Product Description:

The MSK075D-0300-NN-S1-UG0-NNNN is a synchronous servo motor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop industrial axes where precise speed and torque regulation are required in packaging lines, assembly cells, and material handling equipment. As part of a drive system, it converts commanded current into controlled rotary motion, while its integrated encoder keeps the axis synchronized with the motion controller. This arrangement supports repeatable positioning during rapid starts, stops, and direction changes throughout normal machine operation.

Thermal management is handled by natural convection, eliminating the need for external fans. The housing uses a standard mechanical design that fits the MSK mounting pattern. Frame size 075 pairs with length code D to give the motor its basic stator geometry and active stack length. Winding code 0300 identifies the turns per phase and matches the motor to appropriate IndraDrive current ratings. The motor uses a plain shaft for backlash-free connection to couplings or timing pulleys, and it is supplied without a holding brake for applications that rely on external clamping or drive torque to maintain position.

Position feedback is supplied by an optical single-turn encoder that communicates through Hiperface. The scanning disk generates 128 signal periods per mechanical revolution, giving the controller fine angular resolution without relying only on incremental counting. For flexible cable routing, the feedback connector is rotatable through 240°, so the plug can be turned toward the preferred cable exit direction while maintaining proper bend routing. Optical sensing resists magnetic interference, and the single-turn encoder structure stores one absolute rotation, which suits rotary tables, print cylinders, and indexing arms that do not travel through multiple turns between homing cycles.
