Product Description:

The MKD112D-027-KP0-LN is a servo motor built by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a rotary actuator, it converts electrical energy from a drive into controlled torque and speed for positioning tasks in automated machinery. Its role in an axis assembly is to deliver rapid, repeatable motion while sending position data back to the controller through integrated feedback devices. This makes the motor suitable for applications that need stable speed control, accurate stopping, and consistent response during repeated motion cycles.

A centering diameter of 130 mm aligns the housing on the machine interface, and a 192 mm flange helps transmit reaction forces into the mounting surface. The shaft uses a keyway and a shaft seal, which helps keep oil spray away from the bearings during operation. Rated standstill torque is 48.0 Nm, allowing the axis to hold substantial loads continuously without overheating. The motor has an IP65 enclosure rating that keeps out dust and low-pressure water jets, and it uses insulation class F winding materials. Motion feedback uses resolver feedback with integrated encoder, and the closed-loop accuracy is ±8 angular minutes. Power and signal cabling exit on the left side through a dedicated power connector, which can simplify cable routing in compact machine layouts.

The winding code 027 identifies the electrical values used by the matching drive. The frame size is 112, and motor length D provides a larger active package within this series. Position information is retained as absolute feedback over more than 4096 revolutions, which can reduce the need for homing after a power loss. The permitted ambient operating temperature is 0–40 °C. Because the motor is supplied without a holding brake, a vertical axis must rely on a mechanical lock or drive torque when power is removed.
