Product Description:

The MSK070D-0450-NN-S1-BG0-NNAN is a synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. In automated production lines, the motor supplies tightly regulated torque and velocity to positioning axes, enabling repeatable motion cycles for material handling, assembly, and inspection stations. Its reduced runout design minimizes radial deviation between the shaft and stator, improving feedback accuracy and extending bearing life during high-duty operation. This makes the motor suitable for multi-axis gantries and electronic packaging lines where stable motion and precise positioning are required.

Thermal management is provided by natural convection, so heat is dissipated through the housing surface without auxiliary fans. The integrated encoder uses the Hiperface interface, and its scanning head detects 128 signal periods per revolution by an optical method, delivering fine position data to the drive controller. Because the encoder is single-turn, it reports absolute angular position within one mechanical revolution, eliminating the need for battery-backed multi-turn electronics when only one turn of absolute data is needed. The plain shaft layout mates directly to keyed or clamped couplings, and winding code 0450 establishes the electrical characteristics required by a compatible IndraDrive inverter.

The motor is supplied without a holding brake, so external load holding or drive torque must secure the axis when power is removed. Its length class D provides a higher stack height than shorter variants, increasing continuous torque while preserving the 70 mm frame. That frame is designated size 070, allowing the motor to fit standardized MSK mounting flanges. Power enters on the B-side of the housing, which helps keep the feedback side clear for signal cabling and reduces connector congestion.
