The REXROTH R911312990 MSK101E-0200-NN-S2-AG0-RNNN is a high-output synchronous servo motor from the Rexroth MSK / IndraDyn S motor series. It is designed for demanding industrial motion-control systems that require high torque, accurate feedback, stable speed control, and reliable operation under continuous production conditions. This model is suitable for heavy-duty servo axes in packaging machinery, printing systems, machine tools, plastics machinery, handling equipment, forming lines, converting machinery, and automated production systems.
The complete type code MSK101E-0200-NN-S2-AG0-RNNN identifies a motor with an MSK101E frame size, 0200 winding, natural convection cooling, S2 encoder configuration, A-side power connection, and AG0 mechanical configuration without holding brake. The Rexroth order number R911312990 should be used together with the full type code when checking replacement compatibility or preparing a purchase request. LSA Control lists this exact reference as R911312990 MSK101E-0200-NN-S2-AG0-RNNN, described as an IndraDyn S synchronous servo motor.
For product weight, the most suitable reference for this non-brake MSK101E-0200 configuration is approximately 53.5 kg. This value is also found in MSK101E-0200 reference listings, while brake-equipped variants may require additional confirmation depending on the exact brake configuration. Since this model ends with AG0, it should be treated as a non-holding-brake version, so the recommended net motor weight for product listing is approximately 53.5 kg.

Type Code Interpretation
The full type code is important because Rexroth MSK motors may have similar external dimensions while using different encoder systems, brake configurations, shaft options, cooling arrangements, and connector orientations. For replacement work, the complete model code should be checked against the motor nameplate and drive documentation.
| Code Section | Meaning |
|---|---|
| MSK | Rexroth IndraDyn S synchronous servo motor series |
| 101E | Motor size 101 with E-length construction |
| 0200 | Winding variant |
| NN | Natural convection cooling |
| S2 | Encoder configuration, different from M1 or S1 variants |
| AG0 | A-side connection and non-brake mechanical configuration reference |
| RNNN | Additional motor configuration code |
The S2 encoder configuration is a critical identification point. A motor with the same MSK101E-0200 base code but a different encoder may not be a direct plug-in replacement. The encoder feedback must match the compatible drive controller, parameter set, cable arrangement, and machine configuration. When replacing an installed motor, the safest method is to match the full type code rather than only the frame size and winding code.

These values should be treated as MSK101E-0200 reference data. For final engineering selection, the official Rexroth project planning documentation, the motor nameplate, and the actual drive parameters should be checked before commissioning.
Product Weight and Shipping Information
The REXROTH R911312990 MSK101E-0200-NN-S2-AG0-RNNN should be listed with an approximate net product weight of 53.5 kg. This is the appropriate weight reference for the motor itself and should not be confused with the packed shipping weight. Some suppliers may list a higher logistics weight depending on wooden case packing, export packaging, or palletized shipment.
| Weight Item | Reference Value |
|---|---|
| Recommended Net Motor Weight | Approximately 53.5 kg |
| Holding Brake | No |
| Packing Weight | Must Be Confirmed Before Shipment |
| Export Packing Influence | Wooden case and pallet may increase gross weight |
| Listing Recommendation | State net weight and confirm gross weight separately |
For international B2B sales, it is better to separate net motor weight from gross shipping weight. The motor may require reinforced packaging because of its weight, shaft protection, encoder connector protection, and housing protection. A wooden case or export-grade carton should be used to reduce the risk of damage during long-distance transportation.
Design Characteristics
The R911312990 motor is designed for industrial servo systems where torque control, position feedback, and mechanical reliability are more important than simple rotational output. Its MSK101E frame provides high torque capacity in a servo motor format suitable for demanding production machines.
| Design Feature | Practical Benefit |
|---|---|
| MSK101E Large Frame | Suitable for heavy-duty servo axes |
| 0200 Winding | Provides high torque characteristics for demanding applications |
| Natural Convection Cooling | Simplifies installation where forced cooling is not required |
| S2 Encoder System | Supports precise feedback with compatible Rexroth drives |
| Non-Brake Configuration | Suitable for supported or horizontal axes without integrated holding requirement |
| IP65 Protection | Helps protect the motor in industrial machine environments |
| High Maximum Torque | Supports acceleration, deceleration, and short overload demand |
| 53.5 kg Net Weight | Important for machine mounting and logistics planning |
The non-brake configuration is suitable for axes where holding torque is not required when the drive is disabled, or where the machine uses an external holding system. For vertical axes, lifting mechanisms, suspended loads, or gravity-influenced axes, a brake-equipped version or external safety brake should be considered.
