Abstract: An apparatus for controlling force of a magnetic lead screw actuator includes a magnetic lead screw actuator, an external control module and at least one sensor device integrated within the magnetic lead screw actuator. The magnetic lead screw actuator includes an electric machine, a rotor, and a translator. The rotor includes a rotor magnet assembly forming first helical magnetic threads along the rotor and the translator includes a translator magnet assembly forming second helical magnetic threads along the translator. Rotation of the rotor by the electric machine effects linear translation of the translator by interaction of the first and second helical magnetic threads. The external control module is electrically operatively coupled to an electric machine controller of the magnetic lead screw actuator. The at least one sensor device integrated within the magnetic lead screw actuator is configured to measure a parameter indicative of a relative displacement between the rotor and the translator and this parameter is provided as feedback to the electric machine controller.
