步进电动机的最高运行频率研究

Study on the Maximum Operating Frequency of Stepper Motor

通过对步进电动机矩频特性及其运动方程式的分析,建立了步进电动机最高运行频率的数学模型,即最高运行频率为最大静转矩和负载转矩的函数.运用MATLAB软件对模型进行分析计算,得出最高运行频率和最大静转矩之间的变化关系曲线以及最高运行频率和负载转矩之间的变化关系曲线.

The mathematical model of stepper motor＇ s maximum operating frequency is established based on the analysis of stepper motor＇ s torque - frequency characteristic and systemic motion equation. The maximum operating frequency is a function of the maximum static torque and the load torque. The curve of the maximum operating frequency and the maximum static torque, the curve of the maximum operating frequency and the load torque are drawn by calculating the mathematical model using MATLAB software.
