Product Description:
The MKD112D-027-KP3-LN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. This electromagnetic actuator converts drive power from a digital inverter into precise rotary motion for positioning and velocity tasks in industrial automation. By combining a permanent-magnet rotor with electronic commutation, the unit supplies closed-loop torque to conveyors, packaging axes, and transfer stations that require accuracy and repeatable duty cycles. Its servo design supports coordinated motion where rapid response and steady control are needed during repeated starts, stops, and speed changes.
A centering diameter of 130 mm aligns the stator in the mounting pilot, while the flange spans 192 mm for coupling to gearboxes or machine frames. At standstill, the electromagnetic system delivers 48.0 Nm of continuous torque, and the integrated spring-applied brake can hold up to 70 Nm when power is removed. The housing has an IP65 rating for resistance to dust and water jets in typical industrial areas. The rotor uses a keyed shaft, a shaft seal is installed, and class F insulation permits winding temperatures up to 155 °C during operation. The motor has size 112, length code D, and winding code 027, and the connections exit on the left side to simplify cable routing in compact machine layouts.
Operational feedback comes from resolver feedback with an integrated encoder, which supports absolute position tracking over more than 4096 revolutions through the drive controller. This sensor combination supports a system accuracy of ±8 angular minutes, which is suitable for closed-loop servo operation without an external scale. A permitted ambient range of 0–40 °C covers most cabinet and machine installations where controlled air circulation is available. The molded power connector allows quick disconnection, and the keyed shaft transfers torque directly to the coupling with positive engagement. The shaft seal helps protect internal components from contaminants, and the holding brake supports a secured parked axis when power is removed.
