Abstract:
An electromagnetic retarding system, comprising:a plurality of electromagnetic retarders, each retarder operably connected to a rotating shaft; at least one sensor for measuring a quantity indicative of at least one of a speed and a torque of the shaft; a brake controller receiving inputs from the at least one sensor, the controller controllably connected to each of the plurality of electromagnetic retarders; and an electrical generator and battery for supplying power to each of the electromagnetic retarders, the means controllably connected to the controller, wherein the controller routes power to each of the plurality of electromagnetic retarders to oppose the rotating shafts connected to each retarder, and the power routed to each retarder depends on an error signal between an actual and a desired amount of at least one of a speed and a torque set by the controller for each of the plurality of retarders.
