PI (Physik Instrumente) has released a new catalog of its magnetic direct drives and air bearing technology solutions, including actuators, linear stages, multi-axis gantry systems, and customized systems. Application-specific solutions include precision automation in optics and semiconductor manufacturing, assembly and test equipment.
The PIMag Magnetic Direct Drives, based on technology developed and manufactured in-house, deliver optimum performance via position and force regulation. Nanometer precision is achieved by closed-loop control with position feedback from absolute linear encoders or interferometers. Three-phase linear motors and voice coil drives provide fast acceleration, high scanning speeds, and extreme lifetime due to the zero-wear drive principle. Air bearings allow extremely uniform motion with constant velocity, extremely smooth positioning without rumble coupled in from mechanical bearings.
