<p>A pulsating current electromotor without commutator comprises a permanent magnet type or electromagnetic type rotor (11) keyed on a rotating shaft (12) and having the poles (14-18) diametrically opposite to one another relative to the shaft (12) on which they extend for the greater part of its circumference; the poles (15, 16) have opposite polarity with respect to one another facing a stator member (10) which is formed by a substantially cylindrical hollow body, within which the rotor (11) is arranged; formed in the stator body (10) are cavities (13) uniformly spaced from one another, each of which is arranged to contain stator double layer windings (41) which, at the outlet from each cavity (13), are directed half in a direction and half in the opposite direction; further provided are optical detector systems detecting the angular position of the shaft (12), connected to electronic piloting circuits which pilot distribution members for distributing the power to the stator windings (41) as a function of said angular displacements of the shaft (12); the components of the machine receive supply from an alternate or direct current network.</p> |
