摘要
介绍了磁栅位移传感器的结构及其工作原理,详述了磁栅传感器在塑壳式断路器智能测控系统中的应用,由步进电机、磁栅位移传感器、西门子PLC组成的控制系统实现了对步进电机的闭环控制,提高了步进电机的控制精度,降低了控制系统的成本,在现场中取得了良好的控制效果。
The structure and working principle of the magnetic grid displacement sensor are present first, the application of the magnetic grid displacement sensor in the intelligent control system of the mould case circuit breaker is also present in details, the closed loop control is realized by control system which composes the stepping motor, magnetic grid displacement sensor and PLC, improving the controlled accuracy of the stepping motor, reducing the cost of the control system, well controlled results are also achieved.
