Product Description:

The MKD112D-027-KG3-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. In motion-control installations, it receives current commands from a drive controller and converts them into regulated torque and speed for indexing, acceleration, and controlled holding functions. This operating principle lets automated machinery position axes with repeatable response during start-stop cycles and speed changes. Because current is controlled continuously by the paired drive, the motor can follow changing command values with smooth and accurate rotary output. It is intended for closed-loop applications where dependable axis motion is required throughout normal machine operation.

The motor delivers a continuous standstill torque of 48.0 Nm, so it can support sizable static loads without overheating. A square mounting interface with a 192 mm flange size fits standard machine plates, and the 130 mm centering diameter keeps the housing aligned with the driven shaft. The mounting geometry helps preserve concentric alignment between the motor and the connected load. During power loss, a spring-applied brake supplies 70 Nm of holding torque to keep the load stationary until motion is re-enabled. Position data are provided through absolute feedback (>4096 revolutions), allowing the drive to recover rotor position after a restart without requiring an immediate reference move.

Power and feedback connections are routed on Side B, which keeps cabling away from the driven face and can simplify routing in compact machine layouts. Closed-loop operation uses resolver feedback with integrated encoder, supplying stable signals in electrically noisy environments. The motor uses a plain shaft for hub or clamp-style couplings, while a shaft seal helps retain bearing lubricant and block contaminants. It is built in frame size 112 with motor length D and winding code 027, and it uses an output connector plus internal sealing to limit dust and coolant entry. The connector arrangement supports cleaner cable management around couplings, gearboxes, and other adjacent machine components.
