摘要
介绍了一种电机保护控制器的设计方案。该控制器可用于检测三相电中的电压电流信息,并对异常现象作出及时的反应和动作,以达到对电机进行有效保护之目的。文中同时对设计方案中涉及的两款较新的芯片HCNR200和AMS1117进行了简要的介绍和应用说明。
This paper introduces a design of the electric motor protection controller, which can be used to test the current and voltage information in 3-phase electricity, and can cut off the connectinon when there is something abnormal so that the electric motor can be protected. The two new chips HCNR 200 and AMS 1117 in the design are introduced and explained in application.
