ABSTRACT:
The pulsating current brushless electric motor includes a permanent magnet rotor rotating in a stator and having numerous circumferentially adjacent polarities in corresponding opposition. The stator contains slots positioned at a uniform reciprocal distance from the pertaining field windings. The rotor performs a keyed rotation on a particular shaft which includes known optical, magnetic or similar devices for the operational detection of its angular position, in combination with electronic circuits which are preset to the distribution of the electric current in the windings.
