Product Description:
The MKD090B-058-K01-KN is a servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. Designed for closed-loop drive systems, the unit converts electrical power into controlled rotary motion for positioning or velocity tasks on automated machinery. Its electromechanical design follows a modular frame concept, allowing it to mount directly to gearheads or machine frames while interfacing with Indramat digital drives. Because the motor is intended for servo use, the drive can regulate torque output precisely during acceleration, steady running, and deceleration.
Its square flange measures 140 mm and mates with a centering pilot of 110 mm, so the shaft seats concentrically and vibration is minimized. The centering diameter matches ISO mounting patterns, and the mechanical sealing lip around the pilot helps keep grease and particles away from the bearing seat. Power and feedback conductors exit on side B through a sealed connection box, which simplifies wiring and shields terminals from coolant splash. The winding identified by code 058 is intended for use with compatible Indramat drives, enabling the motor to deliver a continuous standstill torque of 12.0 Nm without exceeding its thermal limits. Size 090 and length class B give the motor moderate rotor inertia, which suits indexers and feed axes that need responsive motion and stable load control.
The built-in holding mechanism applies 11 Nm of static torque, allowing vertical loads to remain stationary when power is removed. Motion feedback is supplied by a resolver feedback device integrated with the rotor, and the associated electronics provide absolute position detection for more than 4096 revolutions, eliminating homing cycles after startup. This feedback arrangement lets the control system recover position information after an interruption and return the axis to operation with less delay. It is useful on packaging, printing, and material-handling machines where repeatable positioning and stable rest holding are both required.
