Product Description:
The MKD090B-047-GP1-KN is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MKD Synchronous Motors series. Within automated machinery it converts drive current into regulated rotary motion so axes can be positioned with tight velocity and torque control. The motor’s dimensional code 090 and length class B place it in the medium power segment favored in packaging lines, material-handling stations, and light machining centers.
Its mechanical interface is defined by a 140 mm flange size and a 110 mm centering diameter, giving a rigid mounting surface while ensuring coaxial alignment with gearboxes or belt pulleys. A keyed steel shaft—listed as Shaft with keyway—transmits the rated torque, which reaches 12.0 Nm continuous at standstill without excessive heating when the Resolver feedback (RSF) maintains rotor position. The resolver supplies incremental and absolute angle data, so the drive can apply field-oriented current even during acceleration. Position detection is relative, matching applications where homing routines are executed at start-up. Thermal behavior and impedance are tied to winding code 047, and the unit’s sealed front bearing includes a shaft seal to limit lubricant escape and particle ingress. The motor ships with a holding brake that engages whenever power is removed.
Electrical terminations exit on the Side B connections, and a compact connection box termination houses both power and sensor leads to simplify cabinet wiring. Inside the stator, the 047 winding code balances resistance with inductance so the drive can supply peak current without overshoot. A permanent-magnet brake is fitted; its 11 Nm holding brake torque prevents back-driving during power loss and allows maintenance positioning. Together, motor size 090, length class B, and the integrated shaft seal complete a package that fits through the 140 mm square mounting face while still providing resolver-based relative position reporting and 12.0 Nm of continuous torque.
