Linear Bidirectional Solenoid Actuator

Abstract

Recent Air Force contracts have identified the need for very high frequency response (700 Hz), high force level, linear actuators for use in wide bandwidth mirror positioning systems. This report describes testing performed on a linear-motion, bidirectional solenoid with a rated 52 pound continuous force capability. Testing included static force capability, linearity, heating, and dynamic force capability. Dynamic tests showed a 44:1 loss in force output from zero frequency to 500 Hz, and a phase lag of force with respect to current that increased with frequency and with input current level. These characteristics make this actuator incompatible with the requirements for the desired wide bandwidth control loop.
