Product Description:

The MSK071E-0450-NN-M1-BG1-NNAN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It couples to IndraDrive controllers to deliver closed-loop torque and velocity for packaging stations, pick-and-place modules, and general automation axes. This arrangement supports precise positioning and stable speed regulation on axes that start and stop frequently. The encoder is mounted in the M1 position, and its data pair exits with the power leads on the B-side for straightforward routing.

Heat is removed through natural convection, so no external fan or liquid circuit is required. This simplifies cabinet layout and eliminates extra cooling lines. The mechanical structure has reduced run-out, which limits radial deviation at the plain shaft during high-speed cycles and helps protect connected couplings. Feedback is generated by an encoder with a Hiperface digital interface; it transmits position data at 128 signal periods per electrical revolution from an optical scanning head. An electrically released holding brake supplies 23 Nm of static torque to secure vertical loads during power-off or emergency stop conditions.

The sensing element has multi-turn absolute functionality, so the drive retains position after shutdown without external batteries. The motor frame corresponds to size 071 and length code E, matched with winding code 0450 for torque output that fits standard MSK drive ratings. A plain shaft supports backlash-free coupling, and the connector layout keeps wiring organized inside feed-through plates. Environmental sealing to IP65 blocks dust and directed water jets, while Class 155 insulation supports continuous operation in housings that remain within an ambient range of 0 to 40 °C. The finned housing supports heat dissipation during continuous servo operation without additional cooling hardware.
