Product Description:

The MSK050B-0300-NN-M3-UG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is an IndraDyn S synchronous servo motor, so it operates in step with the stator field to supply consistent torque in automated assembly stations, pick-and-place units, and other motion tasks. Motor size 050 and length code B indicate a compact housing that integrates easily with matched drive controllers while maintaining the standard mechanical outline used across the series. This layout supports installation where axis space is limited but stable servo response is still required.

Its feedback equipment uses a Hiperface interface, allowing digital position data to pass directly to the drive. The integrated encoder uses capacitive sensing technology and provides 16 signal periods per revolution, so the controller receives position information for smooth commutation and steady speed regulation. Absolute position is retained through a multiturn absolute tracking method, removing the need for homing after power loss. For flexible cable routing within tight cabinets, the encoder connector is rotatable by 240°, letting the plug be turned to the most accessible angle without placing unnecessary stress on the conductors.

The mechanical side follows the standard series design and uses natural convection for cooling, eliminating forced-air components that could add noise or maintenance. The motor has an IP65 rating, so internal components remain protected against dust and low-pressure water jets when the unit is properly mated to matching connectors. It is intended to run in ambient temperatures from 0 to 40 °C, and its output shaft is a plain shaft that couples directly to clamping hubs or rigid couplings without a keyway. The motor is supplied without a holding brake, and its thermal insulation class 155 supports the stated temperature limit during normal operation.
