Abstract

Improvements in direct current electrical machines without collector, of the type consisting of a rotor that is the seat of a constant magnetic field directed according to at least one diameter of the rotor and produced either by a permanent magnet or by a coil covered by a constant direct current, and a stator provided with a polyphased winding, the winding of each phase being linked to the direct current source or straightened by at least one electronic commutator controlled by an angular position sensor driven by the rotor shaft, characterized by the fact that the set of electronic switches and their connections with the windings of the different stator phases is organized in such a way that each one of the shed current emissions with respect to each other has an angle corresponding to the number of the phases, it has an amplitude that increases and then decreases due to low value increments r in order to present an almost sinusoidal aspect, and that the windings of the different phases of the stator are connected to each other in a star and distributed over the sector in such a way as to give rise, when its power supply by outdated current emissions variant by increments, to a rotating field of appreciably constant value.
