PURPOSE:To permit fine torque control by a method wherein the turns of an upper coil mounted on an iron core is made to differ from the turns of a lower coil mounted on the iron core, and the number of series connected conductors is made an odd number to obtain the characteristics of the middle turns. CONSTITUTION:The winding starting and X and the winding finishing end Y of a coil 36 wound on the slot of an iron core 32 are made to appear at the opposite sides of the iron core 31 respectively. Namely, the turns of the upper coil 36a has one more turn than the turns of the lower coil 36b to make the series number of conductors for one coil 36 an odd number. In this way, for example, when the upper coil 36a and the lower coil 36b have 5 turns and 4 turns respectively, the characteristics corresponding to a middle turn of 4.5 can be obtained, and fine torque adjustment can be done for small turns. |
