Application of PLC Technology in the Variable-frequency
Regulating-speed Control System of Mine Hoist
Li Ziliang Gong Wenbin
Abstract:The mine hoist is one of the most important equipments. There are many problems in traditional electric controlled system in which speed is controlled by using rotor—ring resistance, such as, the fussy controlling way , breaking down easily and poor speed controlling etc. According to this kind of condition, we adopt PLC and Transducer to reform for original control system, so as to raise the safety, reliability, control precision and speed regulation performance of the whole electric controlled system.
