ABSTRACT:
A single-phase step motor comprises a stator having a coil and a magnetic circuit composed of a core and a plate having a hole in which is disposed a rotor equipped with a permanent magnet. The plate has a slot in the area of the hole, whose width and the position of the axis line thereof are determined by the magnetic asymmetry of the stator poles, sufficient to produce required driving and positioning torques of the motor.
