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.

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.

Abstract: An auxiliary device for handling failures of an actuating system of a linear electric actuator, including an auxiliary drive device which works with a braking device, so that, in case of failure of said actuating system, the auxiliary drive device returns the actuator to its zero position and the braking device maintains this position in opposition to any mechanical action.
