POSITIONING SYSTEM FOR AN ELECTROMECHANICAL ACTUATOR

摘要

Provided is a shaft positioning system for an electromechanical actuator. According to various examples, the positioning system includes a shaft coupled to an electromechanical actuator. The shaft moves along a linear axis and the electromechanical actuator is free to translate during normal operation. An electromagnetic coil positioned around at least a portion of the shaft. The electromagnetic coil produces a magnetic field when electrical current is applied. A metal housing surrounds at least a portion of the electromagnetic coil. The shaft is placed in a predetermined position when the metal housing is in contact with a first magnet and translational motion of the electromechanical actuator is restricted when the shaft is placed in the predetermined position.
