Product Description:
The MSK071D-0450-NN-S2-UG2-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts output from a compatible drive controller into precise rotary motion for indexing tables, packaging actuators, and gantry axes that require repeatable torque and position control. The motor is intended for direct integration into automated machinery, so its compact format supports installation where separate protective covers are not desirable. Its servo design also supports accurate response during starts, stops, and speed changes in cyclic motion applications.
The motor housing has an IP65 protection rating, which helps block dust ingress and low-pressure water jets from reaching internal components. Cooling is provided by natural convection, so the installation should leave clear airflow around the housing fins to remove heat during operation. Within an ambient range of 0 to 40 °C, the 0450 winding can deliver rated performance, and the increased concentricity design helps keep shaft runout low. An electrically released holding brake provides 30 Nm of static torque when power is removed, and position data is transmitted through the EnDat 2.1 interface for closed-loop control.
Feedback is generated by an optical single-turn encoder with 2048 signal periods, giving the drive fine position information for smooth velocity regulation. The encoder connector can rotate through 240 degrees, which helps cable routing in tight machine spaces and reduces strain at the connection point. Mechanical power is transmitted through a plain shaft, while the 071 frame with D-length stack balances torque output and motor mass for medium-duty axes. The insulated windings are rated to thermal class 155, allowing sustained current without premature varnish aging.
