MSK071E-0300-NN-M2-UP0-RNNN

The MSK071E-0300-NN-M2-UP0-RNNN from Bosch Rexroth Indramat is part of the MSK IndraDyn S Synchronous Motors series and represents the latest evolution in high-performance industrial servomotors. This IndraDyn S Synchronous Servomotor features a motor size 071 frame with a precise motor length E and a winding code 0300 that ensures optimized electromagnetic characteristics. Designed for applications requiring robust mechanical stability, the motor incorporates an increased concentricity design and a shaft with keyway for secure coupling. The unit is supplied without a holding brake, simplifying integration where unbraked shafts are preferred.

Its electrical performance is characterized by a continuous current at standstill 100 K of 15.2 A and a continuous torque at standstill of 28.0 Nm, supporting sustained load holding without thermal overload. When peak demands arise, the motor delivers a maximum current of 56.3 A and a maximum torque of 84.0 Nm, making it suitable for dynamic positioning and inertia-intensive processes. The winding inductivity of 5,900 mH provides stable current control, reducing ripple and enhancing low-speed smoothness. Integration is further simplified by the absence of internal holding brake circuitry and a compact outline for tight cabinet layouts.

Feedback and monitoring are handled by an optical encoder technology with a multiturn absolute turn type, offering 2048 signal periods resolution and an EnDat2.1 encoder interface. The rotatable encoder connector (240°) allows flexible routing in constrained spaces, reducing assembly time. Cooling is achieved via natural convection and can be augmented with an optional fan unit for high-duty installations. This combination of precise feedback, robust torque capability, and streamlined design makes the MSK071E-0300-NN-M2-UP0-RNNN ideal for advanced servo systems in automation, robotics, and precision machining.
