Product Description:

The MSK071E-0450-NN-M1-AP1-NNAN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical power into controlled rotary motion for axes that demand repeatable torque and accurate positioning in packaging lines, gantry stages, and material-handling equipment. An integrated optical feedback device supplies precise rotor-angle data to Rexroth drive controllers, enabling closed-loop vector control and tight synchronization among multiple axes.

Thermal management is handled through natural convection, so the housing dissipates heat without external fans or liquid lines, which simplifies enclosure design. The motor has size code 071 and length code E; this geometry sets the flange pattern and stack height that must be considered when the motor is mounted on a machine frame. Power conductors terminate on the A-side of the stator, allowing routing toward the drive cabinet without crossovers in typical left-hand installations. For feedback, the motor uses the Hiperface interface, permitting bidirectional communication of position, temperature, and electronic nameplate data over a single hybrid cable. The winding code 0450 aligns torque and speed characteristics with MSK-compatible inverters, while the reduced runout design minimizes radial error at the shaft.

An optical encoder delivers 128 signal periods per revolution and stores angular position across power cycles through its multiturn absolute design. This resolution supports fine interpolation by the controller for smooth velocity profiles. The output shaft is supplied as a shaft with a keyway, providing positive mechanical engagement with couplings or pulleys while preserving the motor's reduced runout characteristics. An electrically released holding brake supplies 23 Nm of static torque for secure load holding during emergency stops or power loss. The brake releases without residual drag once power is reapplied, protecting dynamic performance.
