Product Description:

The MSK071C-0200-NN-M2-UG1-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat and delivered within the MSK IndraDyn S Synchronous Motors series. As a drive element, it supplies closed-loop torque and speed control to machinery that relies on precise electrical positioning, such as pick-and-place axes or compact machining centers. The unit’s size 071 stator frame and length code C provide a medium power envelope, while the 0200 winding code matches the coil impedance to moderate-voltage IndraDrive controllers. A factory-installed electrically released holding brake allows the motor to support static loads when system power is removed. This operating profile is common in packaging, handling, and other automated stations that require repeatable motion.

The motor rejects heat to ambient air through natural convection, so no external fan or liquid manifold is required. Its rotor and stator are ground to an increased concentricity tolerance, which helps limit radial runout that could introduce vibration into high-precision mechanisms. Feedback wiring exits through a connector that is rotatable through 240°, simplifying cable routing inside tight enclosures and allowing better alignment with cabinet entry paths. Position data is transmitted over the EnDat2.1 bidirectional digital interface, and the optical scale supplies 2048 signal periods per revolution before interpolation by the drive. This encoder arrangement supports fine incremental motion and electronic nameplate storage without separate reference switches or homing routines in many applications.

The encoder uses an optical scanning method and is built as a multi-turn absolute sensor, so it reports shaft angle and up to 4096 mechanical turns after power cycling. The electrically released brake supplies 23 Nm of static torque, adding holding force for vertical or indexing loads during stops. Mechanical power is transmitted through a plain shaft, which avoids keys that can concentrate stress in servo couplings. This shaft form suits clamp-style couplings commonly used on servo axes. The encoder can also restore position information after a restart without requiring the machine to return to a reference point.
