给出处理电机的计算机辅助设计中出现的具有一个参数的曲线族f(λ,X)的插值计算问题的一种方法.结合电机的磁饱和问题实例,给出了Baisc程序。为了减少曲线列表的人为误差,提出了磁饱和问题在计算机上处理的另一种方法及其Basic程序。实际计算证明,后一种方法是简单易行、有效的方法. A method to solve the interpolation calculation of a family of curves f (λ, X) with one parameter appearing in the computer aided design of the motor is given. The Baisc program is given in connection with the example of the magnetic saturation of a motor. In order to reduce the man-made error of the curve list, another method of magnetic saturation problem processing and its Basic program are proposed. The actual calculation proves that the latter method is a simple and effective method.
