This paper introduced working principle of dual-coil self-sensing actuator based on magnetically controlled shape memory alloy (MSMA). The ANSYS software was used to establish the finite element model of MSMA dual-coil self-sensing actuator. Edge element method was adopted to analyze the MSMA dual-coil self-sensing actuator's 3-D static magnetic field under the influence of different excitation voltages. The analysis obtained MSMA and silicon steel sheet distribution of magnetic induction intensity and the magnetic field intensity, has further confirmed the reliability of MSMA dual-coil self-sensing actuator, and has given the MSMA length relations along with the magnetic induction intensity changes. The results show that magnetic field analysis has certain reference value to the MSMA practical application.
