Product Description:

The MKD025B-058-KG0-KN is a compact servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Within automated assembly lines and pick-and-place equipment, this unit converts drive-controller commands into controlled rotary motion that positions tooling or conveyors with repeatable accuracy. As the active component in a closed-loop axis, it supplies precisely metered torque and speed while fitting into machine layouts where space and wiring access are limited. Its compact format supports use on small handling axes where short cable routes and tight mounting clearances are important. It can be paired with compatible servo controls for indexing, transfer, and light positioning tasks in compact automation stations.

Its mechanical interface uses a 40 mm centering diameter, allowing the flange to seat concentrically on gearboxes or machine plates. The mounting flange measures 54 mm, matching frame size 025, while the housing follows the B length code. Power and feedback conductors enter on side B through a connection box, simplifying right-angle cabinet layouts. The motor delivers a continuous standstill torque of 0.9 Nm through a plain shaft with an integral shaft seal. Because the motor is supplied without a holding brake, external clamping must be provided when power is removed. The housing is sealed to IP65, so installation in spray or dust zones is permitted.

Control accuracy comes from resolver feedback with an integrated encoder that supplies absolute position data exceeding 4096 revolutions. This signal provides a system precision of ±8 angular minutes. The stator uses winding code 058, matched to compatible drives while remaining within the motor's F insulation class thermal limits. Continuous operation is permitted at ambient temperatures from 0–40 °C, and absolute multi-turn detection maintains position during power cycles. These feedback and thermal characteristics support stable motion control during repeated starts, stops, and position changes.
