<p>A stator of a motor having various shapes and capable of minimizing the manufacturing costs. At least teeth (60) are manufactured by the iron powder metallurgy method. In order to obtain the overhang effect, the height (62H) of a tip (62) of each tooth (60) is lower than the height of a rotor (50) and the height (70H) of a yoke (70) is higher than the height of a tip of each tooth (60) so as to minimize the core loss of the yoke (70). Since, in order to minimize the end coil, the height (64H) of a neck (64) of each tooth (60) is gradually higher as running from the sides (64a and 64b) to the central portion (64c) in the circumferential direction, costs for manufacturing a motor can be minimized and sufficient efficiency can be obtained.</p> |
