Product Description:
The MSK075D-0200-NN-S2-UG1-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In motion-control systems, it converts drive output into precise torque and speed, enabling pick-and-place, printing, and packaging axes to reach commanded positions within milliseconds. A 075 frame diameter combined with the D length code provides a balanced ratio of torque to inertia for responsive axis motion, and the plain shaft allows direct coupling. The mechanical section uses an increased concentricity design so runout remains low during high-speed rotation and helps protect attached mechanics from vibration.
Heat generated in the windings is removed by natural convection, so the motor can be mounted without external fans when adequate ambient airflow is available. Position feedback exits through a rotatable 240° encoder connector, and the sensing element communicates through EnDat2.1. Because the feedback disk carries 2048 signal periods per revolution, the connected drive can interpolate fine increments for tight velocity control. A spring-loaded, electrically released holding brake supplies 23 Nm of static torque to secure loads when power is removed. The aluminum housing meets IP65, preventing dust ingress and withstanding low-pressure water jets during routine washdown procedures. Winding code 0200 sets the coil resistance and inductance values used by the drive for current limiting.
The feedback assembly relies on optical scanning and a single-turn code track, which supplies absolute position for one mechanical revolution without battery support. Safe operation is maintained across an ambient temperature range of 0-40°C. The Class 155 insulation system tolerates the internal copper temperatures reached during acceleration. The motor’s rotor inertia is sized for medium-weight indexing tables, letting current regulators settle quickly after each move. This predictable dynamic behavior supports high throughput without exceeding thermal limits.
