Product Description:
Bosch Rexroth Indramat manufactures the MSK071E-0300-NN-S2-UG0-RNNN, and it is part of the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servo motor, the unit pairs with IndraDrive controllers to deliver tightly regulated torque, speed, and position in automated handling equipment, gantry axes, and processing machines. It is intended for closed-loop motion tasks where stable torque delivery and accurate feedback are needed during indexing, positioning, and synchronized movement. The motor’s compact format also supports installation on axes where space around the machine frame and cable path is limited.
The motor uses natural convection to carry heat away from the stator, so mounting must leave clearance for vertical airflow. An internal build with increased concentricity lowers shaft runout and helps maintain repeatable positioning when coupled to precision gearheads. Cable routing is simplified because the feedback connector is rotatable through 240°, reducing strain inside tight enclosures. Position information travels through the digital EnDat 2.1 interface, giving the drive access to electronic nameplate data and direct parameter recognition. The encoder delivers 2048 signal periods, which the control interpolates for high-resolution velocity and position loops.
Feedback accuracy is supported by the encoder’s optical scanning principle. Because it is a single-turn model, absolute position resets after one mechanical revolution and the drive must track rotations beyond that point. The shaft is a plain shaft, allowing direct coupling through clamping hubs without keyways. The motor is supplied without a holding brake, so static load retention must be provided by external mechanics or drive torque. This arrangement suits axes that rely on external holding at standstill.
