Product Description:

The MSK071D-0300-NN-S1-UG1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within automated production cells, the unit converts drive current into precisely regulated rotary motion, allowing coordinated axes to position tooling, conveyors, and pick-and-place heads. Its plain output shaft mates directly with couplings or gear stages, and the integrated single-cable encoder system delivers absolute position feedback to the matching IndraDrive controller for closed-loop velocity and torque control. This arrangement helps reduce external cabling and keeps the motor suitable for compact axis layouts where routing space is limited.

Thermal management relies on Natural convection, so the housing fins must remain exposed to ambient air without forced fans. An electrically released holding brake supplies 23 Nm of static torque, helping prevent load drift when power is removed. Position information travels through the Hiperface serial interface, and the rotatable 240° connector allows the plug to exit in multiple directions for easier cable routing. Frame size code 071 indicates the motor’s outer stator diameter, while winding designation 0300 matches the coil resistance and inductance to the expected drive current range. The motor uses a standard mechanical design, so no special shaft seals or explosion-proof features are included.

The optical feedback stage resolves 128 signal periods per revolution, and the Optical scanning principle supports precise interpolation by the drive. Because the encoder is Singleturn, the absolute position value applies within one shaft rotation and is available immediately after startup. Motor length D increases the active iron depth for higher continuous torque without changing the frame diameter. The plain shaft arrangement also supports direct coupling alignment in tight assemblies, and the longer active section helps increase torque output without requiring a larger frame size.
