Product Description:

The MSK050C-0300-NN-S2-UG1-RNNN is an IndraDyn S synchronous servo motor built by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It converts electrical power into precisely controllable mechanical motion for CNC axes, pick-and-place tables, and other closed-loop automation equipment. The motor uses frame size 050 with length code C, giving a compact footprint that fits standardized mounting patterns while still supporting the torque demands of medium-duty production machinery. This frame and length combination works well in compact machine modules where mounting space is limited but accurate axis control is still required.

Thermal management relies on natural convection, allowing the housing fins to dissipate heat without auxiliary blowers or liquid circuits. An electrically released holding brake rated at 6 Nm secures the load during power loss and helps prevent drift when the axis is idle. Feedback signals leave through a rotatable 240° encoder connector, which simplifies cable routing in tight cabinets or around adjacent machine parts. Position data are transmitted over the EnDat 2.1 interface, and the optical scale provides 2048 signal periods per revolution, giving the drive controller fine interpolation capability. The mechanical design uses increased concentricity to reduce radial runout at the coupling flange and support smooth motion across the speed range.

The feedback system uses optical scanning and a single-turn code track, so absolute position within one revolution is available without a battery. A plain shaft couples directly to clamping hubs or shrink disks, reducing backlash that can come from more complex mechanical interfaces. The electromagnetic core follows winding code 0300, balancing resistance and inductance for rapid torque buildup on 400 V class inverters. That winding arrangement supports repeated cycles with stable control behavior and helps the motor respond quickly to changing command values.
