No backlash and high speed linear motors have integrated encoders

The integral, linear optical quadrature encoder is directly connect to the shaft for the greatest possible accuracy. Each motor features a continuous force rating of 20.1oz. (5.82N) and a peak force of 66.3oz (18.4N). This motor is designed with a larger air gap of 1.5mm (0.059”). The larger airgap allows the motor to be used for: vibration, noise cancelation, photonics, gimbals, antenna positioning, medical devices, semiconductor handling, SMT machines, assembly, wafer handling, optical focusing, dynamic vibration absorption, scanners and laser beam steering and filtering where excessive side play or tilt is required.

The non-commutating SDLM-025-095-01-05 (5µm resolution) and the SDLM-025-095-01-01 (1.25µm resolution) Direct Drive Linear Motors have quiet long life plain linear bearings, a non-rotating shaft, pre-drilled and tapped mounting holes, and threaded (internal) ends of the shaft for easy integration into new and existing applications.  

These low cost direct drive motors are coupled directly to the load providing high acceleration and speed with zero cogging and no backlash as with other drive systems such as ball screws, gear, and rack and pinion drives.

The SDLM-025-095-01-05 and SDLM-025-095-01-01 Direct Drive Linear Actuators are also available as a complete plug-and-play linear motion system with a matching motion controller.
