The Bosch Rexroth Indramat MSK101D-0300-NN-S2-LG2-RNNN from the MSK IndraDyn S Synchronous Motors series is a high-performance IndraDyn S Synchronous Servomotor designed for precision motion control. With a compact motor size 101 frame and motor length D, this servomotor delivers robust performance at the rated speed code 0300 rating. Its natural convection cooling system enables maintenance-free operation in environments where forced airflow is not available. Engineered with an increased concentricity design, the unit ensures minimal shaft runout and consistent torque delivery across its operating range.

Integration of advanced feedback systems is achieved through an optical encoder technology with a singleturn encoder turn type, featuring an EnDat2.1 encoder interface and 2048 signal periods resolution for microsecond-level position accuracy. The plain shaft configuration simplifies mounting and coupling to a variety of mechanical loads, while the left-side power connector provides standardized electrical interfacing. Safety and operational readiness are enhanced by the electrically-released holding brake, which supplies a 70 Nm holding brake torque to maintain load position during power-off conditions. Note that this motor requires Cooling FN to meet its full performance specifications, ensuring thermal stability under continuous operation.

At 100 K standstill, the motor can sustain a continuous current of 34.9 A and produce a continuous torque of 57.0 Nm, rising to a maximum current of 137.7 A and a maximum torque of 160.0 Nm for dynamic acceleration demands. The substantial winding inductivity of 3,200 mH contributes to smooth current transitions and low torque ripple, making the MSK101D-0300-NN-S2-LG2-RNNN ideal for high-precision positioning and high-inertia load handling. Compact yet powerful, this servo motor is well suited for robotics, machine tool axes, and industrial automation platforms where accuracy, reliability, and efficient thermal management are critical.
