Product Description:

The MSK050B-0450-NN-M2-UP0-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed as a drive element for precision axes, it uses an integrated encoder to close the position loop with the controller. Frame size 050 and length code B keep the motor compact while still delivering the torque response needed for packaging, handling, and light machining equipment that does not use forced-air or liquid cooling. This arrangement supports accurate speed and position control during repeated indexing and short-cycle motion in compact automation systems.

Its thermal management depends on natural convection, so heat leaves the housing without fans and reduces cabinet complexity. The motor has an IP65 enclosure that blocks dust and low-pressure water jets, supporting direct mounting on open machine frames. Feedback runs through the EnDat2.1 serial interface, and the 240-degree rotatable connector lets cables exit in the required direction. Position data are generated at 2048 signal periods per revolution by the multiturn absolute encoder, allowing position availability immediately after power-up. The connector rotation also helps route cables around nearby machine structures without forcing a sharp bend at the housing entry. The motor ships without a holding brake, so external restraints must secure vertical or suspended loads at rest. Winding code 0450 corresponds to the electrical characteristics used by the matching drive.

The mechanical section uses increased concentricity machining on the mounting flanges to minimize shaft runout for gear or belt coupling. Measurement tracks are scanned by an optical sensor that avoids magnetic drift and supports fine interpolation. Continuous duty is permitted at ambient temperatures from 0 to 40 °C, with insulating materials rated to class 155. Torque is delivered through a shaft with keyway, enabling direct connection to standard pulleys and couplings without additional machining. This shaft form also works well with common keyed transmission components used in compact motion assemblies.
