MICA Actuator: Highly Dynamic Controllable Magnetic Actuator

Moving Iron Controllable Actuator is a concept of linear magnetic actuator that is especially designed to respond to the need of highly dynamic controllable actuators. The article presents the specificity of the actuator compared to more classical magnetic actuator concepts. It points out the interest of its properties and describes technological issues it implies. A MICA prototype has been built and its main performances are given: 800N, 20A, with a size 160*200*150. The controllability of the actuator has been demonstrated by simulation using force characteristic of MICA. Finally, the prototype will be declined in a full range of magnetic actuators as products of Cedrat Technologies.
