Product Description:
The MSK071E-0450-NN-M1-UG2-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. With a 071 frame size and E-length stator, the unit fits medium-power axes that cannot accommodate larger housings. Its standard design and fan-free housing support installation inside enclosed machine spaces where external cooling hardware is not preferred. It is intended for servo axes that require compact installation dimensions together with repeatable dynamic response. When paired with a compatible drive, the motor supplies repeatable torque for coordinated positioning, speed control, and cyclic indexing in assembly stations, palletizers, and packaging machines.
The motor uses natural convection, so heat is dissipated through the housing without forced air or liquid assistance. Feedback is carried by a Hiperface interface that sends position and speed data to the drive and also allows parameter storage inside the encoder. Within that system, the optical reader resolves 128 signal periods per mechanical revolution, which supports accurate commutation and stable low-speed control. An electrically released holding brake supplies 30 Nm of static torque to keep loads at rest when power is removed. Mechanical power is transferred through a plain shaft, allowing direct coupling with backlash-free clamp hubs or gearheads.
The encoder connector on this E-length, size 071 frame is rotatable through 240°, so cable outlets can be aligned with cabinet layouts without twisting wires. The rotatable connector also helps route feedback cabling in tight machine compartments. Position feedback remains valid across 4096 revolutions because the encoder is a multi-turn absolute device that preserves count data after shutdown. Its sensing principle is optical, which helps reduce magnetic crosstalk in dense servo installations. The stator winding code 0450 corresponds to the electrical values used by compatible drive controllers for current, torque, and speed limits during closed-loop operation.
