Product Description:
Bosch Rexroth Indramat manufactures the MSK071C-0450-NN-M3-UP0-NNNN as part of the MSK IndraDyn S Synchronous Motors series. This IndraDyn S synchronous servo motor delivers precise rotary positioning and speed control for CNC machinery, packaging stations, and automated assembly lines. The unit follows a standard mechanical design and is built in motor size 071 with length code C. Its permanent-magnet rotor works with a drive-optimized winding layout to provide high torque density in space-restricted installations. That combination suits indexing, feed, and transfer axes that require quick response in a compact installation envelope.
The motor is cooled by natural convection, so housing fins remove heat without fans or external liquid circuits. A protection rating of IP65 seals the stator against dust ingress and low-pressure water jets, permitting mounting near the machine process area without a separate cabinet. Feedback signals travel through the Hiperface interface, and the embedded encoder outputs 16 signal periods per revolution, giving the drive controller fine incremental data for smooth vector control. The rotatable 240° encoder connector helps route cables in crowded machine spaces and supports flexible connector orientation during installation. A shaft with keyway secures couplings against slip, while the motor is supplied without a holding brake, so static loads must be retained by mechanical locking devices or drive torque.
The encoder operates on a capacitive sensing principle and stores position across power cycles by using a multiturn absolute counting scheme. This arrangement allows the control system to retain position information after shutdown and restart. Continuous duty is specified for ambient temperatures between 0 to 40 °C, allowing the motor to share space with nearby control equipment without forced cooling. Windings use insulation class 155, which supports elevated internal temperatures before thermal aging becomes a concern. Winding code 0450 identifies the electromagnetic setup used for the motor’s intended torque and speed range with compatible MSK drive modules.
