Bosch Rexroth Corp. of Hoffman Estates, Ill., has introduced a number of machine drives and motion controllers, for use with plastics machinery.
The IndraDyn L series uses permanent magnets to create linear drive motors.
The Electric Drives and Controls business unit is marketing VisualMotion, an open motion/machine controller that ensures a shorter changeover time and high accuracy. Precision servo drive replaces mechanical elements such as gears, shafts and cams to simplify machine design.
Electric Drives and Controls also introduced the Ecodrive Cs, an extremely compact servo drive in the low-power range.
A new torque motor, the Rexroth IndraDyn T, can run from 25-700 revolutions per minute with a maximum speed up to 1,200 rpm. These direct-drive motors eliminate wear-prone mechanical elements such as gears.
The IndraDyn A induction motor, with an air-cooled and water-cooled motor, is easy to fix. The company said a fan can be replaced in minutes, even with the motor running.
The compact IndraDyn M, which incorporates Rexroth servo-drive and frequency converter technology on a single platform, can be used in injection molding machines, blow molders, thermoforming machines, extruders and material-handling systems.
New screw-in cartridge valves from the Industrial Hydraulics business unit are small and easy to use.
Bosch Rexroth also announced the DPQ-2X digital injection cylinder controller for hydraulic injection cylinders, and the DPC digital clamp axis control for hydraulic clamping systems. Both have analog or digital feedback.
