Abstract

A conveying system may include a frame that supports a plurality of rollers which carry articles thereon. At least one of the rollers may be a motorized roller with first and second motors adapted to rotate an outer cylindrical shell of the motorized roller. A controller external to the motorized roller may send speed control commands to the motorized roller to control both the first and second motors in a manner that increases torque of the motorized roller. The motors may be controlled in four quadrant mode, or two quadrant mode, or a combination thereof. The motorized roller may be used in a right angle transfer mechanism, or in other components of a conveying system.
