Product Description:

The MSK040C-0450-NN-M1-UP1-NSNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is used in industrial automation to convert drive commands from a servo amplifier into controlled rotary motion for positioning or velocity loops on packaging lines, material-handling axes, and similar machinery. The unit’s mechanical code indicates its frame dimensions, winding variant, and feedback package so it can be matched to the torque, speed, and response requirements of the drive system. This makes the motor suitable for compact axes that require repeatable starts, stops, and speed changes during normal machine operation.

Thermal management is handled by natural convection, meaning the frame dissipates heat without fans or liquid circuits. This simplifies installation and reduces maintenance. Feedback is supplied through a connector that is rotatable 240°, allowing cable exit to be aligned with cabinet or carrier constraints. Inside that connector, the encoder transmits position data over the Hiperface serial interface, which carries both absolute position data and motor parameters to the drive. Rotor angle is detected by an optical scanning system that produces 128 signal periods per mechanical revolution, and after interpolation this resolution supports smooth low-speed operation and precise incremental movement.

Because the encoder is a multiturn absolute type, the drive receives unique position information across 4096 mechanical turns without a homing routine after power is restored. For axis holding or emergency stops, an electrically released brake supplies 4 Nm of static torque and engages automatically when control power is removed. The motor frame corresponds to size 040, and its output uses a shaft with keyway design for secure hub-to-shaft coupling. This combination supports applications that need retained position reference after power cycling and controlled stopping when the axis must remain in place.
