Product Description:

Bosch Rexroth Indramat's MSK071C-0300-NN-M2-UG1-RNNN is a servo motor in the MSK IndraDyn S Synchronous Motors series. The model supplies finely regulated rotary output for indexing tables, pick-and-place arms, and feed drives that require accurate position feedback and high cycle consistency. Integrated with IndraDrive controllers, it serves as the electromechanical actuator that closes the motion loop and converts electrical commands into torque on the machine shaft for demanding manufacturing and material-processing equipment. This platform fits machines that need compact dimensions together with stable speed regulation during variable load changes. Its closed-loop response also supports repeatable motion in equipment that runs frequent start-stop cycles.

Thermal management depends on natural convection, so heat leaves the stator through the housing fins without auxiliary blowers. An IP65 sealing system keeps dust and low-pressure water jets out, allowing the motor to mount directly on production lines. The electrically released brake delivers 23 Nm of holding torque to secure vertical axes during power loss. Position data travels over the EnDat2.1 interface, and the optical sensor generates 2048 signal periods per revolution. The encoder operates in multiturn absolute mode, so the axis can retain position information after shutdown, and a rotatable 240° connector helps route the feedback cable in the preferred direction. Winding code 0300 matches the electrical characteristics used with 400 V class drives.

The mechanical build follows size 071 with the compact C length, while the rotor end is machined as a plain shaft for rigid coupling to gearboxes or pulleys. The stator lamination stack uses the manufacturer's increased concentricity design, which helps reduce runout and vibration at speed. Continuous service is permitted within an ambient range of 0 to 40 °C, backed by insulation system Class 155 that withstands elevated winding temperatures. Bosch Rexroth lists the product type simply as a servomotor, and the motor is intended for precise positioning and steady speed control in automated equipment.
