| 中文摘要: |
| 考虑三相异步电动机起动过程挤流效应对参数的影响,建立了变参数的等效电路.用函数polyfit对rn/ro=f(ξ)、Xn/Xo=f(ξ)关系曲线进行了多项式拟合,推导出计算三相异步电动机变参数特性曲线的数学模型,并用MATLAB6.5对其进行了仿真. |
| 英文摘要: |
| Considering the effect of the skin-effect during the starting of three-phase asynchronous motor on the parameter, the author sets up an equivalent circuit of variable parameter. He carries out the multinomial fitting by the function relational curve of polyfit to r n/r 0=f(ζ), X n/X 0=f(ζ), derires the mathematic model for calculating three-phase asynchronous motor’s characteristic curve and imitates the emulation to the characteristic curve of three-phase asynchronous motor with MATLAB6.5. |
