Product Description:

The MSK071D-0450-FN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It supplies controlled rotary power to assembly lines, packaging stations, and pick-and-place units that require repeatable positioning. In closed-loop motion systems, it converts drive commands into accurate shaft movement so automated axes can accelerate, stop, and reverse with stable response. That makes it suitable for indexing, transfer, and feed motions where repeatability is more important than simple constant-speed rotation. The size 071 housing and length code D set its installation footprint, while the shaft arrangement supports direct connection to couplings or gear stages for torque transfer.

Its thermal load is removed by liquid cooling, keeping the windings within insulation class 155 during continuous cycling. The electromagnetic circuit follows winding code 0450, which matches the motor's electrical characteristics to the drive current range. Position feedback is delivered by an optical encoder that communicates through the EnDat2.1 digital interface. This sensor produces 2048 signal periods per shaft revolution for smooth speed control, and the IP65 housing helps protect internal components from dust and water jets. Because the cooling circuit removes heat directly from the motor body, continuous duty is better supported in compact machine spaces where free-air cooling would be less effective. The increased concentricity design also helps reduce radial runout at higher speeds.

The feedback connector is rotatable 240°, allowing the cable exit to be positioned with less strain during installation. Cable orientation flexibility is useful when the motor is mounted near guards, slides, or machine frames that restrict routing space. The encoder operates in single-turn mode, so absolute position is retained within one mechanical revolution and suits short-stroke indexing axes. A plain shaft simplifies alignment and works with external holding devices because the motor is supplied without a holding brake. Operation is permitted in ambient temperatures from 0–40 °C, which fits standard machine-room conditions. The plain output end also allows coupling selection to be matched to the machine's torsional requirements.
