Most of the traditional mining electric locomotives use DC series excited motors as traction motors. Series resistance speed regulation or chopper speed regulation is used for control. A few of the electric locomotives use three-phase asynchronous motors as traction motors. Frequency conversion speed regulation is used for control. The above systems have the advantages of simple structure, easy operation, low initial investment, etc., and are widely used in domestic mining electric locomotives. As mining enterprises put forward higher requirements for safety, efficiency, environmental protection and energy conservation, it is particularly urgent to replace traditional technologies with high-tech. Using permanent magnet synchronous motor as the control scheme of traction motor has the advantages of simple structure, high efficiency, good safety performance, reliable system, etc. It has broad application prospects in the mine traction industry.
At present, there are many kinds of trams for ore transportation in domestic mines, and large and medium-sized mines tend to use bottom dump and bottom side dump trams for transportation. Compared with other types of tramcars, these two types of tramcars can realize continuous loading and unloading
