High-performance modular system for direct-drive rotary tables
In directly driven rotary tables and swivel-type axes, the torque motor, the rotary table bearing, and the angular measuring system constitute a complex system with a large number of interactions regarding heat flow, cogging, speed and acceleration capability, rigidity, frictional torque, and positioning accuracy. It is therefore hugely beneficial if all three components come from a single source and are perfectly matched to each other in one modular system. Schaeffler Direct Drives, based in Suhl (Germany), offers three torque motor series for a wide range of applications, while Schaeffler offers three INA bearing series and an angular measuring system integrated into the bearing.
