ABB Inc. has begun production of its ACS 800 electric motor drive units in New Berlin, Wis., the firm announced at NPE 2003.
Production at New Berlin will cut weeks off delivery lead times for the drives in North, Central and South America, compared with shipments from other plants operated by Zurich, Switzerland-based ABB Group.
ABB touted its alternating-current ACS 800 drives' motor control in injection molding machinery, extruders, melt pumps and pelletizers. ABB's Direct Torque Control technology in the ACS 800 drives requires no encoder or tachometer, cutting capital costs on new drive installations and retrofits.
The company said it has developed an Ethernet module that allows a motor drive to send e-mail alerting the operator to drive problems. Also new are permanent-magnet motors to replace gearboxes. ABB claims the new Direct Drive motor provides accuracy and reliability in plastics machinery that needs high torque at low speed.
ABB promoted the use of AC motors as brakes to replace traditional mechanical and air brake systems in film and sheet unwinders.
