斩控式三相异步电机节能控制器的设计

Chop Controlled Three-Phase Asynchronous Motor Energy Saving Controller

本文针对三相异步电动机在轻载或空载的状态下运行时会出现的电动机功率因数变小、效率降低、电能浪费严重等问题,在分析斩控调压节能原理的基础上,提出了斩控式异步电动机节能控制器的设计方法,并对斩控式异步电动机节能控制器的主电路和PI控制器进行了设计。

For three-phase asynchronous motor running in the state of light load or idle will suffer consequences such as less power factor,lower efficient,and energy waste.The paper analyzes the theory of the chop controlled asynchronous motor energy-saving.The design of the chopping induction motor energy saving controller and the main circuit of the chopping motor controller are proposed.
