Product Description:

The MSK030C-0900-NN-S1-UP1-NSNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and is part of the MSK IndraDyn S Synchronous Motors series. The model serves as a compact drive element that produces controlled torque and speed for CNC axes, robotic joints, and material-handling gantries in industrial automation. Its small frame and accurate feedback support repeatable positioning in applications where installation space is limited. That combination is useful on short-cycle axes where the controller must command frequent acceleration, deceleration, and stopping without losing positional consistency. The electrical design pairs with IndraDrive controllers, allowing fully digital setup and diagnostics over a single hybrid cable.

Cooling relies on natural convection, so heat dissipates through the aluminum housing without auxiliary fans or liquid circuits. This cooling method keeps the motor layout simple and avoids separate airflow hardware around the housing. A rotatable 240° encoder connector allows the plug position to be adjusted for downward, side, or upward cable exits, which helps when space around the motor is tight. Feedback is transmitted through the Hiperface interface, and position data come from 128 signal periods generated by an optical scanning system. Because the encoder is single-turn, absolute position is resolved within one mechanical revolution, while longer travel is tracked by the drive controller. Winding code 0900 corresponds to coil resistance and inductance values that match standard IndraDrive current outputs.

For load holding during power-off states, an electrically released brake supplies 1 Nm of static torque. The motor uses a shaft with keyway, which provides positive drive engagement for couplings or transmission elements that must resist slip under changing load. Frame size 030 keeps the housing compatible with compact gearheads, while the extended C length adds axial space for the brake stack and the 0900 winding package. This arrangement supports compact automation cells that need secure holding at standstill as well as repeatable motion during normal operation.
