Abstract

PURPOSE:To reduce the number of coils in the DC motor, simplify the construction thereof and contrive the improvement in the efficiency thereof by providing the first and second magnetic disks at both ends in rotary axial direction and auxiliary magnetic disks at the intermediate therebetween and providing coils and magnetic coupling means between the auxiliary magnetic disks and the respective magnetic disks. CONSTITUTION:The first and second magnetic disks 5, 6 having partly bent peripheral portion and main magnetic peles 5a, 6a are rotatably mounted on a rotary shaft 18. Between the first and second magnetic disks is disposed the auxiliary magnetic disk 20 made of the third and fourth magnetic disks 10, 11, which are partly bent at the outer peripheral portions to form two auxiliary magnetic poles 10a, 10b and 11a 11b. The disks 5, 6 and the disk 20 are magnetically coupled via connectors 7, 12 made of ferromagnetic material, and the first and second phase coils 9, 14 wound on coil bobbins 8, 13 respectively are so diposed as to wind the connectors 7, 12 respectively. In this manner, it can be formed to reduce the size and to be adapted for multipolar motor and contrive the improvement in the efficiency of the motor.
