New Original Synchronous Servo Motor Rexroth R911317865 MSK070E-0300-NN-S1-UP1-NNNN For Industrial Automation, Motion Control

The REXROTH R911317865 MSK070E-0300-NN-S1-UP1-NNNN is an IndraDyn S synchronous servo motor designed for high-precision industrial motion control. It belongs to the MSK070E motor size group, which is widely used in automation systems requiring strong torque density, accurate speed control, and reliable positioning performance.

The complete model number MSK070E-0300-NN-S1-UP1-NNNN identifies a specific Rexroth MSK servo motor configuration with 0300 winding, natural convection cooling, singleturn encoder feedback, keyed shaft with shaft sealing ring, and holding brake option according to the UP1 configuration. Public supplier data links the order number R911317865 directly with this full motor type code.

For this motor configuration, available technical references list a motor weight of approximately 16.2 kg, a maximum speed of 5300 rpm, and a maximum torque of 65 Nm. These values make it a mid-to-large range MSK servo motor suitable for demanding industrial equipment rather than light-duty positioning only.

Basic Product Information

Main Technical Data

The MSK070E-0300 motor platform is known for combining a compact motor body with a relatively high torque reserve. Public data for the R911317865 configuration indicates 65 Nm maximum torque, 5300 rpm maximum speed, and 16.2 kg weight, which are important values for selecting the correct drive, mounting structure, coupling, and machine axis design.

Detailed Product Description

The REXROTH R911317865 MSK070E-0300-NN-S1-UP1-NNNN is built for machines that need controlled rotary motion with high repeatability. In practical automation systems, the motor is normally paired with a compatible Rexroth IndraDrive servo drive. The drive controls motor current, speed, torque, and positioning commands, while the motor feedback system sends precise shaft position information back to the controller.

The MSK070E frame size gives this motor a useful balance between mechanical compactness and torque capacity. It is smaller and easier to integrate than large-frame servo motors, but it still provides enough torque output for many demanding axes. This makes it suitable for indexing stations, feed axes, packaging equipment, printing machinery, handling systems, automated assembly machinery, and other servo-driven equipment where stable motion is required.

The 0300 winding is one of the key elements in this type code. Winding selection affects speed range, current requirement, torque curve, and the final drive sizing. For this model, the maximum speed is commonly listed at 5300 rpm, which allows the motor to support applications where both positioning accuracy and relatively fast axis movement are needed. The maximum torque rating of 65 Nm gives the motor reserve capacity during acceleration, short overload periods, and load transitions.

The NN cooling code indicates natural convection cooling. This means the motor does not require a separate forced-air blower in its standard configuration. Natural convection helps reduce component count and simplifies machine layout. However, machine builders still need to leave enough space around the motor housing for heat dissipation. Continuous operation at high torque, enclosed installation, poor ventilation, or high ambient temperature may require derating or a different cooling approach.

The S1 encoder code indicates a singleturn encoder version. A singleturn encoder is suitable for many servo applications where the controller only needs absolute position information within one shaft revolution or where homing and reference routines are already managed by the machine control system. It provides accurate feedback for speed and position control, but it should not be confused with multiturn feedback, which retains position information across multiple revolutions. For replacement work, this distinction is important. An S1 motor should not be casually replaced with an M1 or M2 encoder version unless the drive configuration and machine control logic are verified.

The UP1 shaft and brake section is also important. The “U” generally refers to a keyed shaft with shaft sealing ring, while the “P1” configuration indicates the brake version in this motor code. A keyed shaft is useful when the driven element requires positive torque transmission through a key connection. The shaft sealing ring helps protect the motor from contamination at the shaft side, which is valuable in industrial environments where dust, oil mist, coolant, or light contamination may be present.

The holding brake is useful for keeping the axis in position when power is removed, especially for vertical or gravity-loaded axes. However, it should be treated as a holding brake, not as a dynamic service brake for repeated stopping under load. In machine design, emergency stopping, vertical load safety, and operator protection should be handled according to the full mechanical and electrical safety design, not only by relying on the motor brake.

Weight and Handling Information

The listed 16.2 kg should be treated as the approximate motor body weight. The actual shipping weight can be higher because of packaging, wooden box, foam protection, documents, cable accessories, or supplier-specific export packing. For logistics quotation, especially for DHL, FedEx, UPS, air freight, or international express service, both gross weight and volume weight should be checked before confirming freight cost.

During installation, the weight of the motor must be considered carefully. The motor should not be lifted by the connector, cable outlet, encoder housing, or shaft. The mounting flange should be aligned accurately with the machine bracket. Incorrect alignment can cause bearing stress, shaft vibration, coupling wear, abnormal heat, and reduced service life.

Application Fields

The R911317865 MSK070E-0300-NN-S1-UP1-NNNN is especially suitable for machines where compact installation space and strong dynamic performance are both required. Its 65 Nm peak torque reserve allows the motor to handle acceleration demands and short load spikes, while the 5300 rpm speed capability supports fast motion cycles.

Selection and Replacement Notes

For replacement, it is not enough to match only MSK070E-0300. The full code MSK070E-0300-NN-S1-UP1-NNNN should be checked. Similar motors may have different encoder types, shaft versions, brake configurations, or connection options. A wrong variant may physically fit but fail electrically, require drive parameter changes, or create machine safety risks.
