PURPOSE:To facilitate an assembly by dividing main-coil cores and auxiliary- coil cores in two respectively, by forming only one slit inside each core, by winding coils round the cores laminated in plural, and by forming later the main core and an auxiliary core. CONSTITUTION:Main coil cores 18a and 18b and auxiliary-coil cores 19a and 19b, which are divided in two respectively, are formed so that their insides are shaped to be nearly semi-circular-arc and the same with each other. Only one slit 21 is formed inside each of these cores 18a, 18b, 19a and 19b. A plurality of cores are laminated, and coils 22a, 22b, 23a and 23b are made between the slits 21 of the cores 18a, 18b, 19a and 19b and the outside. Unit cores whereon the coils 22a, 22b, 23a and 23b are wound are placed by two opposite each other, thereby the main core and an auxiliary core are formed, and these are superposed on each other in the axial direction. |
