Product Description:

Bosch Rexroth Indramat builds the MSK075D-0300-NN-S1-UP0-NNNN for inclusion in the MSK IndraDyn S Synchronous Motors series. The unit is an IndraDyn S synchronous servo motor that converts drive current into precise rotary motion for automated axes, packaging machinery, and material-handling gantries. Its D-length frame, 075 size code, and standard mechanical design provide a mid-range torque option for systems that already use this mounting pattern. In closed-loop operation, the motor supports accurate positioning during starts, stops, and speed-controlled motion.

The stator is cooled by natural convection, so the housing must be positioned to allow free ambient airflow instead of relying on fans or liquid circuits. A factory-installed feedback connector that is rotatable through 240° allows flexible cable routing without sharp bends at the motor. Position data travel over the Hiperface serial protocol, allowing simultaneous transmission of commutation, identification, and diagnostic information to the drive controller. The encoder uses optical scanning and outputs 128 signal periods per revolution, balancing resolution with moderate data volume for real-time motion loops. The unit reports rotor angle on a single-turn basis, which is suitable when the axis uses a homing routine or an external reference switch after startup. This motor ships without a holding brake, so vertical or suspended loads must be secured by external means when power is removed.

Mechanical output passes through a shaft with a keyway, which helps transmit cyclic torque to couplings, pulleys, or gear inputs without slip. The motor size of 075 matches the standard flange pattern used for this frame, so the housing fits common machine interfaces without adapter plates. Winding code 0300 identifies the electrical winding matched to IndraDrive controllers, and that winding affects current draw, voltage use, and the practical speed range. Motor length D extends the active core to raise continuous torque compared with shorter versions, while the standard housing design remains compatible with common sealing arrangements.
