MSK101E-0450-NN-M1-AG2-NNNN

The Bosch Rexroth Indramat MSK101E-0450-NN-M1-AG2-NNNN synchronous servo motor from the MSK IndraDyn S Synchronous Motors series delivers industry-proven precision and high dynamic performance in a compact form factor. Its brushless design provides a continuous torque of 80.5 Nm at standstill with a continuous current draw of 67.6 A, while capable of producing a peak torque of 231.0 Nm under a maximum current of 262.4 A. The rotor and stator windings feature a high inductance value of 1,080 mH, supporting smooth current transitions and low torque ripple during rapid acceleration and deceleration profiles. Encased in a robust housing rated to IP65, this motor sustains reliable operation in environments with moderate exposure to dust and moisture. With a plain shaft interface and natural convection cooling, the MSK101E-0450-NN-M1-AG2-NNNN achieves an optimal balance between power density and thermal management.

Technical specifications for the MSK101E-0450-NN-M1-AG2-NNNN highlight its suitability for demanding motion control tasks. The motor length code is set to E and the size designation is 101, ensuring compatibility with standardized mounting footprints. The electrical connection on the A-Side power connector enables robust power delivery while the Hiperface encoder interface provides dual‐channel position and speed feedback. The multi-turn absolute optical encoder operates with 128 signal periods and delivers high resolution and reliability in closed‐loop control systems. The design constraint indicates a requirement for additional cooling options (FN), and the standard design type integrates an electrically released holding brake with a rated holding torque of 70 Nm for secure lock-in position holds.

Operationally, the motor’s natural convection cooling scheme maintains winding temperatures within safe limits under continuous operation, minimizing auxiliary cooling dependencies. The incremental winding code 0450 matches the specified current and torque ratings, enabling predictable thermal behavior across speed ranges up to the motor’s rated limit. The brushless configuration eliminates commutator maintenance, delivering long service intervals and reduced downtime. The plain shaft accommodates a variety of couplings and servo gearboxes, simplifying mechanical integration and alignment in multi-axle systems. Constraint requirements for cooling (FN) should be observed in high-duty-cycle deployments to preserve performance and longevity.

System integration of the MSK101E-0450-NN-M1-AG2-NNNN into Bosch Rexroth Indramat drive networks leverages native support within the IndraDrive controller family, facilitating real-time parameterization, auto-tuning, and motion profiling. The combination of high inductivity, precision encoder feedback, and holding brake functionality makes this servomotor ideal for robotics, synchronized multi-axis gantries, packaging machinery, and high-precision assembly lines. With its compact footprint and standardized mounting, it seamlessly replaces legacy units in retrofit scenarios or scales to new installations requiring consistent dynamic response and positional accuracy.
