Product Description:
The MSK070C-0450-NN-S1-UG0-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The motor converts controlled electrical power into rotary motion for positioning and speed-regulated duties in automated machinery. Its output shaft couples directly to gearboxes, ball screws, or timing pulleys, allowing the drive system to achieve precise closed-loop motion with minimal lost motion in the drive train. In compact packaging lines or pick-and-place stations, this unit supplies the dynamic torque needed for repeatable cycle times and accurate axis response.
The motor relies on natural convection for thermal management, so heat leaves the aluminum stator housing through surface radiation and ambient airflow instead of forced fans. Its power and signal connector is rotatable through 240°, which eases cable routing in tight cabinets and crowded machine frames. Position feedback is handled by an incremental-absolute sensor that generates 128 signal periods per mechanical turn. The fine line pattern is read using an optical scanner for high interpolation accuracy. This transducer is a single-turn device, meaning absolute position is resolved once per revolution and is well suited to short-stroke axes that return to a reference position after each cycle. The sensor communicates over the Hiperface serial protocol to the drive.
The motor has a frame size code of 070 and a length code of C, giving a mid-size footprint that fits inside standard machine frames. It has a plain shaft, enabling clamp hubs or shrink-fit couplings without keyway stress concentrations. The motor uses winding code 0450, which matches its electrical characteristics to 400 V inverter modules for balanced current density. The design is standard, and the motor is delivered without a holding brake, so static load retention must be provided externally. It is intended for coordinated multi-axis tasks in printing, packaging, and electronic assembly.
