【摘要】 本文通过对电流型变频器供电的同步电动机状态空间的分析,导出了用以确定同步电动机步进运动时稳态运行的精确方程。这些方程以转子磁链为状态变量,消除了对阶梯电流求导的困难。利用这些方程,可以分析同步电动机稳态运行的各种特性,并可方便地分析同步电动机的动态特性。本文采用数字求解,并用所得出的状态空间模型对同步电动机步进运动的稳态特性进行了仿真研究。更多还原

【Abstract】 In this paper, the state-variable equations of synchronous motor on step motion which are used to describe steady -state characteristics are developed by state space analysing to synchronous motor with current type converter. To select rotor linkages as state variables, the difficulty of derivation to stepping sinusoidal current is solved. These models have been developed to analyse steady - state and also dynamic characteristics conveniently. The solutions are found by computer and the steady -state characteristics of synchronous motor on step motion are simulated and analyzed by using these state space models.更多还原
