Abstract
A shaded pole motor includes a squirrel-cage rotor and a stator assembly. The stator assembly having a bore for rotatably receiving the rotor and pole separation parts on an inner circumference of the bore so that adjacent separated portions are excited alternately to an N-pole and an S-pole when a winding is energized. The inner circumference of the bore is divided into plural sections represented by 2(2n+1). The magnetically divided two pole portions have pole sections having an alternating N-pole and S-pole, and non-pole sections, when a winding of the stator is energized.
