High-speed, direct-drive linear motor with integrated encoder features 5-micron resolution

Moticont has added a linear motor to its SDLM Series of high speed direct drive linear motors which are also know as Electric Cylinders. The SDLM-051-095-01-05 is a powerful, compact linear actuator measuring just 2.00 in. (50.8 mm) in diameter and 3.75 in. (95.3 mm) long. It has a 1.0 in. (25.4 mm) stroke and features a resolution of 5 microns (0.000197 in.). The integral, linear optical quadrature encoder is directly connect to the shaft for the greatest possible bandwidth and accuracy and is protected by the housing. This fully enclosed linear motor features a continuous force rating of 7.6 lb (33.9 N) and a peak force of 24.1 lb (107.2 N) at 10 % duty cycle. Applications include: 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.

The non-commutating SDLM-051-095-01-05 with 5 micron resolution Direct Drive Linear Motor has a quiet long life plain linear bearing, 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 actuators or electric cylinders are coupled directly to the load providing high acceleration and high speed with zero cogging and the zero backlashes that occurs in other drive systems such as ball screws, gear, and rack and pinion drives.

They make a good, low-cost alternative to pneumatic and hydraulic actuators. The SDLM-025-095-01-05 Direct Drive Linear Actuator is also available with a complete plug-and-play matching motion controller.
