A self-synchronous electrical motor comprises a rotor, a stator formed by stator windings, at least one electronic switch series-connected with a stator winding to control a mean current in the winding, a sensor of the angular position of the rotor to control the working of the switch. This electrical motor also comprises a rotating mechanical commutator or change-over switch device to shunt or route a current given by a power supply source into windings selected as a function of the position of the rotor. The commutator device is interposed in a series circuit formed by the power supply source, the stator windings and the electronic switch. Application to the industry of automobiles using electrical traction.

Self-synchronous motor and electrical traction system using a

An electrical traction system notably for automobiles which has (a) at least one recharging supply source; (b) at least one synchronous electrical motor with a stator having a plurality of spatially offset stator windings, a commutating device with choppers for routing a current given by the supply source into the stator winding in order to create a rotating magnetic field, and a rotor; (c) a circuit for charging the supply source including a transformer, which transformer includes the stator windings; and (d) at least one converter for charging an auxiliary battery.
