Product Description:
The MSK071E-0300-NN-S1-UG2-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and used in the MSK IndraDyn S Synchronous Motors series. It converts current from an external inverter into accurate rotary motion for industrial automation axes that require high positioning accuracy and rapid cyclic operation. Integrated feedback allows the connected drive to monitor rotor position continuously, which supports smooth interpolation and repeatable stop positions during demanding motion sequences. An electrically released holding brake also helps the axis remain in place when power is removed, making the unit suitable for material-handling gantries, feeders, and small press stages.
The motor uses Natural convection cooling, but the FN cooling designation means surrounding cabinet airflow must still be available around the housing. Frame code 071 identifies the motor size, while length code E gives a longer stack for higher continuous torque without changing the basic mounting footprint. Winding code 0300 matches the electrical characteristics expected by compatible MSK drives. The motor has a Plain shaft, so torque is transferred through a suitable hub or other friction-based connection. This layout keeps the installation straightforward while preserving a compact motor envelope for tightly arranged machine axes.
The rotatable 240° encoder connector helps with cable routing in confined installations, and the feedback interface is Hiperface for combined position and electronic data exchange. The encoder uses Optical scanning with 128 signal periods, and the single-turn format reports absolute position within one motor revolution. An electrically released holding brake provides 30 Nm of static torque, which is useful on vertical axes or in applications where the load must stay in place after power is removed. The connector arrangement can also reduce cable strain during installation, and the high signal quality supports stable speed and position control with the paired drive.
