Product Description:
The MKD025B-058-KP0-KN servo motor is manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. It delivers controlled rotary motion for positioning, velocity, and torque duties in automated machines such as pick-and-place heads, indexing tables, and light packaging axes. By combining a compact frame with integrated feedback, the unit interfaces directly with Rexroth digital drives and supports deterministic multi-axis sequences in industrial automation. Its compact layout also suits transfer modules and other mechanisms where short motor length helps preserve machine space.
Mechanical mounting starts with the 40 mm centering diameter, which aligns the stator housing concentrically to a machine plate. Field wiring enters on side B, where a sealed connection box groups power, feedback, and protective earth terminals in one location. Under steady-state thermal conditions, the rotor supplies 0.9 Nm of continuous torque, which is suitable for light servo axes that require repeatable force without overheating. Motion is controlled through resolver feedback, whose sine-cosine signals allow the drive controller to track rotor position in real time. This arrangement supports compact installations that use gearheads or belt transmissions without separate external feedback hardware.
At the mounting face, a 54 mm square flange follows IEC dimensions, letting the compact 025-frame motor bolt directly to linear stages and small reducers. Because it ships without a holding brake, any static load must be secured by external clamping or by drive-generated torque while power is available. A shaft with keyway transmits torque through standardized keys, and an internal shaft seal limits oil or coolant ingress along the journal. The electromagnetic circuit uses winding code 058, which sets the motor's electrical characteristics for operation with 60 V class inverters. Motor size 025 with length code B keeps the overall body short, which supports high packing density on multiaxis gantries.
