Abstract

This paper describes ways to overcome the major applicability limitations of a novel linear electromechanical actuator. Guidelines for selecting a proper soft magnetic material for a magnetic system of the actuator are presented. Conventional laminated electric steel and a soft magnetic composite material are compared based on the measured dynamic performance (up to 1000Hz) and manufacturability. A serious cross-coupling between two actuation directions of the actuator is identified and investigated. Improvements to the design are described. Experimental verification of the improved design is carried out by the two scientific groups. First measurement results show a significant (3 to 9 times) reduction of the cross-coupling
