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.
Threaded Nut Designs

Designed for ball screw nut drive of ball screws in accordance with DIN 69051. 

Maximum threaded spindle diameter:
EZM5: 25 mm
EZM7: 32 mm

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.
Bearing design

Axial angular ball bearing acting on two sides for direct absorption of the threaded spindle forces.
Bearing design
Motor Brake

Optionally the motor b-side can be equipped with a permanent magnet holding brake.
EZ Brake
Encoder

- 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
- Compatible with STOBER drive controllers and drive controllers of many third-party manufacturers
Power and Encoder Interface

- Rotating plug connectors with quick lock.
- Option: Supplied with mating connectors.
EZ Connection Method
Winding Protection

PTC thermistors are installed in STOBER synchronous servo motors as a configuration feature to implement thermal winding protection. This makes it possible for the motor to exceed the maximum permitted winding temperature with the appropriate devices turned off.
Paint Finish

- Housing and connector black RAL 9005
- Motor cover b-side magenta RAL 4010
Drive Controller Recommendation

- POSIDRIVE MDS 5000 with power range 0.75 to 45 kW
- POSIDYN SDS 5000 with power range 0.75 to 45 kW
- SD6 with power range 0.75 kW to 45 kW
- SI6 with power range 0.75 kW to 25.9 kW
