Product Description:

The MSK050B-0600-NN-M1-UG1-NNNN is a servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It delivers closed-loop rotary motion for axes that require precise speed and position regulation in packaging lines, pick-and-place robots, and CNC feed drives. An integrated holding brake secures the load at standstill or during power loss. When paired with an IndraDrive amplifier, the motor forms a compact axis that supports fast acceleration while maintaining accurate feedback for responsive automation. This arrangement is well suited to machines that perform frequent starts, stops, and short positioning moves during repetitive production cycles.

The motor housing is cooled by natural convection, meaning heat moves from the surface to the surrounding air without forced airflow, so installations can omit cabinet fans. Its mechanical build follows a standard design with length code B. For feedback, a rotatable 240° encoder connector eases cable routing in confined spaces and helps when the motor must fit into tight machine envelopes. The integrated optical position sensor uses the Hiperface protocol and delivers 128 signal periods per revolution, giving fine interpolation to the drive. Motion is transmitted through a plain shaft, which mates with clamp or keyless couplings to reduce play in the driveline.

The encoder supplies multiturn absolute data, so the drive retains exact shaft position across complete power cycles and no homing routine is needed at startup. During idle or emergency stops, the brake provides 6 Nm of torque to secure the load. The compact frame identified as 050 simplifies mounting on small-footprint machines, while winding code 0600 matches the motor’s electrical characteristics to standard IndraDrive power stages. Because heat is removed passively, duty cycles must remain within the allowable surface temperature limits for convection-cooled models. Within that operating range, the motor maintains repeatable speed and torque response during repeated indexing and positioning moves.
