Product Description:

Bosch Rexroth Indramat produces the MKD112B-048-GP2-AN, a servo motor in the MKD Synchronous Motors series used for closed-loop motion axes in automated machinery. As a servo element, it converts regulated electrical output from a drive controller into precise mechanical torque and speed, allowing positioning, indexing, and coordinated moves on packaging lines, material handling stations, and CNC tables. Its electromagnetic design supports high cycle rates while maintaining feedback alignment through its integrated resolver, making the unit suitable for systems that demand repeatable motion under continuous duty.

The motor delivers a continuous standstill torque of 28.0 Nm, so it can hold loads without thermal drift when axis motion is blocked. A flange face measuring 192 mm and a centering diameter of 130 mm align the housing with gearboxes or machine frames, supporting concentric power transfer and a simpler mechanical layout. The motor has an IP65 protection category, which helps seal the stator against dust ingress and low-pressure water streams. Position feedback relies on resolver feedback, which provides analog sine-cosine signals with coarse resolution and high shock resistance. Mechanical coupling is through a shaft with keyway, allowing torque to pass into pulleys or couplings while preventing relative slip during dynamic reversal.

The MKD112B motor uses winding code 048, linking its copper content and impedance to the matching drive parameters such as nominal current. Operating accuracy across repeated cycles is maintained within ±8 angular minutes, which suits medium-precision transport and positioning tasks without external encoders. Reliable service is supported at ambient temperatures from 0 to 40 °C, and an installed shaft seal retains lubricant while blocking coolants or dust from migrating along the output shaft during extended production shifts.
