Abstract

PURPOSE: To increase torque efficiency by arranging and providing a pair of electromagnetic coils with an electrical angle smaller than 100° against the pole pitch of a rotor which makes an opposite pole of stator teeth.
CONSTITUTION: A multipolar anisotropic orientation resin magnet rotor 1 that a plurality of magnetic poles N and S are alternately magnetized, a rotor shaft 1A, a motor supporting plate 2, a bearing plate 3 and others are provided on the peripheral surface of a steeping motor, and yoke members 5L having a plurality of stators 4 which are formed in the shape of comb line type, a core 7 on which an electromagnetic coil 6A is wound up and a core 8 similar thereto are fixed on the supporting plate 2 and bearing plate 3 respectively. Stator teeth of the stators 4 are placed within 100° of an electrical angle. According to the constitution, variations of component tolerance are absorbed by the stator teeth having a width less than 100° of the electrical angle (when P is the pitch, less than about 1/2), the forced stable point (number of calkings) can be stopped at a position equivalent to double the number of poles of the rotor 1.
