  • Rotor of an electric motor, with an outer sleeve formed by winding, method for producing such a rotor, and electric motor comprising such a rotor
    Patent number: 9793771
    Abstract: An electric motor rotor including a magnetic core, magnets fastened to the periphery of the magnetic core, and a wire wound with touching turns around the magnetic core and the magnets. The wire includes a metal core surrounded by an electrically insulating layer, itself covered by an outer sheath of thermo-adhesive material, the turns being fastened to one another by adhesion between mutually contacting portions of the outer sheath. A method of fabricating such a rotor. An electric motor including such a rotor.
    Type: Grant

  • Actuator having a multiphase motor, and a method of controlling such an actuator
    Patent number: 8957621
    Abstract: An actuator comprising at least one multiphase motor having phases facing a rotor secured to an outlet shaft associated with a braking member and provided with a connection to a movable element that is to be moved, the motors and the braking member being connected to at least one motor control unit for controlling the motors by powering their phases. The motor has at least four phases wound in such a manner as to avoid a neutral point, and in that the control unit has one single-phase inverter per phase and is arranged to implement a nominal, three-phase mode of control, and a degraded mode of control that enables the rotor to be driven in rotation by powering two non-collinear phases thereof.
