Abstract
The invention provides a system, device and method for using a rotary actuator, e.g., a stepper motor to actuate a wrap spring clutch. Feedback from a system of sensors and GPS data, including rotational speed, travel speed and direction are provided to improve the reaction accuracy of the clutch. In one embodiment, a plurality of actuator controllers are connected in a configuration wherein one controller is a 'master' and the remaining controllers are 'slaves' to provide a higher level of machine control.
