Product Description:

Bosch Rexroth Indramat manufactures the MSK071E-0300-NN-M2-UG0-RSNN servomotor for the MSK IndraDyn S Synchronous Motors series. This IndraDyn S synchronous servomotor converts drive current into precise rotary motion for positioning axes, pick-and-place heads, and other automated machine functions that require fast response and repeatable accuracy. Its mechanical design meets requirements for increased concentricity and certified explosion protection, making the unit suitable for process lines where low shaft runout and compliance with hazardous-zone standards are necessary.

The motor is cooled exclusively by natural convection, so heat is removed through the housing fins without auxiliary fans or liquid circuits. A sealing system rated at IP65 prevents dust ingress and protects the stator against low-pressure water jets, allowing cabinet-free mounting. Safe operation is specified for ambient air from 0 to 40 °C, ensuring full torque delivery in typical plant environments. Position data is transferred through an EnDat2.1 interface, and the integrated optical encoder resolves 2048 signal periods per revolution. The connector can be rotated 240°, which eases cable routing in confined cabinets. The motor uses winding code 0300 and is supplied without a holding brake, which helps reduce inertia.

Frame sizing follows code 071, which corresponds to the flange and stator diameter used with standardized gearheads. Within that frame, motor length E indicates a longer active core for higher continuous torque. The output is a plain shaft, which mates directly with clamp couplings or keyless hubs to reduce backlash. The windings use insulation class 155, allowing a maximum winding temperature of 155 °C during cyclic duty. Absolute feedback spans 4096 turns because the encoder is a multi-turn absolute encoder, eliminating the need for homing routines after shutdowns.
