Mine hoist voltage motor energy saving technology - digital thyristor cascade control

    Of coal and metal mines mine hoist mostly followed the introduction of the former Soviet Union, series resistance winding rotor speed control technology, technology is

relatively mature, but there are many problems. Can
Silicon cascade speed control technology is also in the 1930s by the introduction of the former Soviet Union, but as previously used analog control method is not very accurate,

computer applications in industry as
The excessive constraints and other reasons, this technology has not been well developed and applied. In recent years, as computer technology has become more sophisticated, Telescopic conveyor

microcontroller, PLC, configuration
Technology, the rapid development of digital technology and applications, computer in the traditional silicon technology cascade control applications and more extensive control screw conveyor

accuracy and reliability get
Greatly improved, in some ways to be better than inverter and DC speed. |
