Product Description:

The MSK071E-0450-NN-M2-UP0-RNNN is a servo motor built by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servomotor, it converts electrical power into tightly regulated rotary motion for positioning axes, gantries, and process equipment. Used with a compatible drive controller, the motor supports closed-loop motion with accurate speed and position response during changing load conditions. This makes it suitable for automated assembly, packaging, and material-handling stations where repeatable rotary motion is required.

Thermal management is handled through natural convection, so ambient airflow removes waste heat without integrated fans and no separate blower is required on the motor. A housing sealed to IP65 keeps dust and low-pressure water jets away from the stator windings and internal feedback components. Feedback is generated by an optical measuring system that provides 2048 signal periods per revolution, and the data leave the rotatable 240° encoder connector through the EnDat2.1 serial interface for direct numerical position reporting. Because the unit uses a multiturn absolute measuring system, the control system retains position after power loss. Safe operation is permitted in environments between 0–40 °C.

The motor has a frame size of 071 and an axial length code of E. This combination gives it standardized mounting dimensions within the series while keeping the housing suitable for compact machine layouts. The axial build also provides additional active length within the same frame. It uses winding code 0450, which matches the electrical characteristics expected by compatible drive controllers. Insulation class 155 supports continuous operation under normal industrial thermal loads. The output shaft uses a keyway for torque transmission, and the motor is supplied without a holding brake, so the machine must hold the load when power is off.
