        Electromechanical converters (EMCs) are regarded as the most widely employed linear motion mechanism in various industry driving fields. This study tries to improve the characteristics deficiency of a moving coil electro-mechanical converter (MC-EMC), such as the output electromagnetic force, response time and response speed, and based on the time constant and currents are effected by inductance and resistance of the transformation coils, the carrying current coils of MC-EMC are adopted a transformation of segmentation and combination. The mathematical model and simulation for the response time, displacement, output electromagnetic force, acceleration of MC-EMC are proposed respectively. Results show that compared coils in parallel divided into three sections with coils in single group, the displacement step response time is reduced from 14.6㎳ to 9.94㎳ the response speed is over doubled, and electromagnetic force is raised about 8 times, the acceleration is increased by 8.7 times, the peak response time is reduced about 0.5 times, which means the design MC-EMC could realize the performance of short response time and high electromagnetic force, and display good prospects.
