Product Description:

The MSK050B-0600-NN-M2-UG1-RNNN is a servo motor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. This synchronous servomotor converts electrical energy into controlled rotary motion for precise position and speed regulation in packaging axes, gantry drives, and material-handling systems. Its compact layout combines feedback, torque transmission, and heat dissipation in one housing, which helps it fit into multi-axis machine designs with limited installation space. It is intended for closed-loop automation tasks where the drive must respond quickly to changing commands and varying load conditions.

The stator uses winding code 0600 and corresponds to a size 050 frame with B length. Cooling relies on natural convection, so heat leaves through the motor housing without fans or liquid circuits. Position data come from an optical encoder with 2048 signal periods per revolution, and the feedback connection uses a rotatable 240° connector so the cable outlet can be adjusted for tight cabinet layouts. Data are transmitted through EnDat2.1, and a multi-turn absolute encoder retains shaft position through 4096 mechanical revolutions. This arrangement gives the drive both fine position resolution and retained turn information across extended travel. An electrically released holding brake provides 6 Nm of torque when the axis must remain stationary after power is removed.

Mechanical power is transferred through a plain shaft that accepts clamp couplings or keyless hubs, since no keyway is machined into the shaft. The housing has an IP65 rating, which keeps out dust and protects against water jets encountered around coolants or washdown spray. Continuous operation is permitted in ambient temperatures of 0–40 °C, provided the motor has enough surrounding space to release heat from the frame surface. Because cooling is passive, nearby machine structures should not block airflow around the outer housing. Shielded power and feedback cabling help preserve signal quality, and accurate shaft alignment helps the motor maintain stable motion over repeated cycles.
