Product Description:
The MKD090B-047-KG0-KN is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. It serves as the rotary drive element in automated production lines, transferring commanded torque directly to machine mechanics while providing position data for the drive controller. Used with digital inverters, the motor maintains synchronous operation between the electromagnetic field in its stator and the commanded frequency, enabling repeatable motion sequences in packaging, printing and material-handling cells.
Mechanical integration is based on a 140 mm square flange paired with a centering diameter of 110 mm to align the housing on gearheads or frames. The power, resolver and protective-earth leads exit on Side B through a sealed connection box, allowing cable routing along the machine’s rear face. Under continuous stall conditions the rotor withstands a load of 12.0 Nm without exceeding thermal limits. Size code 090 and length code B define a medium-diameter stator stack that balances torque density with compact overall length. A shaft seal is installed so lubricants, coolants or airborne particles do not enter the bearing chamber.
Feedback and commutation are handled by a resolver feedback unit integrated into the rear housing. This sensor supports Absolute (>4096 revs) tracking, so the drive captures multi-turn position immediately after power-up without external homing. Stator winding code 047 sets the electrical resistance and inductance pairings expected by Rexroth drive modules, ensuring accurate current control during acceleration and regenerative braking. A plain shaft allows direct clamp coupling, minimizing backlash in precision slides or indexing tables while the sealed housing protects the windings during continuous duty cycles in ambient shop temperatures.
