Product Description:

The MSK071E-0300-NN-S3-AP0-NNAN is a synchronous servomotor manufactured by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. In automated production lines, it couples with IndraDrive amplifiers to deliver closed-loop speed and position control for indexing tables, forming presses, and multi-axis gantries. The motor converts modulated three-phase currents into smooth torque, allowing machinery to achieve repeatable trajectories without the mechanical backlash associated with gear trains.

Its thermal management relies on natural convection, so heat dissipates through the stator housing without external blowers or liquid circuits. Position data are exchanged through the Hiperface interface, and the integrated encoder resolves the rotor angle into 16 signal periods per electrical revolution; this capacitive sensing method resists magnetic interference while the single-turn architecture tracks motion over one mechanical turn. A reduced runout design minimizes shaft axial deviation, which is important when coupling the 071 frame to precision gearheads. The mechanical envelope corresponds to motor length code E, the electrical characteristics follow winding code 0300 for compatibility with medium-voltage inverters, power conductors terminate on the A-side connector, and the shaft is machined with a keyway to provide slip-free torque transfer under intermittent load peaks.

The motor has an IP65 enclosure, which blocks dust ingress and low-pressure water jets in wash-down zones. Thermal insulation class 155 permits winding temperatures up to 155 °C before aging accelerates, aligning with an ambient operating window of 0–40 °C. Because the unit is supplied without a holding brake, an external locking mechanism is required when the shaft must remain stationary after power removal.
