PURPOSE:To improve the space factor of a coil and to increase the efficiency of the stator for a motor by crossing central lines of a central hole around the hole in such a manner that equal angles are displaced, substantially perpendicularly crossing and forming pole teeth across the ends of the coil legs for the coil. CONSTITUTION:Central lines A of a central hole 1 are crossed around the hole 2 in such a manner that equal angles are displaced at 90 deg. from each other and the lines A are displaced from the center of the hole 2 in coil legs 3a-3d. Pole teeth 4a-4d of arcuate shape in plane are integrally formed to substantially perpendicularly cross at the ends of the legs 3a-3d. The teeth 4a-4d are formed at the legs at the positions slightly displaced from the center of longitudinal direction, the center line B for connecting the centers of the poles 4a, 4c or 4b, 4d pass the center of the hole 2 so as to be parallel to the line A. |
