This paper reports the study on manufacturing technology of a brushless DC motor for saving energy with high efEciency. This motor hae a joint-lapped core which is able to warp for the reverse fieely. First, the joint-lapped core is formed with the high-speed press Inachine by cyhndrical shape. In coil winding, the joint-lapped core is warped for the reverse by bending the joints and wound the coil under the condition of the alignment. After winding, the joint-lapped core is bent as a similar conventional circular stator. This Inanufacturing method brings the coil of the high density by using the tbick magnet wire and the stator of a high degree of a right circle. As a result, it can be realized the efficiency of 96% of the motors in the compression machine for the air conditioner.
