Genuine New Synchronous Servo Motor Rexroth R911313196 MSK071E-0300-NN-M2-UG0-RNNN High Performance

The REXROTH R911313196 MSK071E-0300-NN-M2-UG0-RNNN is an industrial synchronous servo motor from the Rexroth IndraDyn S MSK motor platform. It is designed for precision motion control tasks where a machine axis must deliver accurate positioning, high repeatability, stable torque output, and reliable dynamic response. This model combines the MSK071E frame size, 0300 winding configuration, natural convection cooling, multiturn absolute feedback, a smooth shaft design, and a no-holding-brake configuration. The reference product weight for this non-brake version is approximately 23.5 kg, while brake-equipped variants in the same MSK071E family may have a higher weight.

The complete product identification is R911313196 MSK071E-0300-NN-M2-UG0-RNNN. The material number R911313196 is important for purchasing, spare part matching, inventory control, and after-sales maintenance. The model code MSK071E-0300-NN-M2-UG0-RNNN describes the motor’s technical configuration. For industrial replacement work, both identifiers should be checked together because motors with similar MSK071E-0300 prefixes may have different encoder systems, brake options, shaft configurations, or mechanical accuracy versions.

Basic Product Data

The REXROTH R911313196 servo motor is suitable for machine builders and maintenance users who need a compact but powerful motor for controlled axis movement. It can be used in packaging machines, feed axes, printing equipment, handling systems, automation cells, textile machinery, forming equipment, indexing units, and other production machines that depend on accurate servo control. Unlike a standard induction motor, this unit is intended to operate in a closed-loop drive system. The servo drive continuously reads the motor feedback signal and adjusts the output current to control torque, speed, and position.

The MSK071E frame gives this motor a useful balance between power density and installation size. It is not a small light-duty motor, but it is still compact enough for many machine frames where space is limited. With an approximate weight of 23.5 kg, the motor should be handled as a medium-weight industrial component. During installation or replacement, the motor should be supported correctly so that the shaft, connector, encoder housing, and mounting flange are not damaged. For shipping, the packed gross weight may be higher because of protective foam, carton, wooden case, or pallet packaging.

The 0300 winding configuration is commonly used where the application needs strong torque delivery with stable motion performance. The published performance references for this model include 28.0 Nm continuous torque at standstill and 84.0 Nm maximum torque. These values make the motor suitable for axes that require controlled acceleration, reliable load movement, and short-cycle operation. In practical use, the actual available torque depends on the servo drive, operating voltage, current limit, cooling condition, duty cycle, and mechanical load.

One of the most important features of this model is the M2 encoder configuration. The motor uses an optical multiturn absolute feedback system with EnDat 2.1 type feedback and a high-resolution signal structure. This allows the machine controller to identify the motor position across multiple shaft revolutions. In many automated systems, this helps reduce homing time, improve restart behavior, and maintain more reliable axis referencing after shutdown. This is especially useful for material handling axes, rotary tables, positioning slides, feed rollers, and synchronized machine sections.

The NN cooling code means the motor uses natural convection cooling. This design simplifies the machine layout because it does not require an external fan or liquid cooling circuit. Natural convection can reduce auxiliary maintenance points and make the motor easier to integrate into compact equipment. However, the thermal performance of the motor still depends on the installation environment. Ambient temperature, mounting surface, cabinet ventilation, operating cycle, and machine load all affect the final temperature behavior. For continuous high-load use, the complete axis should be checked against the motor and drive sizing data.

The UG0 part of the model code is also important. It indicates a smooth shaft and no holding brake configuration. A smooth shaft is typically used with a coupling, belt pulley, gearbox input, or other mechanical transmission selected by the machine builder. Because this version does not include a holding brake, it is normally more suitable for horizontal axes or systems where load holding is managed by the mechanical design or external equipment. If the axis is vertical or must hold a suspended load when power is removed, a brake-equipped variant or external holding mechanism should be considered.

The RNNN ending indicates a specific design variant and accuracy-related configuration. In replacement work, this ending should not be ignored. Motors that appear similar may still differ in mechanical runout class, design version, or factory configuration. When replacing a failed motor, users should compare the nameplate carefully and confirm the installed drive parameters before commissioning. An incorrect encoder type, brake option, shaft style, or connector orientation can cause installation problems, drive alarms, or unsafe machine behavior.

This motor is typically integrated with Rexroth IndraDrive servo systems. Correct pairing between the motor and servo drive is essential. The drive must support the motor data, encoder interface, current requirements, and application dynamics. After installation, the drive parameter set, encoder feedback recognition, motor direction, brake logic if applicable, and machine reference position should be verified before the equipment returns to production.

For procurement and technical documentation, the recommended listing name is REXROTH R911313196 MSK071E-0300-NN-M2-UG0-RNNN Synchronous Servo Motor. This name includes both the material number and the complete model, which improves search accuracy and reduces the risk of ordering the wrong version. For online product pages, the material number, full model code, servo motor type, MSK071E series, 0300 winding, multiturn encoder, natural convection cooling, no-brake configuration, and 23.5 kg reference weight should all be included to support technical search visibility.

The REXROTH R911313196 MSK071E-0300-NN-M2-UG0-RNNN is a practical choice for users who require a high-precision servo motor for industrial automation systems. Its combination of compact MSK071E construction, strong torque capability, multiturn absolute feedback, natural convection cooling, and no-brake smooth shaft configuration makes it suitable for many controlled motion applications. Before purchase or replacement, the full type code should be checked against the existing motor, drive system, cable set, mechanical coupling, and machine axis requirement.
