Product Description:

The MSK075D-0300-NN-M2-UG1-RNNN synchronous servomotor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical drive commands into continuous rotary motion for accurate positioning and speed control in automated machinery. Its frame size 075 and length D place it in the mid-torque range needed by general-purpose servomechanisms across packaging lines, gantry axes, and material-handling stations. It is intended for axes that need repeatable motion during positioning, speed changes, and dwell periods. This operating role also suits synchronized indexing, feed control, and other servo-driven machine functions.

Cooling is handled by natural convection, eliminating the need for forced-air accessories and simplifying cabinet layout. The motor’s feedback package combines an optical scanning assembly with an EnDat 2.1 digital interface, so the system receives closed-loop updates without additional analog wiring. Within the measuring head, the glass disk provides 2048 signal periods, and the multi-turn counter stores absolute position data as multi-turn absolute feedback. Digital position data from the encoder allows the paired drive to track rotor angle directly during motion control. Because the disk is scanned optically, magnetic stray fields from nearby drives do not degrade resolution or introduce offset errors. The feedback connector is rotatable through 240°, which helps with cable routing in tight machine frames.

The stator uses winding code 0300, and the rotor has increased concentricity, so radial runout remains low during high-speed interpolation. An electrically released holding brake produces 23 Nm of torque to secure vertical loads when the drive is disabled. Mechanical power is transmitted through a plain shaft, allowing rigid couplings or pulleys without keyways. This shaft style is commonly used where torque is transferred by clamp couplings or belt-driven elements.
