Mounting Positions

- Any mounting position.
- You can find the explanation of the mounting positions and the respective quantities of lubricant in the document Quantity of lubricant for gear units ID 441871
Lubricants and Maintenance

- Mineral lubricant CLP ISO VG 220
- Option: Synthetic lubricant CLP HC ISO VG 220

Under normal operating conditions no lubricant change is required for gear unit size K1 to K4 (lubricated for life). 
We recommend a change of lubricant for gear unit size K5 to K10 after approx. 10,000 hours of operation.
Paint Finish

- Housing and connector black RAL 9005
- Motor cover b-side magenta RAL 4010
Synchronous Servo Motor EZ

- Extremely compact. 
- Highest power per unit volume. 
- Large torque. 
- High dynamic.
Synchronous Servo Motor EZ
External Fan

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)
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.
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
