PROBLEM TO BE SOLVED: To provide a motor that improves heat dissipation while maintaining insulation property by forming an insulating layer between a coil and a frame, and a method of manufacturing the same. SOLUTION: A concentrated winding coil wound to be stored in the tooth of a single-slot core, is molded with high heat-conductive resin, and insulating layers are formed at both ends of the molded coil. The molded coil is fitted in a stator core with an open slot. The first frame and the second frame for a motor divided into two, are pressed against the end faces of the molded coil from both sides, to bring the insulating layers of the molded coil into contact with the frames. The heat dissipation can be improved while maintaining the insulation property of the motor, by forming insulating layers at both ends of the concentrated winding coil molded with high heat-conductive resin and bringing the insulating layers of the molded coil into direct contact with the frames.
