Brushless direct drive motors

GOLDLINE DDR (direct drive rotary) high-torque, brushless motors provide precise operation in a compact package. Rare-earth, neodymium magnets are used to generate high continuous and peak torque ratings. The motors are mounted directly on a machine, eliminating the need for gearboxes, belts, and pulleys. Overall machine performance is improved because backlash is eliminated. The motors offer continuous torque ratings from 3.1 to 116.0 lb-ft; frame sizes are available from 6 to 10 in. Typical applications are wafer-handling robots, CMP tools (platen and head drives), and ion implantation drives. Kollmorgen, Radford, VA; ph 800/777-3786, fax 540/731-0847, www.kollmorgen.com.
