Product Description:

The MKD112D-027-KP3-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It is intended for drive axes that require rapid speed changes and repeatable positioning, such as gantry heads, tool changers, and packaging stations. Its D-length stator increases copper volume over shorter variants, so more thermal mass is available for sustained duty without altering the mechanical envelope. As part of a closed-loop motion chain, the motor receives three-phase current from a digital drive and converts it into controlled rotary motion for industrial automation tasks.

Mechanical output is supported by a continuous standstill torque of 48.0 Nm, allowing the rotor to resist load forces while stationary. For power-off safety, the integrated brake supplies a holding capacity of 70 Nm, preventing back-driving on vertical or indexing axes. The square mounting interface measures 192 mm across, and a pilot of 130 mm centers the housing to limit radial runout when the motor is bolted to a gearbox or frame. Electrical characteristics are tied to winding code 027, which establishes the voltage constant and rated current that the companion drive must deliver.

Rotor angle is detected by a resolver with integrated encoder, supplying analog sine-cosine signals used to derive velocity and torque commands. The device also reports absolute position feedback exceeding 4096 revolutions, eliminating the need for homing after shutdowns. Cables exit toward the rear because connectors are mounted on Side B; this orientation streamlines wiring when motors are lined up on a common machine wall. Torque is delivered through a shaft with keyway, enabling standard couplings to transmit power while the key blocks slip during high-inertia reversals.
