The Bosch Rexroth Indramat MSK100A-0300-NN-M2-BP0-RNNN is a high-performance synchronous servomotor in the MSK IndraDyn S Synchronous Motors series, engineered for precision position control in demanding industrial applications. This model delivers a maximum torque of 54.0 Nm and supports a maximum current of 45.9 A, ensuring robust dynamic performance. The motor achieves a top speed of 5200 r/min and incorporates a shaft with keyway design, optimizing torque transmission efficiency. Featuring an IP65 degree of protection, the MSK100A unit is dust-tight and water-resistant for reliable operation in challenging environments.
The servomotor’s technical pedigree is defined by its EnDat2.1 encoder interface with 2048 signal periods resolution and multiturn absolute encoder technology, enabling exact position feedback over multiple revolutions. Winding characteristics include a winding code 0300, winding inductivity of 11,200 mH, and a continuous current at standstill (100 K) of 11.6 A delivering continuous torque at standstill (100 K) of 17.0 Nm. The rotor’s moment of inertia of 0.01100 kg·m² pairs with natural convection cooling to maintain thermal stability under load. A B-side power connector ensures standardized electrical coupling, and the motor’s design with increased concentricity supports smooth, low-vibration operation.
Operational features emphasize energy efficiency and performance: the MSK100A series yields a torque constant of 1.70 Nm/A, enabling precise torque control with minimal current draw. Under surface cooling, the unit sustains a constant output torque of 22.5 Nm at a steady current of 15.3 A. The overall unit weight of 23 kg balances structural rigidity with manageable system mass. A leakage capacitance of 4.6 nF (discharge capacity) minimizes EMI effects, while the motor’s sound pressure level of 75 dB supports quieter machine operation. The sealed housing is compliant with an insulation level of 155, safeguarding windings against transient overvoltages.
System integration is streamlined through the IndraDyn S Synchronous Servomotor architecture, which interfaces seamlessly with Bosch Rexroth drives and controllers. The natural convection cooling approach eliminates external fans, reducing maintenance and simplifying installation. Without a holding brake, this unit is optimized for applications where external braking systems are already in place. With its compact motor size 100 and motor length A, the MSK100A-0300-NN-M2-BP0-RNNN is targeted at packaging machines, machine tools, and food processing equipment that demand precise position control, high torque density, and robust protection against environmental ingress.
