“平面圆图”在电机仿真中的应用

Application of "Polar Graph" in Numerical Simulation of Electrical Machines

提出了用“平面圆图”输出电机动态性能数值仿真波形的新方法．该方法在极坐标上以动画方式输出仿真结果，较之传统的ｘｙ平面直角坐标系，其突出优点是能够显示更大时域范围的仿真信息．文中结合ＡＬＡ转子电机仿真实例对这种方法加以说明．

A new method to display simulation results of electrical machines by using 'Polar graph' is proposed. The real-timed waveform is plotted in polar coordinate on screen continuously. Compared with the traditional way, this method can display the results with a longer time domain. As an example, the dynamic performance of an ALA rotor machine is investigated.
