Product Description:

The MKD112D-027-GP0-RN belongs to the MKD Synchronous Motors series produced by Bosch Rexroth Indramat. It is an AC servo motor intended for closed-loop motion axes where repeatable torque delivery and accurate rotor position are required for machine tools, packaging stations, and handling robots. By combining the standard MKD electromagnetic design with a resolver feedback interface, the unit links directly to Indramat digital drives so position, velocity, and torque loops are closed inside the controller for industrial automation tasks.

The motor supplies a continuous standstill torque of 48.0 Nm, so a driven axis can hold load without external gearing while current stays within the continuous rating of the drive. Its square mounting interface uses a 192 mm flange, and concentric alignment to the gearbox or load is supported by a 130 mm centering diameter. Rotor position is reported through resolver feedback (RSF), a low-maintenance sensor that withstands vibration and temperature changes while providing absolute angle within one mechanical revolution. An IP65 housing blocks dust and low-pressure water jets, allowing cabinet-free installation near the working process. Class F insulation tolerates winding temperatures up to 155 °C, extending service life under cycles that generate elevated copper losses.

Cabling is routed to the right side, where a power connector carries phase conductors and a protective ground, simplifying parallel mounting of multiple motors on one frame. The unit operates in ambient air from 0 to 40 °C without derating, so standard plant HVAC is sufficient for thermal management. A shaft with a keyway transmits torque through positive mechanical engagement, and a radial shaft seal guards the bearing cavity against coolant splash. System repeatability is specified at ±8 angular minutes, supporting indexing tables or gantry axes that rely on relative position detection to maintain coordinated paths across successive machine cycles.
