ABSTRACT:
A 1-phase brushless motor comprises a single position-detecting element located at a stationary position corresponding to a magnetically active conductor portion of an armature coil of an armature member. The position-detecting element is either a magnetoelectric transducer or a position-detecting coil. A plastics magnet is molded integrally with the armature coil and is magnetized such that it cooperates with a field magnet as a rotor to generate a field magnet attracting and repulsing torque within a particular range from a dead point, so as to stop the field magnet at a position from which the motor can start itself.
