New Genuine Synchronous Servo Motor Rexroth R911316297 MSK070E-0300-NN-S2-UG1-RNNN For Industrial Equipment

The REXROTH R911316297 MSK070E-0300-NN-S2-UG1-RNNN is a high-performance synchronous servo motor from the Rexroth IndraDyn S MSK motor family. It is designed for demanding industrial motion applications where high torque density, accurate positioning, reliable feedback, and compact mechanical construction are required. The MSK070E frame size belongs to the medium-to-high output range of the MSK series and is commonly used in machines that require stable dynamic response under repeated acceleration and deceleration cycles.

For this configuration, the motor is based on the MSK070E-0300 winding variant. Public Rexroth MSK technical data lists the MSK070E-0300 version with a maximum speed of 5300 rpm, maximum torque of 65 Nm, standstill current around 15.4 A, and maximum current around 49.3 A. These values make the motor suitable for servo axes that need both continuous torque capability and strong short-time peak torque during positioning or load changes.

Basic Product Information

The MSK070E-0300-NN-S2-UG1-RNNN is intended for use with compatible Rexroth IndraDrive servo drive systems. In a complete automation system, the motor works as the actuator on the machine axis, while the drive controls speed, torque, and position based on command signals from the machine controller. This makes the motor appropriate for applications that require repeatable movement, accurate positioning, and stable torque delivery.

Weight and Mechanical Handling

The estimated weight of this motor is approximately 17.8 kg when configured with a holding brake. Similar MSK070E-0300 configurations with brake are listed by industrial servo suppliers at around 17.8 kg, while non-brake or different shaft and encoder variants may be listed closer to 16.2 kg. Because the requested model contains the UG1 configuration, the safer commercial description is approx. 17.8 kg, with final confirmation recommended from the actual nameplate or packing label before shipment.

For export packing, this product should not be treated as a light electronic component. It is a precision electromechanical servo motor with an encoder, bearing system, shaft end, connector section, and magnetic rotor. During packaging, the shaft and connector should be protected against impact, and the motor should be fixed inside foam or custom support material to avoid movement during transport. If the unit is shipped internationally, wooden case packing or reinforced carton packing is recommended depending on customer requirements and carrier rules.

Technical Characteristics

The MSK series is known for combining compact motor dimensions with strong output performance. Compared with older industrial servo motors, the IndraDyn S MSK range provides improved torque density, better feedback options, and a modular structure that allows many combinations of shaft, brake, encoder, and connector layouts. This is useful for machine builders because one motor family can cover different axis requirements while maintaining a consistent drive system architecture.

Model Code Explanation

This model code is important when sourcing replacement units. A similar-looking MSK070E motor may not be electrically or mechanically interchangeable if the encoder, brake, shaft, connector, or winding code is different. For example, an MSK070E-0300 motor with a different encoder code may require drive parameter changes or may not match the original machine configuration. Therefore, when replacing an installed motor, the full model MSK070E-0300-NN-S2-UG1-RNNN and order number R911316297 should be checked together.

Application Areas

The REXROTH R911316297 MSK070E-0300-NN-S2-UG1-RNNN is suitable for many industrial automation applications, including:

The motor’s high peak torque allows it to handle rapid acceleration demands, while the encoder feedback supports precise position monitoring. This is important in modern production equipment where movement errors can lead to material waste, downtime, or poor product quality.

Key Advantages

The holding brake is especially useful for vertical or inclined axes where the load must remain in position when the motor is not actively driving. However, the brake should be understood as a holding brake, not as a dynamic service brake for repeated stopping under full motion. For correct operation, the machine design should follow the drive system manual and safety requirements.

Buying and Replacement Notes

When purchasing the REXROTH R911316297 MSK070E-0300-NN-S2-UG1-RNNN, the most important point is to match the complete type code. Do not replace it only by the short series name MSK070E. The winding code, encoder code, brake option, shaft design, and connector orientation can all affect compatibility.

Before installation, the following items should be checked:

For used or refurbished stock, it is recommended to test insulation resistance, encoder feedback, brake release, bearing noise, shaft runout, and connector condition before delivery. For new surplus stock, packaging condition and storage history should also be checked, especially if the product has been stored for several years.

SEO Product Summary

The REXROTH R911316297 MSK070E-0300-NN-S2-UG1-RNNN synchronous servo motor is a precision motion control motor from the IndraDyn S MSK series. With an estimated weight of approximately 17.8 kg, a 070E frame size, 0300 winding, encoder feedback, natural convection cooling, and holding brake configuration, it is suitable for CNC machinery, packaging equipment, printing machines, handling systems, and other industrial automation applications. Its high peak torque, stable servo response, and compatibility with Rexroth IndraDrive systems make it a reliable choice for machine builders, maintenance teams, and automation spare parts replacement projects.
