Product Description:

The MSK075D-0300-NN-M1-UG1-NNNN is an IndraDyn S synchronous servomotor from the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. Acting as a closed-loop drive element, the motor converts electrical power into precisely metered rotary motion for positioning, feeding, and contour-following axes in industrial automation lines. A standard mechanical design keeps mounting flanges, foot patterns, and pilot diameters consistent across the series.

Natural convection means the housing dissipates heat without external fans or liquid circuits, which helps keep the motor compact. The ingress protection rating of IP65 seals the stator body against dust and low-pressure water jets, so cabinet placement is not mandatory. Within an ambient range of 0–40 °C, the Class 155 insulation helps protect the windings during normal operation. An electrically released holding brake delivers 23 Nm of static torque, securing vertical loads during power-off and supporting safe stopping. Feedback is handled through the Hiperface serial interface; the optical encoder generates 128 signal periods per revolution for fine interpolation and closed-loop speed control while also providing absolute angle data to the controller.

To ease installation, the circular power and feedback plug can be rotated through 240°, allowing the cable exit to align with machine layouts and reducing harness strain. Multiturn counting is provided by the encoder, and its absolute position memory spans multiple revolutions for homing-free startup, a feature identified as multiturn absolute. Mechanical dimensions follow size code 075 and length code D, which establish the stator stack height, shaft extension, and thermal mass suited to medium-frame machinery. The winding identification 0300 matches the motor with drive parameters such as voltage constant and current limit, so the controller can energize the coils within their thermal range.
