Abstract
A method for forming an electromechanical actuator that involves using at least one motor module engageable with an output ram for controllably translating the output ram along a linear axis of the output ram. A torque sensing adaptive control (TSAC) system is used for monitoring motor module torque within the motor module and generating a disengagement command signal. The disengagement command signal is used to initiate disengagement of the motor module from the output ram when the torque within the motor module is outside an allowable motor module torque range.
