摘要： The disclosure describes a DC motor including a rotor unit arranged within the motor body and has a cylindrical field magnet fixed to an outer surface of a holder. The holder has a rotating shaft press-fitted through the center, and the cylindrical field magnet has the S and the N poles alternately around a circumference. There is a stator unit which is circumferentially arranged around the rotor unit, that is made of a plurality of stator yokes that are arranged so that they oppose the field magnet through a small gap. Each of the stator yokes is formed by circumferentially stacking a large number of thin plates, each consisting of a salient pole, and a number of coil units, each formed by winding a magnet wire on a bobbin, and mounting the bobbins on the stator yokes. In the described arrangement, each of the S and N poles has a plurality of stages formed in an axial direction and shifted from each other in the circumferential direction by a predetermined shift amount with respect to the field magnet.

摘要： Between rotation shaft 1a and the frame 4, two bearings 5 having inner races 5b narrower in width compared with outer races 5a are disposed and each of end faces of outer races 5a is made to abut each other. Since in general, the outer race and the inner race are secured in the size precision, by making each end faces of the outer race to abut each other, an assembling precision between two bearings 5 is secured. Further, spacing secured between inner races 5b enables to displace the inner ring 5b minutely due to the preload to be given to the end face of the inner races 5b at the time of assembling of the spindle motor, which is expected to absorb a minute play inevitable to the bearings, as a result to increase the rotation precision after completion of the spindle motor.
