Product Description:

The MSK100C-0300-NN-S2-LG0-RNNN is an AC synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit serves as the primary rotary element in closed-loop industrial axes, converting drive current into accurately regulated torque and speed for packaging machinery, printing lines, and material-handling systems. Its role is to provide high-precision motion where tight positional repeatability and smooth velocity control are required. It is suited to applications that demand stable low-speed operation as well as repeated acceleration and deceleration.

Its cooling system relies on natural convection, allowing the finned housing to dissipate heat without fans or liquid circuits. A design that emphasizes increased concentricity keeps the rotor aligned with the stator centerline and helps reduce magnetic runout during operation. Position feedback is generated through the EnDat2.1 interface, and the internal encoder provides 2048 signal periods with optical scanning for finely interpolated feedback tracks. Because the encoder is a single-turn device, it reports the absolute shaft angle within one revolution, while the controller reestablishes position after a full turn. This arrangement supports precise commutation and removes the need for external feedback hardware.

For mechanical integration, the motor uses a plain shaft, a C-length housing, and size 100 laminations with winding code 0300. It is supplied without a holding brake, so any load that must remain fixed at standstill requires external holding force or controlled drive torque. The enclosure is rated IP65, which helps protect internal parts from dust and low-pressure water spray. The motor can operate in ambient temperatures from 0 to 40 °C, and power is routed through a left-side connector to keep cable exit on one side of the housing. The insulation system meets class 155, supporting the allowable internal temperature rise for this motor design.
