  • Patent number: 7643914
    Abstract: A method for controlling a drive assembly of a vehicle including applying a conduction angle set value greater than 180° to a variable reluctance machine such that the machine operates in a continuous current mode adjustable according to the controlled measurement of operation stability of the machine in the continuous current mode.
    Type: Grant
    Filed: October 27, 2005
    Date of Patent: January 5, 2010
    Assignee: Renault S.A.S.
    Inventors: Serge Loudot, Armando Fonseca
  • Patent number: 7535143
    Abstract: An electromagnetic coupler for a motor vehicle. The coupler includes a first electric machine having an axis and including a first stator bearing a first coil, an input rotor and a first part of an output rotor, and a second electric machine including a second stator bearing a second coil and a second part of the output rotor. The input rotor includes an inner drum spaced apart from the first part of the output rotor and from the first yoke, while the second yoke is spaced apart from the second part of the output rotor by an air gap. The first coil is wound onto the yoke of the first stator around the axis of the first electric machine.

  • Publication number: 20070164628
    Abstract: An electric transmission, in particular for a motor vehicle, including two electric motors, whereby the shaft of one of the electric motors is connected to a mechanical energy source, the motor converts mechanical energy into electrical energy, the other electric motor converts electrical energy into mechanical energy, and the shaft thereof is connected to the element to be driven. Rotors of both motors are arranged concentrically or axially in relation to each other, and both rotors cooperate with stators, the windings of which are arranged inside the volume defined by both rotors. The windings include several annular windings juxtaposed in volume, the windings being supplied with alternating currents which are out of phase in relation to each other.
