Linear Motor Stages - High Speed & High Precision - Linear Motor Actuators

Linear motors based on electrodynamic (magnetic) direct drives provide high speed and acceleration over large travel ranges. Due to the lack of friction, very good resolution and repeatability is feasible and the lifetime of the motor is not limited by wear and tear. Linear motor stages are often used in industrial automation applications where throughput and speed are crucial. PI linear motor stages are available with ironless (no cogging) and ironcore (higher force) 3-phase motors and voice coil drives (shorter travel ranges). Optical linear incremental encoders or optical linear absolute encoders are integrated to provide position feedback. Mechanical bearings and air bearings for ultra-high precision applications are available.

When the highest geometrical performance is required, linear motor stages with air bearings are recommended.

Voice-Coil Linear Motor Actuators with Mechanical Bearings and Flexure Guides

This OEM actuator was designed for automation applications. Its friction-free, low inertia voice coil linear motor provides high dynamics with velocities to 250mm/sec. The position is controlled precisely via an integrated linear encoder. An optional high-resolution force sensor further helps with integration into sensitive automation applications. Force and position are controlled by PI's C-413 PIMag™ Motion Controller.
