Product Description:

The MSK075C-0300-NN-S2-UG0-RNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It uses frame size 075 with length C, placing it in the middle of the range for general-purpose motion tasks. In automated assembly cells and packaging lines, it converts drive current into tightly regulated torque and speed for precise axis positioning on digital drive systems. This layout makes it suitable for applications that need repeatable motion, compact installation, and stable closed-loop control.

As an IndraDyn S synchronous servomotor, the unit relies on natural convection to remove heat from the stator, so no forced air or liquid cooling is required. The housing is sealed to IP65, helping keep dust and water jets away from the internal windings, while the increased concentricity design helps reduce radial runout for improved coupling accuracy. Digital feedback is transmitted through the EnDat 2.1 interface, and the optical scanning system generates 2048 signal periods per mechanical revolution to support smooth velocity control and accurate position feedback. The feedback system uses optical sensing, which helps maintain stable calibration across temperature changes, and thermal insulation class 155 supports the allowable winding temperature for normal operation.

Cable routing is simplified by an encoder connector that is rotatable through 240°, allowing the exit direction to be adjusted for tighter cabinet layouts. Position information is available as a single-turn measurement, which is suitable when multi-turn tracking is handled by the drive. The motor operates at ambient temperatures from 0 to 40 °C without derating and is supplied without a holding brake, so any static load holding must be provided by an external mechanism. A plain shaft supports direct coupling to gear stages or belt pulleys while helping keep vibration low.
