Precise New Synchronous Servo Motor Rexroth R911316198 MSK070D-0300-NN-M2-UG0-RNNN Strong Choice For Industrial Users

The REXROTH R911316198 MSK070D-0300-NN-M2-UG0-RNNN is an IndraDyn S MSK synchronous servo motor designed for high-performance motion control systems, precision automation equipment, and industrial servo drive applications. This model belongs to the MSK070D frame size and uses the 0300 winding configuration, making it suitable for demanding axes that require stable torque output, accurate positioning, and reliable dynamic response. Public product listings identify R911316198 as the material/order number for MSK070D-0300-NN-M2-UG0-RNNN, an IndraDyn S synchronous servo motor.

The MSK070D-0300-NN-M2-UG0-RNNN is built for applications where both mechanical strength and control accuracy are important. In automated machinery, the servo motor is not only responsible for rotation; it must also maintain repeatable positioning, rapid acceleration, controlled deceleration, and stable torque under variable load conditions. The MSK070D frame provides a strong balance between compact installation size and high torque capability, which makes it suitable for medium-to-heavy servo axes in industrial automation systems.

According to Rexroth MSK070D technical data, the MSK070D-0300-NN configuration has a continuous standstill torque of 17.5 Nm at 60 K, 20.0 Nm at 100 K, and 26.3 Nm under surface cooling conditions. The same data table lists a maximum torque of 52.5 Nm for the MSK070D family and shows the MSK070D-0300-NN column with a continuous standstill current of 11.0 A at 60 K, 12.6 A at 100 K, and 16.5 A with surface cooling.

The product weight is approximately 13.9 kg for the motor without a holding brake. Rexroth documentation defines mass as the motor mass without the holding brake option, and the MSK070D table lists 13.9 kg, with the bracketed value applying to versions with a holding brake. Because the model code MSK070D-0300-NN-M2-UG0-RNNN is a no-brake configuration, 13.9 kg is the correct reference net motor weight. For shipping, the actual packed weight should be higher because of carton, protective foam, wooden case, cable protection, and export packaging.

The MSK070D-0300-NN-M2-UG0-RNNN is suitable for machine builders and maintenance teams that require a servo motor with dependable torque density and strong compatibility with Rexroth drive platforms. In a servo system, the motor is typically matched with a suitable IndraDrive controller, feedback cable, power cable, and application-specific parameter set. Correct drive matching is important because the motor’s torque curve, maximum speed, current demand, encoder feedback type, and mechanical load must all be considered before installation.

From a mechanical perspective, the MSK070D frame size is often used where smaller servo motors do not provide enough torque reserve. The 52.5 Nm maximum torque rating gives the axis enough overload capability for acceleration peaks, load changes, and dynamic positioning cycles. This is valuable in packaging machinery, feeding systems, indexing tables, textile machinery, printing units, electronic assembly equipment, and CNC auxiliary axes. The IP65 protection class also makes the motor appropriate for industrial environments where dust and limited water exposure may be present, provided that the motor is installed correctly with suitable connectors and sealing measures.

The M2 encoder configuration supports precise feedback for closed-loop servo control. In practical machine operation, encoder feedback allows the drive system to monitor rotor position and speed in real time. This helps the equipment maintain high repeatability, smooth running behavior, and controlled torque output. For applications such as synchronized conveyor systems, rotary tables, tension control, robotic handling, and high-speed positioning units, this feedback function is essential for stable operation.

Another advantage of this model is its ability to work in applications where compact torque output is required. The MSK series is widely used because it combines servo performance with a modular type-code structure. Users can identify important configuration details directly from the model number, including frame size, winding, cooling method, encoder system, shaft and connection design, brake option, and additional version codes. This reduces the risk of ordering the wrong motor and makes replacement work more efficient when maintaining existing Rexroth servo systems.

For procurement and replacement, the most important point is to match the complete type code, not only the short frame designation. MSK070D-0300-NN-M2-UG0-RNNN should not be replaced casually with another MSK070D motor unless the winding, encoder, shaft, connection, brake option, and system compatibility are confirmed. Even when two motors share the same frame size, differences in encoder type or shaft configuration may prevent direct replacement. The order number R911316198 is therefore highly useful when checking availability, quotation accuracy, and compatibility.

The REXROTH R911316198 MSK070D-0300-NN-M2-UG0-RNNN is a strong choice for industrial users who need a robust servo motor for accurate and repeatable motion control. Its 17.5 Nm continuous standstill torque at 60 K, 52.5 Nm maximum torque capability, 4900 min-1 maximum speed for the 0300 winding, IP65 protection, and approximately 13.9 kg net motor weight make it suitable for a wide range of medium-load automation axes. For best results, the motor should be installed by qualified personnel, matched with the correct Rexroth drive, and checked against the original machine parameters before commissioning.
