Abstract
An actuation system controls the flow of electric power to electromagnetic actuators to control motion or movement of at least two shafts or bodies. The system is preferentially applied to braking systems in automobiles and trucks, and may also be applied to other areas, including clutches and drive systems for other power transmission purposes. The electromagnetic retarders may also be used in combination with friction brake systems. Principal advantages of the combination system are the reliability and simplicity of friction and hydraulic components, and the lower wear and longer life of electromagnetic components.
