摘要
两自由度直驱感应电机满足特殊场合的需求,其轴端可输出旋转、直线或螺旋运动。针对两自由度直驱感应电机多运动形式的耦合性造成对其特性分析具有一定困难,通过建立两自由度直驱感应电机的简化模型,利用麦克斯韦方程组建立旋转运动与直线运动之间相互影响的运动耦合数学模型,并对两自由度运动耦合影响进行定性分析;建立了两自由度直驱感应电机的三维有限元参数化模型。通过对电机在不同运行状态下进行仿真分析进行验证,结果显示旋转运动对直线运动存在一定的削弱影响,而直线运动对旋转运动影响则很小。说明所建立的运动耦合数学模型的合理性和可行性,对于旋转-直线电机的理论研究和应用具有一定的参考价值。
Two degrees of freedom（ 2-DOF） direct-drive induction motor meets the needs of special occasions,the shaft end of which can implement rotary,linear and helical motion. The multi-forms of motion of 2-DOF direct-drive induction motor made it difficult to analyze the characteristics. In this paper,motion coupling mathematical model of 2-DOF direct-drive induction motor was established by using Maxwell equations. The motion coupling effect between rotary motion and linear motion was analyzed qualitatively. Three-dimensional parameterization finite element model of 2-DOF direct-drive induction motor was established. Then the motor in different operation state was simulated which shows that motion coupling effect between rotary motion and linear motion is manifest as the weakening influence of rotary motion on linear motion. However,the influence of linear motion on rotary motion can be ignored. The rationality and feasibility of the established coupling mathematical model can also be confirmed. It has some reference values to theoretical research and application of rotary-linear motor.
