Abstract
PURPOSE:To reduce the number of parts and to perform the self-starting of a commutatorless motor by providing N-pole and S-pole magnets on the inner periphery of a rotor to be displaced in one direction, forming a position detecting window and providing stator poles wound with coils. CONSTITUTION:An interrupting part 25 and a window part 26 are formed at an angle of 180 deg.C, for example, at the lower part of a rotor 2, and N-pole and S-pole magnets 21, 22 radially magnetized at an angle of 120 deg. are so formed as to be displaced symmetrically in one direction with respect to the central line for coupling the boundary between the interrupting part 25 and the window part 26. Stator poles 11, 13 wound with driving coils L1, L2 and stator poles 12, 14 wound with no coil are alternately opposed to form a stator 1. Any of the coils L1, L2 is selectively excited to become the same polarity depending upon the position signal of the rotor 1 from position detecting means formed, for example, of a light emitting diode 31 and a phototransistor 32, thereby rotating the rotor 2.
