Product Description:

The MSK071D-0450-NN-M2-UP1-RNNN is a synchronous servomotor built by Bosch Rexroth Indramat and delivered as a member of the MSK IndraDyn S Synchronous Motors series. In automated machinery, it converts precision drive commands from an IndraDrive servo amplifier into regulated rotary motion for positioning tasks, packaging lines, and material-handling axes. The encoder data stream is transferred through the EnDat2.1 digital interface and exits the motor on a connector that can be rotated 240°, simplifying cable routing in tight machine spaces.

Heat is removed through natural convection, so the housing surface alone disperses losses without external fans or liquid circuits. The electrically released holding brake supplies 23 Nm of static torque, allowing the axis to stay fixed during power-off while releasing automatically when current is applied. Position feedback is generated by an optical encoder that supplies 2048 signal periods per revolution, giving the drive high resolution for velocity and position loops. The motor body carries a protection rating of IP65, sealing it against dust ingress and low-pressure water jets in typical plant environments. Reliable service is specified for ambient temperatures from 0 to 40 °C, and the windings use insulation class 155 to tolerate internal temperatures associated with continuous cyclic duty.

Multiturn absolute functionality keeps track of shaft revolutions when power is interrupted, and the optical scanning method preserves accuracy over the stated lifetime. The internal winding configuration identified by code 0450 is matched to the D length variant of the 071 size frame, giving a balance between torque density and overall inertia. Mechanically, the increased concentricity design minimizes runout at the keyed shaft, and the keyway transmits torque to couplings without slip.
