Voice coil direct drive with direct position measuring
Fast scanning and positioning
Crossed roller bearings for the highest precision
Reference-class linear stage Linear stages with magnetic direct drives largely dispense with mechanical components in the drivetrain and the drive force acts directly on the motion platform. Together with precision bearings, a high travel accuracy and longer lifetime is achieved. The linear stages are particularly suitable for scanning applications.
Crossed roller guide With crossed roller guides, the point contact of the balls in ball guides is replaced by line contact of the hardened rollers. Consequently, they are considerably stiffer and need less preload, which reduces friction and allows smoother running. Crossed roller guides are also distinguished by high guiding accuracy and load capacity. Force-guided rolling element cages prevent cage creep.
Fields of application Industry and research. Metrology, photonics, and precision scanning in semiconductor or flat panel display manufacturing
PIMag® voice coil Voice coil drives consist of 2 essential components: A permanent magnet and a coil that is located in the air gap of the magnetic field. When current flows through the coil, it moves in the magnetic field of the permanent magnet. The direction of motion depends on the polarity. Thanks to their low weight and friction-free drive principle, voice coil drives are particularly suitable for applications, which require high dynamics and high velocities at limited travel ranges. High scan frequencies and precision positioning are also possible with these drives, because they are free of the effects of hysteresis.
Highly accurate position measuring with incremental linear encoder Noncontact optical encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement.
