Product Description:

The MSK071C-0200-FN-M1-UG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In industrial automation, this motor functions as a rotary actuator that delivers position and velocity control to machine tools, packaging lines, and handling systems when paired with an IndraDrive controller. The unit follows the IndraDyn S platform, allowing compact integration while supporting closed-loop feedback for precise dynamic motion. In typical servo applications, the motor works with the drive’s current and feedback loops to maintain smooth acceleration, stable speed, and repeatable stopping accuracy as load conditions change.

To manage thermal load, the motor employs liquid cooling, which removes heat directly from the stator housing and permits higher continuous torque within the 0–40 °C ambient range. Position feedback is provided via a Hiperface optical encoder that outputs 128 signal periods per mechanical revolution, and this resolution works with drive interpolation to support fine incremental positioning for contouring tasks. The encoder is a multiturn absolute design, so the controller receives shaft position information across multiple turns without homing after power loss. Cable routing is simplified because the encoder connector is rotatable, 240°, allowing the connection to be aligned with surrounding machine space, and the motor uses winding code 0200 for electrical matching within the 071 frame size.

For plant reliability, the housing carries an IP65 protection rating, preventing dust ingress and withstanding low-pressure water jets when the companion connectors are sealed. Mechanical coupling is straightforward thanks to a plain shaft, which is suited to clamping or shrink-fit hub components. When the mating parts are selected correctly, the shaft interface can be used with couplings, pulleys, or gearbox inputs commonly found on servo-driven machinery. Because the rotor is supplied without a holding brake, the axis must rely on external locking devices or drive-generated torque to maintain position during shutdown.
