Abstract

Improvements in electric motors, asynchronous or stepper operation, governed by single-phase bidirectional or biphasic unidirectional impulses, of given cyclic ratio, which allow, more particularly, to provide a high starting torque with small volume and to determine in a simple way, the direction of rotation of the mobile part, characterized in that it comprises a stator composed of two similar elements, coaxially mounted one above the other, so that its pole pieces, consisting of a main rectangular tooth and at least one additional surface of equal polarity that the main surface be located at the same height and that their relative orientation allows the pieces to alternate on the periphery of the assembly to cooperate with a coaxial rotor, consisting of a cylindrical multipole magnet whose pores are equidistant and, characteristically, in helicoid shape, centered on each of the pole pieces .
