用PLC实现电动机的顺序控制

可编程控制器（PLC）是以微处理器为核心，将自动控制技术、计算机技术和通信技术融为一体而发展起来的崭新的工业自动控制装置。目前PLC已基本替代了传统的继电器控制而广泛应用于工业控制的各个领域，在实际应用中往往需要对电动机的顺序启动停止进行控制，本设计利用实验室的现有资源实现利用PLC控制电动机工作，对弱电驱动强电进行初...

PIC with the Order of the Realization of Motor Control

Programmable controller （PLC） is take the microprocessor as a core, the automatic control technology, the computer technology and the communication merges into one organic whole the brand-- new industry automatic control device which develops. But at present PLC basically has substituted the traditional black--white control widely to apply in industry control each domain, often needs to stop in the practical application to the electric motor smooth start carrying on the control, this design uses the PLC control motor work using the laboratory existing resources realization, carries on to the weak electric drive strong electricity searches initially.
