Product Description:
The MKD112B-048-KP1-LN is a servo motor from Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. In industrial automation, it serves as the electromechanical actuator in coordinated multi-axis systems, translating drive-module current into precise rotary motion for positioning, velocity regulation, or torque control in packaging lines, transfer stations, and machine tools. This role lets the motor respond quickly to changing command values while maintaining stable motion on axes that must start, stop, and reverse repeatedly. The motor uses size 112 stator laminations, length code B, and a left-side power connector as part of its basic mechanical layout.
At standstill, the motor can deliver a continuous torque of 28.0 Nm, so it can sustain substantial load without excess heating. The mounting interface uses a flange that measures 192 mm, allowing direct coupling to standard gearheads and machine plates. A protection rating of IP65 shields the stator and feedback devices against dust and low-pressure water jets, supporting installation on exposed machine axes. Position and speed are reported by resolver feedback, which is integrated into the rear housing for noise-immune analog signaling during closed-loop operation. Insulation class F windings and the 048 winding code set the motor’s thermal and electrical characteristics, while the permissible ambient window of 0-40 °C allows operation inside common factory enclosures.
The electromagnetic brake supplies 22 Nm of holding torque during power-off stops, which helps keep a vertical or indexed axis from drifting when drive power is removed. Accurate axial alignment is supported by a centering diameter of 130 mm, and drive torque is transmitted through a shaft with a keyway that is sealed to limit contaminant entry. The absolute position detector tracks more than 4096 revolutions, and closed-loop accuracy is specified at ±8 angular minutes for repeatable motion on indexing tables or gantry axes. A positive-pressure shaft seal and the left-hand connector orientation complete the motor’s mechanical and electrical interface.
