Product Description:

Bosch Rexroth Indramat builds the MKD025B-144-KG1-KS servo motor for use in the MKD Synchronous Motors series. The unit converts command currents from a digital drive into mechanical rotation for light-duty positioning axes, pick-and-place heads, and small tooling spindles in automated cells. Its compact frame and integrated feedback allow the motor to deliver repeatable motion while occupying minimal cabinet or machine space. It serves as an electromechanical actuator that closes the control loop between the drive controller and the load, providing precise torque and speed regulation for modern production lines.

The mechanical interface starts with a centering pilot of 40 mm that guides the housing into the mating flange and keeps radial runout within tolerance. A flange size of 54 mm sets the bolt circle and matches micromachinery mounting grids. During static operation, the motor can deliver a continuous standstill torque of 0.9 Nm, allowing direct drive of light linear tables without gear reduction. Position repeatability is supported by a system precision of ±8 angular minutes, and the sealed construction has an IP65 rating that helps keep dust and water jets away from the internal windings.

Electrical characteristics are tuned by winding code 144, which pairs the stator impedance with low-voltage drives for high acceleration. Thermal endurance comes from the Class F insulation system and an operating temperature range of 0–40 °C. Motion is verified through resolver feedback that supplies position data for more than 4096 revolutions, and the plain shaft is protected by a shaft seal to limit lubricant egress. Connections exit on side B through a compact connection box, and the size 025, length B housing keeps mass low. A spring-applied holding brake generates 1 Nm to secure vertical loads when power is removed.
