Conveyer belt assembly, method for its operation and usage

摘要

The conveyor (1) has a support structure (2) and a drive device (4) driving a conveyor belt (3). The drive device includes a drive shaft (5), a driving shaft-bearing arrangement (5a), a drive roller (6) and a separately excited drive motor (7) in the form of a frequency converter-fed alternating current synchronous motor having a stator (7a) and a rotor (7b). The drive shaft and the drive motor are gearless-connected with each other, where the rotor and the drive shaft are coaxially arranged, and the drive shaft is guided by the rotor that is mechanical firmly connected with the drive roller. An independent claim is also included for a method for manufacturing a belt conveyor.
