摘要
运用电力拖动的原理，以电风扇为例，分析了鼠笼式电动机一一通风机系统采用降电压法调速运行的原理、性能及技术措施，探讨了通风机系统降电压调速技术应用的现实意义。
Based on the principle of electrical engineering and taken an electric fan as an example, the principle, properties and technique methods of a squirrel-cage motor driven ventilating system are systematically analyzed by voltage step-down and the realizability of step-down speed adjusting in power supply system is also discussed.
