Product Description:
The MKD112B-048-KP2-AN is a servo motor from Bosch Rexroth Indramat’s MKD Synchronous Motors series. As a rotary actuator, it converts electrical power from an IndraDrive amplifier into controlled mechanical torque for automated machinery axes. This model suits medium-inertia loads such as indexing tables, pick-and-place gantries, and conveyor modules, where precise, repeatable motion is required without additional gear reduction. Its B-length stator and size-112 frame support installation in compact machines with limited mounting depth.
The motor delivers a continuous standstill torque of 28.0 Nm, allowing holding or low-speed duties without overheating when forced ventilation is available. A centering shoulder diameter of 130 mm aligns the housing precisely against the machine interface, while the square flange spans 192 mm to match standardized mounting patterns. The enclosure provides IP65 protection, keeping internal windings free from dust and low-pressure water jets. The stator windings use class F insulation, so conductor temperature can reach 155 °C before thermal limits are reached. Electrical power and feedback leave the housing toward Side A through an output connector that simplifies parallel axis wiring.
The MKD112B operates in ambient air between 0–40 °C, so cabinet airflow must maintain inlet temperature within this range. Position feedback uses a resolver-based encoder chain that achieves system accuracy of ±8 angular minutes and retains an absolute count for more than 4096 revolutions, eliminating homing after power cycling. Mechanical power is transmitted through a shaft with keyway, and a shaft seal is fitted to prevent lubricant ingress along the journal. The B-length lamination stack and winding code 048 combine to give nominal voltage and speed values compatible with mid-range IndraDrive controllers.
