MSK071D-0450-NN-M1-UP1-NSNN
MSK IndraDyn S Synchronous Motors
The MSK071D-0450-NN-M1-UP1-NSNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In industrial automation systems, the unit converts electrical energy into controlled rotary motion, enabling precise positioning and speed regulation on packaging, handling, and machining axes. Its name code references the 071 frame size and D-length stack, allowing integrators to match the motor to mechanical loads and cabinet space constraints.
During operation the motor dissipates heat through Natural convection, eliminating the need for auxiliary fans and simplifying enclosure ventilation planning. The integrated encoder uses the Hiperface digital interface, providing high-speed feedback to Rexroth drive controllers over a pair of data lines. Its optical scanning method resolves rotor position into 128 signal periods, and the underlying Optical technology maintains repeatable accuracy by detecting fine gratings rather than relying on magnetic elements. Size 071 housing and the D-length magnetic stack balance torque density and inertia for mid-range axes, while winding code 0450 defines the electrical resistance and inductance values required by the power stage.
The electrically-released holding brake produces 23 Nm of static torque, allowing the axis to stay locked during power-off or emergency stop conditions. Position feedback retains absolute counts over multiple revolutions because the encoder is of the Multiturn Absolute type, removing the need for homing after shutdowns. To simplify cable routing, the feedback connector is Rotatable, 240°, enabling lateral or vertical exit without stressing conductors. Mechanical power is transmitted through a Shaft with keyway, a profile that aligns the rotor to standard couplings while preventing slip under cyclic loads. The motor’s construction follows the Standard and Explosion Protection design variant, extending its use to classified hazardous areas without modification.
