Product Description:
The MSK071C-0300-NN-S2-UG0-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is applied in industrial automation systems where closed-loop velocity and position control are critical. By directly coupling its plain shaft to mechanical loads, the motor converts regulated drive current into precise torque for packaging lines, handling modules, and assembly axes, while the frame remains compact enough for cabinet or machine-bed installation.
The motor is cooled by natural convection, so heat leaves the housing without forced airflow, which simplifies enclosure design and reduces maintenance. Its protection rating of IP65 seals the stator against dust and low-pressure water jets encountered on production floors. With a frame code of 071 and length designation C, the unit delivers the output expected from medium-sized axes while maintaining manageable mass and inertia. Internal windings follow code 0300, matching drive inverters that supply the required voltage constant and resistance profile. Thermally, Class 155 insulation withstands recurring temperature rise during continuous duty. Rotor position feedback is generated at 2048 signal periods per revolution, giving high digital resolution for smooth interpolation within the drive controller.
Signal exchange with the controller uses the EnDat2.1 interface, which carries position data and diagnostics over a bidirectional serial link. Feedback is produced by an optical scanning system, ensuring low jitter and long-term stability compared to magnetic encoders. The connector can be rotated through 240°, letting the cable exit be oriented to reduce strain inside tight cabinets. The single-turn architecture tracks absolute position within one mechanical turn, which removes the need for external homing routines in many applications. Operation is specified for ambient temperatures from 0 to 40 °C, so no additional conditioning is needed in standard plant environments. The motor ships without a holding brake, so static holding must be provided by external clamping or drive-applied torque when required.
