Product Description:

The MSK075E-0300-NN-M2-UP0-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for axes that need fast response and accurate positioning in automated production cells, packaging machines, and CNC systems. By combining torque production with integrated optical feedback, the motor gives the connected drive continuous position data so commanded motion can be converted into stable, repeatable shaft movement. This arrangement supports closed-loop operation where speed changes, short positioning moves, and directional reversals must remain controlled under changing load conditions.

Heat generated during operation is removed by natural convection, so no external blower or liquid circuit is required. This cooling method keeps the installation simple and allows the motor to operate without separate airflow hardware around the frame. The feedback connection uses a 240° rotatable connector, which helps route cables in confined machine spaces without forcing a fixed outlet direction. Signal transmission is handled through the EnDat2.1 interface, and the optical system provides 2048 signal periods per revolution for accurate feedback. The encoder uses a multi-turn absolute design, so position remains available across multiple shaft turns after startup.

The motor is supplied without a holding brake, so static load holding must be handled by the drive or external mechanics when the axis is stopped. The housing is sealed to IP65, which helps keep dust and low-pressure water jets away from internal components in normal industrial service. It is intended for ambient temperatures from 0–40 °C, and insulation class 155 supports elevated winding temperature during operation. A keyed shaft provides positive torque transfer to the driven element, while the E-length housing, 075 frame, 0300 winding code, and increased concentricity support smooth running and compatibility with matched drive data.
