已建立起一种用计算机来确定永磁磁路最佳设计的方法。这种方法包括寻找磁路的等值电路并编写出计算各种不同电路单元的计算程序,求解所得到的网络方程式,计算漏磁与磁阻系数,并且用反复迭代的方法求解这些设计方程,以满足最小磁钢体积、最低材料成本等设计原则。此程序同样可以用来计算某一给定设计方案的预期性能,这就允许设计者在不需要制造样机的情况下,判断他的设计思想。完成上述过程的时间仅为几秒钟,同时设计者可以用“设计者(?)计算机”,这样的“相互作用”的方式来使用此程序,这就可以显著地节约设计时间。 A computer-based method has been established to determine the best design of PM magnetic circuit. This method includes finding the equivalent circuit of the magnetic circuit and compiling a calculation program for calculating various circuit units, solving the resulting network equation, calculating the magnetic flux leakage and the magnetoresistive coefficient, and solving the design equations by iterative methods, To meet the minimum magnet volume, the minimum material cost and other design principles. This procedure can also be used to calculate the expected performance for a given design, allowing designers to judge his design without having to build a prototype. This process is completed in just a few seconds, and designers can use the program in a “designer (?) Computer”, “interacting” way, saving significant design time.
