- Company & Career
The EZM synchronous servo motor is suitable for driving a flanged threaded nut directly. Due to its generously dimensioned flange hollow shaft for introducing the threaded spindle, it can be used for threaded spindles of any desired length. Eliminate the ball screw coupling and pillow blocks for a more compact and cost-effective solution.

Ball screw drive manufacturers: HWIN, Steinmeyer, THK, Kammerer, NSK, NEFF
Attachment of threaded nuts from other manufacturers on request.
The ball screw drive is not included in the scope of delivery from STOBER.
Axial angular ball bearing acting on two sides for direct absorption of the threaded spindle forces.
Optionally the motor b-side can be equipped with a permanent magnet holding brake.
Absolute value encoder EnDat® 2.1 or EnDat® 2.2
- Optical or inductive measuring principle
- High system accuracy with up to 23 bits resolution
- Up to 4096 recordable resolutions in multiturn version
- Electronic nameplate ensures fast and easy commissioning
- Additional information transferred with the position value (EnDat® 2.2)
- Compatible with STOBER drive controllers and drive controllers of many third-party manufacturers
