Genuine New Synchronous Servo Motor Rexroth R911316296 MSK071E-0300-NN-M2-UG2-RNNN Design For Many Industrial Environments

The REXROTH R911316296 MSK071E-0300-NN-M2-UG2-RNNN is an IndraDyn S MSK synchronous servo motor designed for high-precision industrial motion control. It is built for equipment that requires strong torque density, repeatable positioning, stable speed regulation, and reliable closed-loop control. The order number R911316296 is associated with the full type code MSK071E-0300-NN-M2-UG2-RNNN, and public distributor data identifies it as a Rexroth IndraDyn S synchronous servo motor.

This model belongs to the MSK071E frame size, which is positioned in the medium-to-high torque range of the Rexroth MSK motor family. Compared with smaller MSK frame sizes, the MSK071E provides higher standstill torque and stronger overload capability while still keeping a compact servo motor structure. It is suitable for industrial machinery where the motor must support precise axis movement, controlled acceleration, and stable operation during repetitive production cycles.

The product weight is approximately 23.5 kg for the basic motor version without a holding brake. Rexroth MSK071E technical data lists the motor mass as 23.5 kg, with a bracketed value of 25.1 kg for a motor version with holding brake. The same technical data section lists IP65 protection, insulation class F, and an operating ambient temperature range of 0 to 40 °C. For shipping purposes, the packed weight should not be treated as 23.5 kg. Export packaging, carton, protective foam, shaft protection, pallet, or wooden case will increase the gross shipping weight.

The MSK071E-0300-NN-M2-UG2-RNNN is especially useful in systems where the motor must deliver both torque and precision. Servo motors in this class are commonly installed in automated machinery because they can respond accurately to position, speed, and torque commands from the drive controller. In a complete Rexroth servo system, the motor usually operates with an IndraDrive unit, power cable, feedback cable, encoder feedback, and machine-specific parameter settings. Correct matching between the motor and the drive is essential for safe commissioning and stable long-term operation.

The technical data for MSK071E-0300-NN shows a continuous standstill torque of 23.0 Nm at 60 K, 28.0 Nm at 100 K, and 34.5 Nm with surface cooling. The listed maximum torque is 84.0 Nm, and the maximum speed for the 0300 winding is 4200 min-1. These values make the motor suitable for axes that require controlled high-torque movement, but not necessarily the highest speed variant available in the MSK071E family.

The 0300 winding configuration is an important part of the selection. Within the same MSK071E frame, different winding codes can change the current requirement, voltage behavior, and maximum speed. The 0300 version gives a practical balance between torque capability and speed range. It is often more suitable than a very high-speed winding when the application requires firm torque response, steady control, and moderate-to-high dynamic movement.

The full type code must be checked carefully before replacement. A motor labeled only as MSK071E is not enough for accurate procurement. The winding code, encoder code, shaft design, connection arrangement, brake configuration, and additional variant letters can affect compatibility. A different encoder may not communicate correctly with the existing drive system. A different shaft or brake configuration may prevent direct mechanical installation. A different winding may require different drive current settings and different axis parameters.

The M2 encoder configuration supports precise feedback for closed-loop servo control. In practical operation, encoder feedback allows the drive system to detect rotor position and speed, then adjust the motor current according to the commanded motion profile. This is essential for equipment that requires accurate positioning, synchronized movement, repeatable indexing, and stable torque output. Applications such as packaging lines, CNC axes, robotic handling systems, printing machinery, and automated assembly stations depend heavily on this feedback quality.

In a CNC machine, the REXROTH R911316296 MSK071E-0300-NN-M2-UG2-RNNN can be used for a medium-load feed axis, rotary table, tool changer movement, or auxiliary positioning mechanism. In packaging equipment, it can control film transport, sealing movement, cutting cycles, or synchronized conveyor sections. In printing and converting systems, the motor can help maintain roller position, web tension, and registration accuracy. In automated assembly equipment, it can drive linear slides, indexing units, pressing stations, and material transfer axes.

The IP65 protection degree gives the motor a suitable housing design for many industrial environments, provided that installation is done correctly. IP65 protection helps protect the motor against dust and water jets, but it does not remove the need for proper cable sealing, connector tightening, and environmental review. High ambient temperature, excessive vibration, aggressive chemicals, oil mist, incorrect grounding, or poor ventilation can still reduce motor life or cause operating problems.

From a maintenance perspective, the motor should be handled as a precision electromechanical component. The shaft, encoder, bearings, and connector areas must be protected during storage and transport. A servo motor can be externally intact but internally damaged if it is dropped, exposed to strong impact, or stored in humid conditions without protection. Because this motor weighs about 23.5 kg, lifting and installation should be performed with suitable handling methods instead of forcing the shaft, connector, or housing.

For Google-indexed product content, the full product identity should be written clearly and naturally. Buyers often search by exact part number, full type code, or simplified product terms such as R911316296, MSK071E-0300-NN-M2-UG2-RNNN, Rexroth MSK071E servo motor, and IndraDyn S synchronous servo motor. A useful product page should include the order number, complete model, product weight, technical data, application fields, compatibility notes, and replacement precautions. This improves search relevance without excessive keyword stuffing.

In summary, the REXROTH R911316296 MSK071E-0300-NN-M2-UG2-RNNN is a medium-to-high torque IndraDyn S synchronous servo motor for precision industrial motion control. With an approximate net weight of 23.5 kg, 23.0 Nm continuous standstill torque at 60 K, 84.0 Nm maximum torque, 4200 min-1 maximum speed, IP65 protection, and a robust MSK071E frame, it is suitable for demanding servo axes in automated machinery. Before ordering or replacing this motor, the complete type code, order number, brake status, encoder configuration, shaft arrangement, cable compatibility, drive settings, and machine parameters should be verified carefully.
