An electromechanical regenerative retarder device 1 comprises a frame 2, a first retarding portion on one side of the frame and a second retarding portion on the other side of the frame. Each retarding portion comprises a stator/rotor pair 3, 6, where the stator is arranged to generate a movable magnetic field and where the relative speed at which the magnetic field moves relative to the rotor is adjustable. The regenerative retarder may be operated either as an induction motor to drive or assist in driving an appliance (e.g. a vehicle), or as a regenerative braking unit, where the modes of operation are effected by adjusting the relative speed at which the magnetic field moves relative to the rotor. In an embodiment, the regenerative retarder may be mounted in a vehicle in place of a conventional centre bearing for the vehicles prop shaft, with prop shaft sections fixed to the rotors such that the rotors can drive, or be driven by, the prop shaft. The retarder may be connected to a supercapacitor unit. The device may be used as a retarder for a vehicle, fitted to its propeller shaft, and to apply resistive torque in machines such as exercise bicycles, rowing machines, dynamometers, winding gear, elevators, winches, ski lifts or cable car systems. |
