The Bosch Rexroth Indramat MSK061B-0300-NN-M1-UP1-NNNN is a high-performance synchronous servomotor in the MSK IndraDyn S Synchronous Motors series. This MSK061B-0300-NN-M1-UP1-NNNN model delivers precise motion control with a continuous torque at standstill of 3.9 Nm and supports dynamic loads up to a maximum torque of 14.0 Nm. Designed by manufacturer Bosch Rexroth Indramat, it combines compact dimensions with robust thermal management to sustain extended duty cycles. Its integrated multiturn absolute encoder and standardized interface make it ideal for demanding automation tasks requiring exact positioning and repeatability.
Detailed technical specifications are engineered for seamless integration and reliability. The motor features continuous current at standstill 100 K of 2.1 A and a maximum current of 8.6 A, ensuring consistent performance across variable loads. Thermal design is supported by natural convection cooling and a winding inductivity of 44,000 mH for stable current waveforms. The encoder subsystem comprises an optical encoder technology with Hiperface encoder interface, 128 signal periods resolution, multiturn absolute encoder turn type, and a rotatable 240° encoder connector. The physical form factor is defined by motor size 061 and motor length B, while the shaft with keyway provides secure coupling to driven elements.
Operational features emphasize efficiency and longevity under industrial conditions. The rotor’s moment of inertia of 0.00075 g·m² enables rapid acceleration and deceleration, while a thermal time constant of 18.0 minutes protects against overheating during high-duty cycles. Maximum permissible speed reaches 3100 min⁻¹, with sound pressure levels maintained below 75 dB(A) for quieter operation. The motor includes a with holding brake, electrically-released configuration delivering holding brake torque of 10 Nm for safe standstill on inclined axes. Its standard design ensures compatibility with common mounting arrangements and minimizes custom adaptation.
System integration is streamlined through compatibility with IndraDrive controllers and Rexroth HMI platforms, enabling advanced tuning and predictive diagnostics. The product type IndraDyn S Synchronous Servomotor works seamlessly in robotics, packaging, and CNC machine tool applications where precise torque control and high reliability are critical. IP65 protection supports operation in dusty or wet environments, while ambient operating temperatures from 0 °C to 40 °C and maximum installation up to 1000 m altitude extend deployment flexibility. The MSK061B-0300-NN-M1-UP1-NNNN is particularly suited to automated assembly lines, pick-and-place systems, and high-precision indexing machinery.
