Product Description:
The MKD025A-144-KP0-KS servo motor is built by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. This compact motor is intended for closed-loop positioning tasks in industrial automation, where it converts drive commands into accurate rotary motion for small actuators, index tables, or tooling heads. When paired with a compatible drive, it supports precise position and speed control on small axes that require stable feedback and repeatable motion. Its compact format also suits assemblies where installation space is limited and moving mass must remain low.
At stall, the motor delivers a continuous torque of 0.4 Nm, providing steady output for light mechanical loads without overheating. A centering diameter of 40 mm and a flange size of 54 mm form the mounting interface, helping the motor seat accurately against machine plates or gear units. This mounting arrangement helps maintain shaft alignment and can reduce unwanted stress on couplings during installation. Motion feedback is provided by resolver feedback, which allows the control to track rotor position over multiple revolutions. The housing is rated IP65, and F-class insulation supports dependable operation in enclosed industrial equipment. The unit is supplied without a holding brake, so holding force at standstill must be provided by drive torque or an external clamp.
The electrical and feedback leads exit on side B through a sealed connection box, which can help keep cable routing orderly inside compact machine frames. That cable exit location can also keep the harness away from adjacent moving parts in tightly packed equipment. System repeatability is specified at ±8 angular minutes, supporting accurate indexing and consistent return to position during repeated cycles. The motor maintains its stated performance in ambient temperatures from 0–40 °C without requiring additional cooling hardware. A shaft with keyway provides positive torque transmission to couplings or pulleys, while the installed shaft seal helps protect internal components from dust and moisture during normal operation. This shaft style is useful where the driven element must resist slip during frequent starts and stops.
