Product Description:
The MSK050B-0450-NN-M1-UG0-NSNN synchronous servomotor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a compact torque source for industrial automation, the unit converts regulated drive current into precise rotary motion for packaging lines, pick-and-place axes, and machine-tool spindles. The size 050 stator and B-length housing help the motor fit confined machine spaces while preserving the fast response expected from this motor family. It connects to compatible drive controllers through a single hybrid cable, which keeps power and feedback routing compact at the machine. This arrangement also helps simplify cable management on moving axes and in densely populated cabinets.
Heat is removed solely by natural convection, so the motor can operate without forced-air ducting when surrounding airflow is adequate. Feedback and power cabling exit through a connector that is rotatable through 240°, allowing the plug direction to be adjusted around nearby hardware. This layout also helps maintain clear access to adjacent connectors and mounting surfaces. Inside the housing, rotor position is measured by a SICK-Stegmann encoder that communicates over the Hiperface channel, which carries parameter data and real-time position information to the drive. Electrical angle is subdivided into 128 signal periods, and the encoder retains position with a multi-turn absolute counting system after power cycles.
The motor supports standard and explosion-protected installations, so the same frame can be used in general factory zones or certified hazardous areas. A plain shaft simplifies coupling to gearheads or timing belts because no keyway is required on the shaft. The motor is supplied without a holding brake, so parked-axis holding must be provided by drive torque or an external device when needed. Encoder sensing is based on optical scanning, which provides high signal quality across the speed range and avoids sensitivity to magnetic noise near surrounding equipment.
