Product Description:

The MSK050B-0300-NN-M1-UP0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. With a size 050 frame and B-length stator, it delivers closed-loop rotary motion for indexing tables, pick-and-place arms, and other precision axes in automated machinery. Its standard mechanical design supports direct mounting on gearboxes or pulley stages and matches the dimensional envelope commonly used in compact multi-axis assemblies on factory floors.

Thermal management is provided by natural convection, so heat is removed through the housing surface without forced airflow. This allows quiet operation in cabinets where fan capacity is limited. The motor’s single-cable feedback section uses a connector that is rotatable through 240°, allowing the cable exit to be oriented during installation and helping prevent torsion on the conductors. Position data are exchanged with the drive via the Hiperface protocol, and this digital interface combines power and serial communication so fewer conductors are required. Within the feedback head, an optical scanning system generates 128 signal periods, giving the drive controller fine angular resolution for accurate speed and position regulation even at low shaft velocities.

Long-term position information is maintained by a multi-turn absolute encoder, enabling the controller to read shaft angle and revolution count immediately after power-up without a homing routine. The motor is supplied without a holding brake, which reduces mass and eliminates brake release wiring, so static loads must be secured by drive torque or external locks. A shaft with keyway provides positive mechanical coupling and keeps torque transfer secure during start-stop cycles. The stator uses winding code 0300, which gives the electrical resistance and inductance values suited for applications that need moderate continuous current while still supporting rapid dynamic response.
