摘　　要：对永磁交流伺服精密驱动系统进行动力学分析时,必须考虑系统的机电耦合影响。从机电能量转换的角度,根据系统的全局耦合分析和局部耦合分析,建立了该系统全局耦合关系图和永磁同步电动机精密传动装置子系统局部机电耦合关系图,然后采用拉格朗日麦克斯韦方程建立了永磁同步电动机精密传动装置子系统的物理模型和数学模型,推导了该子系统的动力学方程,并利用该模型进行了算例分析。结果表明,该模型是正确的,这为该系统的实验研究提供了理论依据。Electromechanical coupling effect is considered in the dynamic analysis on permanent magnet AC servo precision derive system. Using electromechanical energy conversion and according to the global coupling analysis and the local coupling analysis, the relation diagrams of global electromeehanical coupling and local electromeehanical coupling between the permanent magnet synchronous motor-precision transmission subsystem are established. Applying Lagrange-Maxwell equation, a physical model and a mathematic model of the subsystem are built up, the dynamic equations of the subsystem were derived, and the mathematic model is analyzed. The results show that the mathematic model is correct which provides theoretical basis for experimental study.
