Product Description:

The MSK071D-0450-NN-M1-UG2-NSNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive current into controlled rotary motion for positioning and variable-speed tasks in industrial automation. The D-length frame accommodates the 0450 winding while keeping the motor body suited to axes that need substantial output without an oversized installation envelope. In automated handling, packaging, and transfer systems, this layout supports repeatable motion when paired with a compatible drive and feedback channel.

Thermal management relies on natural convection, so heat leaves the housing through surface radiation and normal ambient air movement rather than through fans or liquid jackets. An electrically released holding brake supplies 30 Nm of static torque to secure vertical or suspended axes during power loss, which helps prevent unintended movement at standstill. The feedback connection is rotatable 240°, making cable routing easier in tight machine layouts or when the connector must face a specific direction after mounting. Position data is transmitted through the Hiperface interface, and the encoder provides 128 signal periods per mechanical revolution for smooth closed-loop motion.

An optical scanning system with a multiturn absolute encoder can report shaft angle and multiple revolutions without requiring battery backup for retained position data. Motor size 071 balances torque density and rotor inertia for medium-power axes that need responsive acceleration and stable control. The output uses a plain shaft, which supports direct coupling to pulleys, pinion assemblies, or compatible gear units. A standard or explosion-protected design option is available for applications in hazardous areas when the required certification is included. The FN cooling constraint influences continuous output and installation conditions.
