Considering that the belt conveyor will be damaged by rigid impact and load starting when starting and stopping,a soft start drive system is applied to a large number of belt conveyors,which mainly adopts permanent magnet direct drive roller,liquid viscous drive,frequency converter,CST controllable start drive system and flexible drive system FDS.The flexible starting mechanism of these five kinds of driving devices is introduced in detail.By comparing these five kinds of drive systems,their advantages and disadvantages and the economic benefits brought by soft start drive devices applied to belt conveyors are analyzed.
