The Bosch Rexroth Indramat MSK071E-0300-FN-M2-UG0-RNNN from the MSK IndraDyn S Synchronous Motors series defines a new benchmark in servomotor design by combining a compact Motor Size 071 frame with an E length housing and a plain shaft configuration. Engineered as an IndraDyn S Synchronous Servomotor, this unit uses liquid cooling to maintain optimal thermal stability under heavy-duty cycles. Its advanced optical encoder technology with a rotatable, 240° encoder connector ensures flexible mounting, while the EnDat2.1 encoder interface delivers high-speed bi-directional data transfer. Rated speed code 0300 aligns this motor with medium-speed applications requiring precise motion.
The MSK071E-0300-FN-M2-UG0-RNNN offers an impressive continuous current at standstill of 15.2 A and sustains a continuous torque at standstill of 28.0 Nm at 100 K for intensive holding tasks. Dynamic performance peaks are equally notable, with a maximum current of 56.3 A and a maximum torque of 84.0 Nm available for rapid acceleration and load changes. Fine motion control is further enhanced by an encoder resolution of 2048 signal periods and a multiturn absolute encoder turn type, guaranteeing repeatable positioning across extensive travel ranges. A high winding inductivity of 5,900 mH smooths current transitions, reducing torque ripple and improving system stability.
Built without a holding brake, the motor’s increased concentricity design minimizes vibration and bearing loads, extending service life in continuous-operation environments. The absence of a brake reduces inertia and simplifies mechanical integration, making this servomotor ideal for precision indexing tables, rotary axes, and multi-axis robotics. Seamless compatibility with standard drive controllers and the proven reliability of the MSK series ensure rapid commissioning and sustained uptime in demanding automation systems.
