Abstract
A stator of a motor having various shapes and capable of minimizing the manufacturing costs. At least teeth are manufactured by the iron powder metallurgy method. In order to obtain the overhang effect, the height of a tip of each tooth is lower than the height of a rotor and the height of a yoke is higher than the height of a tip of each tooth so as to minimize the core loss of the yoke. Since, in order to minimize the end coil, the height of a neck of each tooth is gradually higher as running from the sides to the central portion in the circumferential direction, costs for manufacturing a motor can be minimized and sufficient efficiency can be obtained.
