Product Description:

The MSK050B-0450-NN-M1-UG0-NNNN is an IndraDyn S synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. The motor converts electrical input into controlled mechanical motion, supplying tightly regulated torque and velocity for positioning tasks in industrial automation. With a 050 frame size and B length, the device suits compact axes on assembly equipment and material-handling stations that demand repeatable speed tracking and smooth dynamic response. Its compact housing helps it fit installations where axis space is limited.

Heat generated by the stator is dissipated through natural convection, so the installation must leave clearance for free airflow rather than add external fans or liquid circuits. The enclosure has an IP65 rating, which blocks dust ingress and resists water jets during routine washdown. For feedback, the motor incorporates an optical encoder that communicates through the Hiperface interface; its 128 signal periods per revolution provide fine incremental interpolation. Absolute position is preserved by the encoder's multiturn absolute design, allowing the drive to know the shaft angle after power cycles. Electrical routing is simplified by a rotatable 240° encoder connector, which can be turned during mounting to reduce cable strain.

The motor uses a plain shaft, which eliminates keyways and helps reduce backlash in clamp-style couplings. Thermal integrity is supported by insulation class 155, permitting winding temperatures up to 155 °C without dielectric breakdown. Continuous operation is specified for ambient temperatures from 0 to 40 °C, so derating or external cooling is needed only outside that range. The motor has a standard mechanical design, and the 0450 winding identifies the electrical winding version used in this frame size.
