Synchronous Servo Motors for Screw Drives

The super compact synchronous servo motors for screw drives have been designed for universal mounting on the threaded spindles of a variety of manufacturers. The EZS model has a clamping assembly for tightening the threaded spindle. The EZM synchronous servo motor is suitable for driving the threaded nut directly. A threaded spindle of any desired length can be inserted through the generously dimensioned flange hollow shaft.

BENEFITS
The World’s Toughest Gearboxes

STOBER’s ballscrew motors eliminate extra components, offer better performance, and run cooler than other motors.

Shaft tensioning is simplified. These motors can be mounted on several manufacturers’ spindles.


KSS: For the toughest environments

The EZM series can handle threaded spindles of any length.

It saves space by eliminating ball screw coupling and pillow blocks.
Shaft tensioning is made simple. The flange meets DIN 69051-5 requirements.

K/KL: For right angle applications

The EZS series drives the rotating threaded spindle.

Pre-tensioning the shaft is simple as forces won’t be transmitted through the bearings.

“We are about to mount the motors on this prototype that we were asked to design, build and demonstrate in 4 weeks. The STOBER K402 gearboxes are in place and ready to go. Thank you to STOBER for quickly responding to my multiple quote requests for different options and for the quick delivery of these units. On this tight timeframe and in the current world supply chain situation, I think STOBER is the only manufacturer that I could count on to get us the high-quality units that we needed for this project.”
