Product Description:

The MSK075D-0300-NN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor is used in precision motion axes where closed-loop positioning and repeatable torque delivery are required in automated assembly stations, pick-and-place gantries, and packaging machines. Its compact housing integrates the windings, feedback system, and mechanical elements, allowing direct coupling to gearboxes or load shafts while keeping the drive layout straightforward.

The stator corresponds to size 075 and length code D, which gives the magnetic stack the surface area needed for medium-power tasks. Cooling relies on natural convection, so fins on the outer jacket dissipate heat without forced airflow and allow the motor to operate inside sealed machines. A plain shaft is supplied for backlash-free clamping hubs. Winding code 0300 indicates the copper fill and impedance matched by the connected drive. Position feedback is transferred over the EnDat2.1 serial interface, which carries absolute position and diagnostic data through a single shielded cable. The encoder connector can be turned 240 degrees to route cabling away from adjacent components and help maintain proper bend radius.

The optical encoder resolves rotation into 2048 signal periods, and its optical scanning principle offers high noise immunity during rapid indexing. Because the measuring system is single-turn, it reports one mechanical revolution with 1 arc-second interpolation accuracy, which is suitable for most point-to-point axes when a home reference is restored after power cycling. The motor is delivered without a holding brake, so static position retention must be handled by drive torque or an external locking device. Increased concentricity in the rotor assembly minimizes runout and supports smooth coupling to the driven load.
