Abstract: A electromagnetic device may include a core in which a magnetic flux is generable and an opening through the core. A primary conductor winding may be received in the opening and extend through the core. A primary electrical current signal flowing through the primary conductor winding generates a magnetic field about the primary conductor winding and a first magnetic flux flow in the core. A secondary conductor winding may be received in the opening and extend through the core. A first modular conductor winding may extend through the opening and encircle a first outer core portion of the core. A first modulation signal flowing through the first modular conductor winding modulates the primary electrical current signal to provide a modulated output current signal at an output of the secondary conductor winding.

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.
