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
Power and Encoder Interface
- Rotating plug connectors with quick lock.
- Option: Supplied with mating connectors.
EZ Connection Method
Encoder
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
Resolver
- High temperature resistance
- High vibration strength and shock resistance
Power and Encoder Interface One Cable Solution (OCS)
- Rotating plug connector with quick lock (connection lines between the encoder and drive controller are routed along in the motor's power cable).
- Option: Supplied with mating connector.
EZ Connection Method (OCS)
Encoder One Cable Solution (OCS)
HIPERFACE DSL One Cable Solution (OCS)
- Significantly reduced wiring effort by eliminating the encoder cable
- Significantly reduced space requirements by eliminating the encoder plug connector
- High system accuracy with up to 20 bits resolution
- Up to 4096 recordable resolutions in multiturn version
- Electronic nameplate ensures fast and easy commissioning
- Additional information transferred with the position value
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
