ABSTRACT:
A radial gap type cylindrical motor structure including a rotor which has a field magnet 13, a stator poles 20 having salient poles 18 opposed to the field magnet 13 of the rotor, a magnetic flux density adjusting yoke 21 formed in a cylindrical shape using a soft magnetic material and having salient poles 18, half the number of salient poles being projected as upper salient poles on an inner upper edge of the yoke inwardly at an equal angle and the remaining half of the salient poles being projected as lower salient poles on an inner lower edge of the yoke inwardly at an equal angle so as not to overlap the upper salient poles vertically, and driving coils 12 wound respectively around the upper and lower salient poles.
