Abstract

There are a wide range of potential applications of magnetically shape memory alloy (MSMA) actuators in high force positing systems. This paper makes an investigation in the structure and control strategy of MSMA actuators based on the experimental study on the control properties of MSMA material. The structure, operation principle and control strategy of three kinds of linear MSMA actuators are discussed. They are the basic linear MSMA actuator, the differential linear MSMA actuator and the inchworm type linear MSMA motor. Besides, a new type of rotating MSMA actuator is introduced. The feasibilities of all the introduced MSMA actuators have been proved by the prototype machines.
