Product Description:
The MSK050C-0300-NN-M3-UG0-NNNN is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It functions as a servomotor for closed-loop torque and position tasks in automated packaging lines, machine tools, and material handling cells. The unit’s electromagnetic construction suits mid-frame axes and integrates with compatible drive controllers in multi-axis assemblies. This layout is well suited to compact servo axes that require stable speed control and repeatable positioning during frequent start-stop motion.
Thermal management relies on natural convection, so the motor dissipates heat through its housing without forced airflow or liquid circuits. The enclosure carries an IP65 rating, preventing dust ingress and protecting against water jets during washdown cleaning. A rotatable 240° feedback plug lets the encoder cable exit in the preferred direction, which helps routing in tight machine spaces. Signal transfer follows the Hiperface protocol. Inside the encoder, capacitive sensing tracks rotor position as multi-turn absolute feedback with 16 signal periods, giving the controller accurate position data across multiple revolutions. Because the motor is supplied without a holding brake, external mechanical locking or drive torque must secure the load when power is removed.
The dimensional code identifies a C-length rotor within the 050 frame size, giving the motor a compact footprint for tightly spaced axes. Winding code 0300 corresponds to electrical values matched to compatible IndraDrive amplifiers. Continuous operation is permissible in ambient air from 0 to 40 °C, which aligns with common factory conditions. Insulation class 155 certifies the winding system for elevated operating temperatures. The motor has a plain shaft that simplifies coupling to gearboxes or timing pulleys and avoids keyseat stress concentrations. This shaft style also supports straightforward connection to external transmission components where a smooth output interface is preferred.
