In order to reduce the influence of temperature on the operating performance of the macro and micro drive, a double-wounding circulating water cooling structure is proposed. Based on the law of thermal resistance, the heat transfer model of the macro and micro drive forced convec-tion cooling was established, and the influencing factors of the internal temperature distribution of the macro and micro drive system were analyzed. And the macro to micro drive forced con-vection cooling when the macro dynamic system part of the output force, and the size of the output displacement and micro system of the rise of temperature of the giant magnetostrictive material (GMM) and output displacement simulation and experiment, the results show that when the circulating water flow rate is more than 3 m/s, macro to micro drive internal temperature decreased significantly, the macro dynamic range at around 1 N. The fluctuation range of macrodynamic output displacement is between 0~20 μm. The error of output displacement gen-erated by the micro-motion magnetostrictive rod is less than 1 μm, at this time, the temperature change has little influence on the output force, output displacement and micro output displace-ment of the macro-moving part.
