Abstract

The magnetically controlled shape memory alloy (MSMA) is a new type of functional materials, which has large strain and high efficiency of electromechanical energy conversion. In this paper, the work principle of the MSMA linear actuator is introduced, and based on the analysis and design on magnetic circuit and winding, the dynamic model of MSMA actuator and the simulating curves are given. After the control system is designed, the MSMA actuator prototype is proposed. The experimental results verify the model´s validity and practicability of MSMA in intelligent system.
