Product Description:

The MSK075E-0300-NN-S1-UG0-NNNN is an AC servomotor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit converts electrical drive commands into controlled shaft torque and speed for pick-and-place gantries, conveyor indexing sections, and automated packaging stations where precise rotary positioning under closed-loop control is required. Its plain shaft couples directly to gearheads or belts, and the sealed housing allows installation in general factory environments without additional enclosures. In typical automation systems, it works with a compatible servo drive that regulates current, speed, and position from the motor feedback system.

The motor relies on natural convection for thermal dissipation, so unobstructed airflow is required around the housing. Its encoder connector can rotate through 240°, which helps with cable routing where adjacent components limit access. Digital feedback travels over the Hiperface protocol between the motor and the drive. The code disk provides 128 signal periods, and the feedback system uses a single-turn design that reports an absolute position within one shaft revolution. Optical sensing is used for position detection, while the standard design, size 075, length code E, and winding code 0300 identify the motor configuration used for this model.

The motor is delivered without a holding brake, so a stopped load must be secured by the drive or by external machine hardware when power is removed. The housing is rated IP65, which helps keep dust and low-pressure water jets away from internal components. Continuous duty is permitted from 0 °C to 40 °C, allowing operation in normal industrial ambient conditions. A class 155 insulation system supports elevated winding temperatures that can occur during frequent acceleration and deceleration. This arrangement suits indexing tables, loaders, and auxiliary axes that need repeatable motion and straightforward integration into general automation equipment.
