Product Description:
Bosch Rexroth Indramat builds the MSK071D-0200-NN-M2-UG1-RNNN for the MSK IndraDyn S Synchronous Motors series. The unit is a brushless AC servomotor intended for closed-loop motion axes in automated assembly cells, material-handling gantries, and packaging lines where high dynamic positioning accuracy is required. By coupling with an IndraDrive inverter, it converts commanded currents into proportional torque, allowing the attached load to follow programmed velocity and position profiles with minimal deviation. The brushless design also avoids commutator wear, which supports low-maintenance operation in continuously cycling equipment.
Thermal management relies on natural convection, so the housing surface dissipates heat without external fans or liquid circuits. A protection rating of IP65 blocks dust ingress and water jets, enabling direct mounting outside sealed cabinets when the surrounding machine area permits. Position feedback is handled by an optical encoder that offers 2048 signal periods per revolution, and the EnDat2.1 interface passes that data to the drive for closed-loop control. Its absolute multiturn design preserves position information across power cycles, which helps the control system retain shaft reference after shutdown. The encoder connector is rotatable through 240°, which simplifies cable routing in tight machines. An increased-concentricity version reduces radial runout and supports smooth rotation at higher shaft speeds.
Mechanical holding force is supplied by an electrically released brake rated at 23 Nm, allowing vertical axes to remain fixed during power loss or a commanded stop. The drive end uses a plain shaft, so torque is transferred through friction hubs or shrink discs instead of keys. Continuous operation is permitted at ambient temperatures of 0 to 40 °C, and the windings use insulation class 155 to tolerate elevated copper temperatures. Motor size 071, length D, and winding code 0200 identify the electromagnetic and dimensional arrangement expected by the matching drive. This layout supports stable servo response in applications that need compact motor dimensions and precise axis control.
