  • Self-synchronous motor and electrical traction system using a self-synchronous motor
    Patent number: 5485064
    Abstract: 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.
