Product Description:

The MKD025B-144-KP1-UN servo motor is manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. Supplied for use with electronic drive systems, this compact rotary actuator works with a digital controller to deliver precise speed and position regulation on pick-and-place stations, small gantries, and packaging equipment. By synchronizing stator winding current with the rotor magnets, the motor provides repeatable torque and rapid response that improve cycle consistency and reduce the need for complex mechanical gearing. This type of response is useful in applications that require short positioning moves and frequent start-stop cycles.

The motor uses a 40 mm centering diameter to align the housing on the mating machine surface, and it has a 54 mm square flange that accepts standard bolt patterns for size-025 frames. The stator winding identified as code 144 works with the B-length housing to produce a continuous standstill torque of 0.9 Nm, which suits lightweight index tables or belt pulleys without extra reduction. Position and velocity feedback are supplied by resolver feedback integrated behind the shaft, giving analog sine-cosine signals to the controller and helping the motor operate reliably in electrically noisy areas. Power and encoder connectors can be rotated through 270°, which gives more flexibility when routing cables around guards, frames, or nearby axes.

The integrated brake delivers 1 Nm of holding torque, which helps keep vertical or inertial loads in place when supply power is removed. A shaft with a keyway provides positive mechanical coupling to gears or pulleys, while the shaft seal helps limit lubricant migration and the entry of fine dust into the internal bearings. For multi-turn homing, the motor offers absolute position detection of more than 4096 revolutions, so restart sequences can resume without an external reference move. This helps the axis return to operation with position information already available to the control system.
