Product Description:
The Bosch Rexroth Indramat MSK075C-0300-NN-M2-UP0-RNNN is an AC synchronous servo motor in the MSK IndraDyn S Synchronous Motors series. It is intended for precision motion axes where compact size, integrated feedback, and dependable thermal behavior are necessary. The design supports accurate positioning and stable speed control in automated machinery that runs repeated motion cycles.
The motor relies on natural convection cooling, so heat leaves the housing through its surface without fans or liquid circuits. Its enclosure is rated at IP65, which keeps dust and water jets away from the stator windings and optical feedback hardware. Position data is generated by an encoder that provides 2048 signal periods per revolution, giving fine incremental resolution for speed loops. Drive communication uses the fully digital EnDat2.1 interface, which supports bidirectional parameter transfer and error reporting. Continuous operation is permitted at ambient temperatures of 0–40 °C, and the winding remains within its allowed thermal range during normal use. Additional features include increased concentricity to reduce radial runout, optical sensing technology for stable signals, a multi-turn absolute count that retains position after power loss, and a connector that can be rotated to simplify cable routing. Frame size 075 and length C place this model in mid-range servo applications.
A shaft with keyway provides positive torque transmission to couplings, while the stator insulation is rated at Class 155, which supports winding hot-spot temperatures up to 155 °C during peak duty. The encoder plug is rotatable through 240°, so the cable can be directed toward cabinet glands without twisting conductors. Electrical characteristics follow the 0300 winding code, aligning the back EMF constant with compatible IndraDrive amplifiers. The motor is supplied without a holding brake, so external clamps or gear mechanisms must secure load position during standby, while the absolute feedback system continues to record each shaft revolution for accurate restart alignment.
