Product Description:

Bosch Rexroth Indramat manufactures the MSK030C-0900-NN-S1-UP0-NSNN servo motor as part of the MSK IndraDyn S Synchronous Motors series. The unit is an AC servo actuator intended to generate precise, closed-loop torque and speed in automated machinery such as pick-and-place axes or compact packaging lines. Within an automation cell, it converts electrical drive commands into rotational movement and pairs with IndraDrive controllers through its integrated feedback interface.

The motor has size 030 and length C, providing a compact footprint while accommodating the stator stack for winding code 0900, which sets the voltage constant and current limits expected by the drive. Heat is dissipated solely by natural convection, so airflow around the housing must remain unobstructed. An enclosure rating of IP65 blocks dust ingress and water jets, allowing mounting outside a cabinet as long as the ambient remains within 0–40 °C. The motor uses insulation class 155, so the windings can operate continuously up to 155 °C without loss of dielectric strength. Because this version is supplied without a holding brake, mechanical locking or drive torque must hold position during power-off.

The feedback stage uses a Hiperface interface that carries power and bidirectional data between the drive and the sensor package. Inside the motor, an optical single-turn disk yields 128 signal periods, supplying absolute rotor position for one revolution, while higher resolution is synthesized in the controller. The feedback plug can be rotated 240 degrees, which simplifies cable routing in tight panels. Mechanical power leaves the unit through a shaft with keyway, enabling positive-fit coupling to pulleys or gearboxes. Standard housing construction is approved for explosion-protected zones when ordered with the appropriate certification, and the absence of active cooling hardware helps keep overall mass low.
