Product description
The EZ-0275 is a long-proven, direct-driven rotary table of medium size. Due to the torque motor (IDAM RMF 2- or 3-phase) dynamic applications up to 660 rpm can be realized. The rotary table is particularly suitable for applications that require very precise rotary motion and high repeatability. The measuring system (Numerik Jena RIK4) with 18,000 lines can optionally be supplied with interpolation factors of 5, 10, 50 or 100. Lower interpolation values allow for higher speeds, while higher interpolation values improve repeatability. The rotor is magnetically preloaded and clamps to the housing when the air supply is switched off, ensuring it remains fixed in position. There are no restrictions regarding the installation orientation. Due to the materials used and the fact that air bearings are generally operated without lubricants, the rotary table is suitable for use in clean rooms. The maximum permissible payload is 600 N.
Applications: High-precision positioning and measuring systems, inspection technology, testing systems, calibration systems, optical alignment, applications with high demands for synchronization and/or repeatability in positioning.
