PURPOSE: A copper loss reduction type drive motor is provided to increase a saturation magnetic flux density and a counter electro-motive force in the entire region and increase efficiency by increasing a coil width thickness together according to a width thickness. CONSTITUTION: A core teeth(1) increases gradually toward outside. The width thickness of a coil space(2) gradually increases from a center to the outside. At least one coil(11,12,13,14) is reeled without a dead space. A coil is laminated with each other in a reeled state. |
