摘　　要：分析了电力拖动系统速度调节的基本技术指标。讨论了交流电动机实现变频调速的方法,指出该方法近似正弦波在较低频率下工作的不利因素,提出最低工作频率最好要高于5Hz以上。对从事变流变频调速的设计研究人员和现场维修管理的电气技术人员有一定参考价值和实用意义。This paper analyzes basic technical indicators of the electric driving system. Method for AC motor to realize variable-frequency adjustable-speed is discussed, disadvantage of this method when working at lower sinusoidal frequency is indicated, the proposed that the lowest operating frequency is better to be higher than 5Hz. It has reference value and practical significance for design researcher worked for AC variable-frequency adjustable-speed and elec- trical technician worked for on-site maintenance.

关 键 词：交流变频调速 技术指标 最低工作频率
