New Synchronous Servo Motor Rexroth R911312867 MSK071D-0200-NN-M1-UG0-NNNN For Industrial Automation Systems

The REXROTH R911312867 MSK071D-0200-NN-M1-UG0-NNNN is a precision synchronous servo motor from the Rexroth MSK / IndraDyn S series. It is designed for industrial automation systems that require accurate speed control, repeatable positioning, compact mechanical integration, and stable torque output under demanding operating conditions. This motor is commonly used in packaging machinery, printing equipment, handling systems, machine tools, textile machinery, plastics processing machines, assembly lines, and other servo-driven production equipment.

The complete type code MSK071D-0200-NN-M1-UG0-NNNN identifies a motor with the MSK071D frame size, 0200 winding, natural convection cooling, multiturn encoder feedback, and shaft with keyway and shaft sealing ring without holding brake. The order number R911312867 should be used together with the full model code when checking compatibility or preparing a purchase request.

For product weight, the Rexroth MSK071D technical data lists the motor mass as 18.0 kg without holding brake and 19.6 kg with holding brake. Since this exact model ends with UG0, it does not include a holding brake, so the recommended net product weight is approximately 18.0 kg. Some reseller pages may show higher values such as 30 kg, but those values are usually stock-item or packed-weight references rather than the bare motor mass.

Main Product Information

Type Code Explanation

The full model code is important because Rexroth MSK motors can look similar externally while using different encoder systems, shaft options, brake configurations, and connector arrangements. For replacement projects, only matching “MSK071D-0200” is not enough. The full code MSK071D-0200-NN-M1-UG0-NNNN should be checked against the original nameplate.

The M1 multiturn encoder is one of the key differences between this model and many simpler singleturn versions. A multiturn encoder can provide absolute position information over multiple revolutions, which is useful in machines where the axis position must be retained after power-off, emergency stop, or machine restart. This can reduce homing time and improve operational reliability in automated production systems.

Technical Data

The MSK071D-0200-NN motor configuration provides a balanced combination of torque capacity, medium frame size, and controlled dynamic response. Based on Rexroth MSK071D-0200 technical data, this motor has 17.5 Nm continuous standstill torque at 60 K, 20.0 Nm continuous standstill torque at 100 K, 66.0 Nm maximum torque, and 3200 rpm maximum speed.

Product Weight and Packing Reference

The product weight is an important detail for equipment replacement, mechanical installation, warehouse handling, and international logistics. For this model, the most suitable net-weight reference is 18.0 kg, because the UG0 configuration does not include a holding brake.

For export packing, the final gross weight may be higher than the motor net weight. Wooden case packing, foam protection, shaft cover, moisture-proof wrapping, carton reinforcement, and pallet handling can increase the total shipping weight. Therefore, for product listings, it is better to state net motor weight: approximately 18.0 kg and confirm the gross packing weight before shipment.

Functional Characteristics

The REXROTH R911312867 MSK071D-0200-NN-M1-UG0-NNNN is suitable for servo systems that require accurate movement rather than simple constant-speed rotation. Its torque output allows it to drive medium-load axes, while its encoder feedback supports controlled positioning and precise speed regulation. The motor’s IP65 protection rating also makes it suitable for many industrial machine environments when installed with the correct cable and connector system.

The absence of a holding brake is not a defect. It simply means this motor is intended for machine axes where the mechanical load does not require a motor-integrated brake, or where external holding or safety braking is handled separately. For vertical axes, lifting units, or suspended-load systems, a brake-equipped version or an external safety brake should normally be considered.

Typical Applications

This servo motor is well suited for controlled motion in industrial machines. It can be used as a replacement motor in existing Rexroth-driven systems or as a component in machine-building projects where the electrical and mechanical design already supports the MSK071D series.

Installation and Compatibility Notes

When replacing a motor, the exact order number and full model code should be verified before purchase. A motor with a similar frame size may not be electrically or mechanically interchangeable if the encoder, brake, shaft, sealing, or connector configuration is different.

Procurement Guidance

For spare-part purchasing, the most reliable identification method is to use both the order number R911312867 and the complete model MSK071D-0200-NN-M1-UG0-NNNN. If the motor is being sourced as new, refurbished, or used, the supplier should confirm the nameplate, encoder condition, shaft condition, bearing condition, insulation test result, and whether the motor has been tested before shipment.

SEO-Oriented Product Summary

The REXROTH R911312867 MSK071D-0200-NN-M1-UG0-NNNN synchronous servo motor is a medium-frame IndraDyn S motor for precise industrial motion control. It features a 0200 winding, natural convection cooling, multiturn encoder, shaft with keyway, shaft sealing ring, no holding brake, IP65 protection, and an approximate net product weight of 18.0 kg. With 20.0 Nm continuous standstill torque at 100 K, 66.0 Nm maximum torque, and 3200 rpm maximum speed, it is suitable for packaging machines, printing systems, handling equipment, assembly automation, machine tools, textile machinery, and other servo-controlled industrial equipment. For accurate replacement and procurement, buyers should confirm both the Rexroth order number R911312867 and the full model code MSK071D-0200-NN-M1-UG0-NNNN before purchase.
