Product Description:
The MSK075E-0300-NN-S2-UG2-RNNN servo motor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. Intended for industrial automation, it transforms electrical power into controlled torque and position so packaging lines, pick-and-place robots, and machining centers can execute precise motion paths. Integrated magnets and feedback elements let a compatible IndraDrive amplifier control acceleration, speed, and standstill stability without mechanical backlash. This makes the motor suitable for synchronized axis applications that require quick response and accurate stopping during repeated production cycles.
Heat generated in the windings is removed by natural convection, and the motor uses the FN cooling configuration, so surrounding airflow must remain unobstructed. An increased concentricity design limits shaft runout, and length code E adds active lamination depth without enlarging the flange. That arrangement helps maintain coupling alignment and supports smooth rotation at the load connection. The plain shaft interfaces directly with clamp or keyed hubs, while a rotatable 240° connector simplifies cable routing where space behind the motor is limited. Its optical single-turn encoder supplies 2048 signal periods per revolution, and an electrically released brake provides 30 Nm of holding torque when power is removed. The housing has an IP65 rating, and continuous operation is permitted at ambient temperatures from 0 to 40 °C.
Winding code 0300 identifies the electrical characteristics used by the matching drive for current control. Position data travels through the EnDat2.1 interface, which supports absolute feedback along with integrated diagnostics and electronic nameplate functions. The feedback channel also lets the controller read position information immediately after power-up on compatible systems. Frame size 075 corresponds to a 115 mm installation pitch and the overall mass class used across the series. Insulation class 155 allows the stator to reach 155 °C before thermal aging accelerates. These features support accurate feedback and straightforward integration in medium-power servo axes.
