYRIGHT: (C)2005,JPO&NCIPI
