New Synchronous Servo Motor Rexroth R911317820 MSK100B-0200-NN-M2-AP0-RNNN For Industrial Systems

The REXROTH R911317820 MSK100B-0200-NN-M2-AP0-RNNN is a high-performance synchronous servo motor from the IndraDyn S MSK100B series, designed for industrial automation systems that require stable torque output, accurate positioning, and reliable long-term operation. This motor belongs to the larger MSK frame sizes and is commonly used in machinery where dynamic movement, controlled acceleration, and repeatable positioning are critical.

The full type code MSK100B-0200-NN-M2-AP0-RNNN identifies a compact but powerful servo motor with the MSK100 frame size, B-length design, 0200 winding, natural convection cooling, multiturn encoder feedback, keyed shaft configuration, and no holding brake. The order number R911317820 is associated with this specific Rexroth motor configuration in supplier listings.

For the MSK100B-0200 motor platform, published technical references show a maximum torque of 102 Nm and a maximum speed of approximately 4100 rpm. The motor mass for the MSK100B-0200 platform is generally listed around 35 kg, while shipment or package weight may be higher depending on packing material, accessories, and supplier handling method.

Basic Product Information

Technical Characteristics

The MSK100B-0200 specification family is suitable for applications that need strong peak torque and controlled dynamic response. Technical references for the MSK100B-0200 winding list 28 Nm continuous torque at standstill under 60 K conditions, 33 Nm under 100 K conditions, and 102 Nm maximum torque, which makes this motor suitable for demanding machine axes rather than only light-duty positioning systems.

Product Description

The REXROTH R911317820 MSK100B-0200-NN-M2-AP0-RNNN is engineered for servo-driven machinery where power density, accuracy, and mechanical stability must work together. As part of the Rexroth IndraDyn S MSK motor family, it provides high torque output in a compact synchronous motor structure. The MSK100B frame is larger than many standard low-power servo motors, which means it is better suited for heavier motion axes, rotary tables, packaging machines, handling systems, forming equipment, printing machinery, and other automated systems requiring reliable torque delivery.

One important feature of this model is its 0200 winding, which provides a balance between torque output and speed capability. The maximum speed of the MSK100B-0200 platform is typically around 4100 rpm, allowing it to support both medium-speed and high-torque motion tasks. This is useful in applications where the motor must accelerate a load quickly but still maintain controlled movement during positioning or indexing cycles.

The NN section in the type code indicates natural convection cooling. This means the motor is designed to dissipate heat through its housing without requiring an external blower in the standard configuration. Natural convection cooling simplifies machine design because it reduces auxiliary components, wiring, and maintenance points. However, the final operating performance still depends on ambient temperature, installation space, duty cycle, drive settings, and mechanical load conditions.

The M2 encoder feedback configuration supports precise position and speed feedback for servo control. In practical automation systems, accurate feedback is essential because the drive controller must constantly compare commanded motion with actual shaft position. This allows the motor to deliver controlled acceleration, stable speed regulation, and repeatable stopping accuracy. For CNC machines, robotics, transfer systems, and indexing equipment, encoder performance directly affects motion quality and final product consistency.

The AP0 part of the model code indicates a shaft and brake configuration suitable for systems that do not require an integrated holding brake. In many horizontal or mechanically self-locking axes, a holding brake may not be necessary. Removing the brake can reduce complexity and avoid brake wear issues. However, for vertical axes or suspended loads, the machine designer must evaluate whether an external brake, counterbalance, or safety holding mechanism is required.

The approximate 35 kg motor weight is important for both installation and machine design. This is not a small servo motor. Mounting plates, motor brackets, coupling systems, and lifting methods should be selected accordingly. During installation, technicians should avoid supporting the motor only by the shaft, connector, or encoder housing. Correct alignment between the motor shaft and driven component is also important because misalignment can increase bearing load, vibration, coupling wear, and operating noise.

Application Areas

The MSK100B-0200-NN-M2-AP0-RNNN is particularly suitable where the system needs a strong torque reserve. Its 102 Nm maximum torque allows short acceleration peaks and load changes without immediately oversizing the motor frame. This can help machine builders maintain a compact mechanical design while still achieving robust dynamic performance.

Weight and Installation Notes

The listed 35 kg should be treated as the motor body weight reference. For logistics, the real shipping weight may be higher because of carton, wooden box, foam protection, documentation, and possible accessories. For international trade or air freight quotation, it is safer to request both gross weight and packing dimensions before confirming freight cost.

Procurement and Replacement Considerations

When purchasing or replacing this motor, the full model number should be checked carefully. A small difference in the Rexroth MSK code can change the encoder type, shaft design, connector direction, brake configuration, or cooling method. For example, another MSK100B-0200 motor may have a different encoder or shaft option and may not be a direct replacement.

Summary

The REXROTH R911317820 MSK100B-0200-NN-M2-AP0-RNNN is a robust IndraDyn S synchronous servo motor designed for demanding industrial motion control applications. With a MSK100B frame, 0200 winding, natural convection cooling, multiturn encoder feedback, keyed shaft configuration, and no holding brake, it is suitable for machine axes requiring strong torque, accurate positioning, and stable dynamic response.

Its approximate 35 kg motor weight confirms that it is a heavy-duty servo motor rather than a compact low-power unit. Proper mounting, shaft alignment, lifting method, and drive matching are important for reliable operation. For replacement or procurement, the complete order number and full type code should always be used to avoid configuration mismatch.

For industrial automation users, machine rebuilders, and spare parts suppliers, this model is a practical choice for applications involving CNC machinery, packaging equipment, printing machines, handling systems, and factory automation lines where Rexroth MSK servo performance is required.
