Product Description:

The MKD090B-047-GP0-KN is a three-phase servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It functions as the rotary actuator in closed-loop drive systems, receiving current from an Indramat drive controller and delivering constant torque to automated machinery such as gantry axes, packaging stations, and handling modules. When paired with a compatible controller, it supports accurate speed and position control during repeated motion cycles.

This model has a centering diameter of 110 mm, allowing precise alignment against the mating pilot on a 140 mm square mounting interface. Under continuous stall conditions, it can hold 12.0 Nm of torque without overheating, so static loads remain stable during dwell periods. Rotor position is reported through resolver feedback (RSF), giving analog sine-cosine signals for fine commutation even during rapid speed reversals. Power and feedback conductors exit on the rear housing face designated as Side B, simplifying cable routing in cabinets where the front face is embedded. A square flange measuring 140 mm on each side mates to ISO motor adapters and keeps the shaft axis concentric with geared reducers or timing pulleys.

Terminals are grouped inside a sealed connection box, so field wiring can be completed without opening the stator frame. The output end uses a shaft with a keyway, enabling positive mechanical locking to couplings that transfer intermittent or bidirectional torque peaks. A shaft seal is fitted to block coolant spray and airborne dust from entering the bearing set. Relative commutation is supported because the feedback system provides relative position data referenced from an index on power-up. The windings use code 047, matching the electrical resistance and inductance expected by MKD drives for this 090 frame. Length code B keeps the active stack short, reducing rotor inertia so axes accelerate quickly when commanded by CNC or PLC profiles.
