Product Description:

The MKD025A-144-GG0-KS servo motor is manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. Designed for compact axes in packaging, electronics, and handling equipment, the unit converts drive current into rotational motion so a connected drive can control speed and position in closed-loop automation. Electrical and sensor interfaces exit on Side B, which helps keep cables away from the driven shaft in tight assemblies.

Its mounting interface uses a centering diameter of 40 mm and a square flange that measures 54 mm, allowing the motor to align with small gearheads or machine plates. At standstill, the electromagnetic circuit can deliver 0.4 Nm of continuous torque, which is suitable for light holding loads when rated current is applied. The windings use insulation class F, which permits winding temperatures up to 155 °C during intermittent duty. A molded connection box houses the power and feedback terminals, and the housing meets IP65 to help prevent dust ingress and low-pressure water jets from reaching internal components. System precision is rated at ±8 arcminutes, and the plain shaft transmits torque directly to a coupling or pulley without keys. The motor is supplied without a holding brake, which helps reduce weight and moment of inertia.

Rotor angle is reported through resolver feedback, so the drive receives relative position information during operation. Because the feedback system provides only relative position detection, absolute referencing must be carried out by the machine controller after power-up. A positive-fit shaft seal is fitted at the flange to limit oil or coolant migration along the shaft journal. Operation is permitted from 0 to 40 °C, which matches typical cabinet climates on factory floors. The motor has frame size 025 and motor length A, and its nominal characteristics apply when the connection box is used with the manufacturer-specified cable gauges.
