Product Description:

The MKD112C-058-GG0-LN servo motor belongs to the MKD Synchronous Motors series manufactured by Bosch Rexroth Indramat. This AC servo unit is intended for closed-loop positioning and speed control in automated machinery such as gantry axes or packaging lines. By integrating with Rexroth digital drive controllers, the MKD112C-058-GG0-LN converts electrical energy into precisely controlled rotary motion that drives load elements with repeatable accuracy.

The mechanical interface begins with a centering diameter of 130 mm, seated inside a flange that spans 192 mm; together they align the housing to gearboxes or direct couplings without lateral runout. At the stator, the MKD winding code 058 supports a continuous standstill torque of 38.0 Nm, allowing the axis to hold load torque while maintaining servo stiffness. Motion feedback is supplied through resolver feedback, which provides rotor position data so the drive can monitor and regulate motion during operation. The motor is sealed to IP65, preventing dust ingress and protecting against low-pressure water jets, so it can be mounted outside control cabinets on process equipment. All power and feedback plugs exit on the left side, simplifying cable routing when multiple axes are lined up.

The thermal design relies on Class F insulation, allowing winding temperatures up to 155 °C while ambient temperature remains within 0 to 40 °C; this margin supports intermittent overloads without accelerated insulation aging. A plain shaft with a shaft seal transmits torque directly to couplings, and the seal keeps contaminants out of the front bearing while retaining grease. Relative position detection derived from the resolver limits cumulative error to ±8 angular minutes, matching the precision needed for indexing tables and mechanical presses. The motor does not include a holding brake, so machinery that requires static holding torque must use an external clamping device.
