The new RollerDrive and DriveControl High Torque Brushless component (HTBL) is built to serve as an economical and safe alternative to traditional belt, line shaft, chain, and sprocket drive systems. The 24 Vdc-powered roller is able to move and control heavy loads and can reduce noise emissions to 45 to 50 dBA when the unit is mounted in structural frames. With speeds up to 256 feet per minute and gear ratios of 12:1 to 64:1, the RollerDrive HTBL consistently moves up to 500 lbs and, in testing, has moved 1,000 lbs. The roller is ideally suited for material handling applications where accumulation or general transport is required, such as postal and parcel distribution, warehouse conveying and order picking, distribution centers, packaging, and the pharmaceutical industry. Measuring 1.9 in. in diameter, RollerDrive tubes are available in lengths of 10 to 50 in. and with 0.065 in. thick galvanized carbon steel, stainless steel, or aluminum construction. The fully programmable, intelligent DriveControl HTBL allows engineers to control the RollerDrive based on their application needs. The DriveControl features soft, configurable limits for speed, torque, acceleration, deceleration, and current limiting. The unit interfaces with either NPN or PNP photo eyes and can be externally controlled via any external analog signal or PLC, such as an outboard potentiometer. Furthermore, the four-quadrant controller provides acceleration and deceleration control as well as the ability to stop, hold, and control motion on inclines, declines, and spirals.
