And according to the mathematical model, vector control principle and minimal direct axis current control and its digital realized method were discussed.
结合数学模型,讨论了有关矢量控制的原理和直轴电流最小控制的数字实现方法。
Then the variation of direct axis and quadrature axis inductances was obtained by 3D finite element method for the taper permanent magnet motor with the taper rotor at different axial locations.
