Product Description:
The MSK076C-0450-NN-S2-UP0-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor supplies precise torque and speed control for positioning axes, pick-and-place modules, and similar automation tasks that rely on direct feedback from an integrated optical encoder. Direct encoder feedback lets the connected drive correct position quickly during acceleration, deceleration, and repeated indexing moves. That makes the motor suitable for applications that need repeatable starts, stops, and short move profiles without losing closed-loop accuracy. Its rotor-stator assembly has increased concentricity for smooth running, and the 0450 winding code is intended for use with a compatible converter.
Heat leaves the housing through natural convection, so no external fan or liquid circuit is required. An IP65 enclosure rating helps protect the motor against dust ingress and water jets, allowing mounting close to the machine. Feedback is provided by an optical encoder with 2048 signal periods per revolution over the EnDat2.1 interface, giving the controller absolute position data with fine resolution. The motor uses a shaft with keyway, which provides positive torque transfer to a matched hub or coupling. Because the motor is supplied without a holding brake, the load must be secured through drive torque or an external brake when power is removed.
The motor has size 076 and length C, which set the flange pattern and stack height for compact machine spaces. The winding uses insulation class 155, supporting winding temperatures up to 155 °C during intermittent overloads. Continuous service is intended at ambient temperatures of 0–40 °C, so the motor can operate in normal industrial surroundings without forced derating. The encoder connector is rotatable 240°, which helps with cable routing when the motor is installed near guards, slides, or adjacent machine members. The compact envelope is useful where motor clearance is limited by guarding or adjacent axes. Single-turn optical feedback keeps position data available within one mechanical revolution and supports fast response in high-cycle positioning tasks.
