| 摘 要： | 变频器和普通交流异步电机组成的调速系统被广泛使用,但人们还只是根据经验确定电机的最佳变频调速范围。本文通过测试普通交流异步电机在频率改变时的输出转矩转速和效率曲线,定量的研究了在频率改变时其性能的变化,在此基础上提出了交流异步电机变频调速的最佳频率范围。

| Abstract: | The system that is made from common alternate electrical asynchronous motor and inverter is extensively used. But people still certain the scope of superior frequency that common alternate electrical asynchronous motor works by experience. Author tested the curves of rotation number, torque and efficiency when common alternate electrical asynchronous motor works at different frequencies. On the base, we bring forward the scope of superior frequency that common alternate electrical asynchronous motor. |
