Abstract

PURPOSE:To increase the output torque of an apparatus during rotation and improve the efficiency thereof by setting the circumferential width of a magnetic pole under given conditions. CONSTITUTION:A coil is wound round a core 21 via an insulator to constitute a stator which has four magnetic poles 20a, 20b. Said magnetic poles 20a, 20b respectively spread circumferentially in tip to be formed into almost T-shapes, and the circumferential widths alpha, beta of the tips of the magnetic poles 20a, 20b are respectively set to almost 180 degrees and 140 degrees of electrical angle. Further, the central angle gamma between central lines in the circumferentially adjacent magnetic poles 20a, 20b is set to almost 170 degrees electrical angle.
