  • Patent number: 10480628
    Abstract: An electric actuator to be primarily used on an all-terrain vehicle (ATV) having implements such as snow plow is disclosed. The main purpose of the actuator is to allow the driver to rotate the blade when it is not touching the ground without having to get out of the vehicle. The actuator is composed of a stator assembly and a motor assembly. An electric motor is concealed in the motor assembly and drives a screwed or grooved part that engages the threaded or grooved inner surface of the stator assembly. Rotation of the screwed or grooved part induces a translational movement alongside the longitudinal axis of the actuator assembly. The translation movement induces the elongation or the retraction of the actuator depending on the rotating direction of the electric motor.

  • Publication number: 20150042191
    Abstract: This invention generates electric power from the rotational motion of the braking system of wheeled vehicle having brake rotors. As the brake rotor, comprised of conducting surface regions and non-conducting surface regions rotates, a magnet, which is disposed in close proximity to the brake rotor's conducting and non-conducting surface regions, generates an electric current to provide electric energy to a energy supply device, typically a battery.

  • Patent number: 8878466
    Abstract: An electro-mechanical linear actuator unit comprising an actuator housing that accommodates at least two electric drives, each of which, when actuated by a control device, sets an associated drive of a respective spindle drive into rotation for adjusting linear movement of the associated spindle drive in order to produce relative linear adjustment of a control rod. The two electric drives are located in the actuator housing in such manner that relative adjustment can be produced by simultaneous actuation of the two electric drives, as the sum of the adjustment movements of the associated spindle drives, or by actuating a single electric drive, as the adjustment movement of the associated spindle drive. A respective brake is provided, in an area of each of the two electric drives, which can be selectively actuated by the control device to then prevent the adjustment movement of the respective associated spindle drive.

  • Patent number: 8857578
    Abstract: A magnetic brake has an outer stator surrounding an inner stator with a circumferential slot between the outer stator and the inner stator. A coil is provided in the inner stator adjacent to the circumferential slot. A drag plate is attached to a rotatable shaft extending centrally through the inner stator. A drag ring joined to the drag plate extend into the circumferential slot. The drag ring may be an annular cylindrical ring section separate from the drag plate. Vent holes pass through the inner stator adjacent and parallel to the shaft. The magnetic brake uses both hysteresis and eddy current braking.
