Abstract
A roller conveyor including a plurality of driven rollers disposed in two parallel tracks. With each driven roller a separate drive motor is associated, which takes the form of a low voltage motor. The drive motors are supplied from at least one low voltage source. They are preferably hub motors, which are operated with direct current. By virtue of the low voltage technology, less expensive components may be used and the safety requirements may be reduced.
