Product Description:

The MKD025B-144-GP0-UN belongs to the MKD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a brushless servo motor that converts drive commands into precise rotary motion for indexing tables, pick-and-place axes, and small spindle drives in automated equipment. By delivering commanded torque accurately and responding quickly to feedback, the unit supports repeatable positioning tasks throughout an industrial automation cell. Its compact format also suits installations where axis spacing is limited and fast response is important.

This motor provides a continuous standstill torque of 0.9 Nm, allowing it to maintain load position without overheating while the machine is idle. The mounting interface uses a 54 mm square flange and a centering diameter of 40 mm, which simplifies alignment with compact gearboxes or direct-drive fixtures. A keyed mechanical interface is implemented through a shaft with keyway, preventing slip under cyclic torque. Power and encoder connectors can be swiveled because the connection block is turnable within 270°, which eases cable routing in cramped panels. The connectors separate motor power from signal lines, reducing noise coupling and simplifying service access. This arrangement also helps when the motor is mounted close to guarding or neighboring machine components.

Electromagnetic behavior follows winding code 144, matching the drive’s voltage and current profile to the motor windings. The motor uses frame size 025 with length code B, so the stator stack remains short for low-inertia moves. Rotor position is measured by Resolver feedback (RSF), which supplies analog sine-cosine signals for high-resolution relative position detection. The design omits a holding brake, so external locking or drive torque must secure vertical loads when power is off. An integral shaft seal helps block lubricant or coolant ingress along the output journal. This feedback and sealing arrangement supports steady operation in compact closed-loop motion systems.
