Product Description:

The MKD090B-047-KP1-KS is a servo motor produced by Bosch Rexroth Indramat for motion tasks in the MKD Synchronous Motors series. It is intended to drive axes that need repeatable speed and position control in automated machinery, packaging stations, and material-handling modules. By combining permanent-magnet technology with integrated feedback, the unit converts electrical energy from the associated drive controller into controlled mechanical rotation that can be synchronized with a machine control system. That makes it suitable for coordinated servo axes that must start, stop, reverse, and hold position in step with other machine functions.

This motor sits on a 110 mm centering pilot and fits to machines through a DIN flange that measures 140 mm across, so alignment and torque transfer remain consistent at the mounting face. Power and feedback conductors exit on side B through a sealed connection box, which helps route cables in compact machine layouts while keeping the connection point enclosed. When the rotor is energized but held stationary, the shaft delivers a continuous torque of 12.0 Nm, which is the thermal limit for static holding or low-speed indexing. Position information is generated by resolver feedback integrated behind the stator, and its analog signals support accurate commutation even in electrically noisy environments. The winding code 047, size 090, and length B describe the electrical and mechanical configuration used for this motor variant.

An electromechanical holding brake rated at 11 Nm engages automatically during power-off states to help prevent axis drift on vertical loads. Torque is transferred through a balanced keyway shaft, and an internal shaft seal helps keep oil or coolant away from the front bearing during washdown cycles. The feedback system provides multiturn absolute feedback for more than 4096 revolutions, so the controller can recover rotor angle after an outage without a homing routine and resume position-aware operation.
