Product Description:
The MKD025B-144-KP0-KN-SA001 is manufactured by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. It is a compact servo motor used in industrial automation where precise rotary motion is required for feeders, small actuators, and light pick-and-place stations. Within these systems, the motor forms part of a closed-loop drive chain that converts drive-controller current into repeatable shaft position and controlled speed. Its compact format makes it suitable for axes where installation space is limited and low moving mass is important for responsive motion.
The mechanical interface includes a centering diameter of 40 mm and a flange measuring 54 mm, allowing direct mounting to low-profile gearheads or machinery frames. Electrical terminations are routed on Side B through a sealed connection box, which helps keep cable routing orderly in tight enclosures. Under continuous stall conditions, the motor develops 0.9 Nm of torque, which suits fine indexing and other light-duty positioning tasks. The motor uses winding code 144, which corresponds to its coil impedance and thermal behavior in this frame size. Its B-length housing and 025 frame size help keep mass and inertia low so the axis can accelerate quickly and respond smoothly to changing commands.
The unit is supplied without a holding brake, so position retention must be provided by drive torque or an external clamp when the axis is stopped. Rotor angle is monitored by a resolver feedback system, and its integrated electronics provide an absolute position count exceeding 4096 revolutions for multi-turn reference recovery after power cycles. Power is transmitted through a shaft with keyway, and a shaft seal helps block lubricant migration into the motor interior. The sealed shaft area and the gaskets around the connection box support reliable operation in enclosed machine assemblies where stable feedback and secure power transmission are both required.
