High-performance moving-coil actuators with double-sided PM arrays: A design comparison

The paper describes the modeling and design of actuators for application in a magnetic vibration isolation system with passive gravity compensation. Parallel to the fully passive magnetic gravity compensation these actuators provide the stability and active isolation required in such a 6 DoF vibration isolation system. Powerful analytical modeling techniques are used to accurately derive the key properties of the actuator and to compare different topologies with and without back-iron, respectively.
