Product Description:

Bosch Rexroth Indramat manufactures the MSK071D-0202-NN-S3-UG0-NPNN. It is an IndraDyn S synchronous servomotor in the MSK IndraDyn S Synchronous Motors series. The unit provides controlled torque and speed for automated axes, allowing direct connection to digital drive controllers for positioning, contouring, and material-handling duties. It is suitable for indexing tables, feed axes, and transfer systems that require repeatable rotary motion.

The motor uses natural convection for heat dissipation, so no external fan or coolant circuit is required when the ambient temperature stays within 0–40 °C. Its aluminum housing is rated IP65, which keeps dust out and protects the stator against low-pressure water jets. A B5 flange assembly aligns the case on a machine wall, and the 071 frame size fits standard IEC layouts while leaving room for the plain shaft to couple with gearboxes or pulleys. Length code D extends the active lamination stack, which allows higher continuous torque without enlarging the frame. The motor uses Class 155 insulation and is supplied without a holding brake, so position retention must be achieved electrically through the drive. The sealed housing and self-cooled layout also help the motor fit enclosed machine sections where external cooling hardware would take additional space.

A rotatable 240° connector allows the cable exit to suit cabinet routing, and the encoder communicates through Hiperface. Its signal is produced by a capacitive sensing element that resolves rotor position to 16 signal periods per revolution. Because it is a single-turn device, the absolute position reference is retained over 360° without batteries. Winding code 0202 indicates the electrical resistance and inductance values expected by the drive, helping current loops remain stable at full load. The rotatable connector also helps when cable routing must avoid tight bends near the motor housing.
