胶带输送机由于运输距离长、运量大、采用单滚筒传动往往难以完成输送任务,所以考虑采用多滚筒传动。因而也必须考虑多电动机传动的功率平衡问题。即胶带在任何时候均能以稳定速度正常运转,在任何情况下都不会使其中任何一台电机由于高速运转而出现超载现象。一般在露天矿、海港等没有防爆问题的场所,可采用绕线型电机, Belt conveyor due to the long distance transport, transport capacity, the use of single-roller transmission is often difficult to complete the task of transportation, so consider the use of multi-roller drive. Therefore, it is also necessary to consider the power balance of the multi-motor drive. That is to say, the tape can operate normally at a steady speed at any time, and under no circumstances will any one of the motors overload due to high speed operation. Generally open-pit mines, seaports and other places without explosion problems, winding motor can be used,
