Product Description:
The MKD090B-047-GG1-KN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. In automated machinery it supplies controlled rotary motion to axes that demand repeatable speed and position profiles, and its resolver feedback works with drive electronics to close the velocity and position loops.
This model delivers a continuous standstill torque of 12.0 Nm, allowing it to hold load without overheating when stalled under rated current. For short-term stops during power loss, the integrated brake applies 11 Nm of resisting torque, so vertical or rotary tables stay in place until power returns. The square mounting interface is defined by a 140 mm flange, while concentric alignment is maintained by the 110 mm centering diameter; together they match common gearbox and machine frames. Motion feedback is provided by a Resolver (RSF), a passive sensor that survives high temperature and vibration, and drives interpret its analog signals at high resolution to maintain commutation accuracy.
Mechanical layout details support installation flexibility. Cables leave the housing on Side B, and the conductors terminate inside a sealed connection box that simplifies field wiring and shields the resolver leads from electrical noise. The laminated stator stack follows Winding Code 047, establishing the voltage constant and thermal behavior expected by compatible drive controllers. Frame designation 090 indicates the stator outer diameter, and the “B” motor length provides a mid-range inertia for applications that cycle frequently without overshooting. There is a shaft seal that blocks coolant or lubricant from entering the bearing cavity, and the plain shaft design accepts backlash-free clamp couplings.
