Abstract
An electromechanical actuator for forced unlocking of a fuzzy jamming fault of a transmission mechanism comprises a bidirectional electromagnetic braking assembly, a circumferential rotating housing assembly, an axial spline bearing assembly, an LVDT linear displacement sensor assembly, a potentiometer linear displacement sensor assembly, and an electromechanical actuator assembly. The axial spline bearing assembly is mounted inside the circumferential rotating housing assembly for a reciprocating linear motion, and the axial spline bearing assembly is connected to an output rotating shaft of the electromechanical actuator assembly to form a spiral transmission pair; the bidirectional electromagnetic braking assembly is actively energized to generate radial and axial attraction forces, so that the circumferential rotating housing assembly is disengaged from a fixed connection with the electromechanical actuator assembly to rotate.
