The new frameless servo motors in Wittenstein cyber motor’s cyber kit line are designed for installation directly in OEM machines and specially adapted for applications with high performance requirements. Not only are they wear-free and backlash-free; they also convince with high torque density, energy efficiency and robustness.
The modular concept of the cyber kit line large offers a high degree of design flexibility plus adaptability to specific tasks and conditions. For example, the frameless servo motors in the 560 V voltage class are available in four sizes from 290 to 530 mm as well as in various lengths from 50 to 200 mm and with four hollow shaft diameters from 220 to 420 mm.
The latter allow cables of, say, gripping elements, sensors and light guides or pneumatic air and vacuum tubing to be laid in a space-saving way inside the machine. Integrated PT1000 and PTC temperature sensors permit thermal condition monitoring.
Due to the high copper fill factor of the stator, the maximum torque of these torque-optimized motors ranges from 1000 Nm to more than 9000 Nm. Speeds of up to 250 rpm are specified. Whereas the cyber kit line large works with all standard servo drive makes, cyber kit line small motors are additionally compatible with the compact servo drives in the cyber simco drive 2 product family. They enable highly dynamic drive applications to be realized with higher output ratings.
