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

Direct-drive, linear stages provide high performance, speed and acceleration over large travel ranges. Direct-drive linear motors are usually based on the electrodynamic (magnetic) principle, but piezoelectric direct-drive motors are another option. These motors are usually based on the electrodynamic (magnetic) principle, but piezoelectric direct-drive motors are another option.  Due to the lack of friction, very good resolution and repeatability is feasible and the lifetime of the direct drive motors 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 direct-drive 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.  PI also offers Direct-drive rotary stages.

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