A continuous conveyor such as, for example, a conveyor belt for transporting heavy bulk materials or unit loads comprises an endless tractive transport mechanism that revolves between a driving roller and a return roller. The driving roller is driven by a permanently excited multi-pole synchronous motor that delivers a very high torque at a comparatively slow nominal speed. The synchronous motor can drive the driving roller directly or alternatively via a single-stage step-down gear with low reduction factor. The drive is characterized by a mass moment of inertia that is up to 10-times lower than in conventional drive systems. In this way, the risk of damaging or even tearing the belt during disruptions is substantially reduced such that the operational reliability significantly increases. |
