Product Description:

The MSK050C-0300-NN-S2-UG0-RNNN is a servo motor built by Bosch Rexroth Indramat and supplied as part of the MSK IndraDyn S Synchronous Motors series. It converts drive current into rotary motion for positioning duties in automated machinery, packaging axes, and handling gantries. In integrated motion systems, it works with a compatible drive to provide closed-loop torque and speed control. This makes it suitable for axes that require repeatable starts, stops, and speed changes during normal machine cycles.

Cooling is handled by natural convection, so heat leaves the housing without external fans and the motor should be mounted where air can circulate freely. The feedback plug is rotatable through 240°, which helps route cables in confined machine layouts. Rotor position data are transmitted over the digital EnDat2.1 interface, and the encoder uses an optical scanning system with 2048 signal periods per mechanical revolution for precise feedback processing. Bidirectional communication also allows the drive to exchange electronic data with the feedback system during operation. Length code C indicates a longer active lamination stack, which supports higher continuous torque without changing the external frame size.

The motor uses the increased concentricity option, which helps maintain accurate shaft running characteristics for couplings and gearheads. Feedback is single-turn, so the absolute position repeats after one shaft revolution and is suitable for equipment that references at startup. Mechanical power is transmitted through a plain shaft, which supports direct coupling arrangements where low backlash is important. The motor is supplied without a holding brake, so static holding must be provided externally. That arrangement is often used where the axis is secured by another mechanical holding method when power is removed. Size code 050 and winding code 0300 identify the mounting format and electrical winding used for this version.
