Product Description:

The MSK050B-0450-NN-M2-UG1-RNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated assembly cells, pick-and-place gantries, and packaging machines, it delivers precise torque and speed so a connected drive controller can position mechanical axes quickly and repeatably. The motor combines permanent-magnet excitation with a compact frame to convert electrical input from an IndraDrive inverter into controlled rotary motion for industrial tasks. That combination supports accurate indexing, synchronized transfer moves, and short settling times in equipment that cycles continuously.

Heat is removed by natural convection, so external fans or liquid cooling plates are not required. Because no auxiliary cooling hardware is needed, installation remains simpler in compact machine sections where airflow is limited. The 0450 winding is matched with the B-length stack and 050 frame, giving the motor operating characteristics suited to precise servo duty. An optical encoder uses the EnDat2.1 serial interface and provides 2048 signal periods of base resolution, while the multi-turn absolute feedback system retains position information across multiple revolutions without a battery. This arrangement lets the drive read fine position changes for commutation and controlled speed regulation. For holding a stopped axis, the electrically released brake provides 6 Nm of retention torque.

The housing has an IP65 rating, which protects internal windings from dust and low-pressure water jets during routine washdown. Power is transmitted through a plain shaft that accepts force-fit couplings without keyways, which helps reduce backlash in high-cycle assemblies. Continuous operation is intended for ambient temperatures from 0 to 40 °C, and Class 155 insulation helps protect the copper windings from thermal stress within that range. The increased-concentricity design reduces shaft runout, which supports accurate coupling alignment and smooth motion in precision axes. The sealing and shaft arrangement suit direct coupling to machine elements that need reliable alignment and resistance to everyday industrial contamination.
