椭圆驱动超磁致电动机设计

超磁致材料GMM(Giant Magnetostrictive Material)作为高科技功能材料得到了迅速发展，由于具有大的室温超磁致伸缩系数，高的电(磁)能．机械能转换率，高能量密度，响应快等优异特性，GMM得到了广泛应用。文中根据GMM磁-机能量耦合转换机理，结合有限元分析开发了CAD软件，设计了GMM微致动器，并通过GMM致动器组合构型，构思与研制了一种具有高出力、快响应、可控性好的新型椭圆驱动超磁致电动机，并得到了试验验证。

DESIGN FOR ELLIPSE MOTION DRIVEN MOTOR MADE OF GIANT MAGNETOSTRICTIVE MATERIAL

Giant magnetostrictive material (GMM) is developing rapidly.It is widely applied owing to its good quality in room temperature such as giant strain coefficient,efficient electric (magnetic)-mechanic translation ability,high energy density,and quick response.In this paper,CAD software based on finite element method was firstly developed.An actuator of GMM according to the magnetic-mechanic coupling translation was designed.Then through the assembling of two GMM actuators in the principle of ellipse motion a new motor is developed,which appears with large output forces,quick response and excellent controllability.At the end the experimental validation of the ellipse motion produced by the assembled motor,was shown.
