In order to apply the electromechanical actuator to tactical mini-missiles  maximum rotational speed of output shafts is greater than 250/s. Test results basically correspond to the requirement of technical indexes. It is proved that this analysis and design method is congruent with the design of micro-electromechanical actuators  this paper researches on the key technology such as load-bearing ability  the system bandwidth can reach 25.3Hz on the condition of no load and 23.4Hz on the condition of load  thus the method is feasible. 2010 IEEE.  rapidity and miniaturization of the micro-electromechanical actuator power system based on the ball screw. First  according to specific technical indexes  the power  electromechanical time constant and the size of the motors are screened originally through theoretical analysis. Finally  based on the characteristics of ball screw transmission  load locus of the micro-electromechanical actuator dynamic system is theoretically analyzed and the optimum speed ratio is determined through parameter optimization. The results of the double closed loop controlled test on the principle prototype show: the system can operate normally with 2.5N.m hinge moment
