Motors Offer No Backlash

Description

Two new additions to the SDLM Series of high speed direct drive linear motors achieve resolutions of 5 and 1.25 µm. The integral, linear optical quadrature encoder directly connects to the shaft for the greatest possible accuracy. 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.

 

Each motor features a continuous force rating of 5.82 N and a peak force of 18.4 N. This motor has a large air gap of 1.5 mm, and allows the motor to be used for: vibration, noise cancelation, photonics, gimbals, antenna positioning, medical devices, and more.
