Product Description:

The MKD112C-058-GG3-AN is a Bosch Rexroth Indramat servo motor that belongs to the MKD Synchronous Motors series. In automated cells, it acts as the rotary actuator between the drive controller and the load, delivering synchronized motion for indexing conveyors, gantry axes, and spindle drives. An integrated holding brake can clamp the shaft during power loss, so the motor supports applications that require secure load retention without external hardware.

The motor develops a continuous standstill torque of 38.0 Nm, so it can hold or slowly drive mechanical loads without overheating. During emergency stops, the brake supplies up to 70 Nm of static torque, allowing vertical loads to remain in position until power is restored. Its mounting interface uses a flange that measures 192 mm, and the stator registers in a centering recess of 130 mm to maintain radial alignment with gearboxes or machine frames. All power and feedback leads exit on Side A, which can simplify cable routing when the enclosure is fixed against a bulkhead. The rotor has a plain shaft, so couplings or pulleys can be press-fitted without keys, and a factory-installed shaft seal helps keep lubricant out of the stator housing.

Winding code 058 identifies the copper fill and impedance, so current demand matches the rated output of MKD-compatible inverters. Position data is produced by resolver feedback (RSF), which provides analog sine-cosine signals for coarse and fine angle evaluation, and its relative measuring principle maintains continuity after short power interruptions. The frame size of 112 mm supports medium-inertia loads, while length designation C increases active stack height for additional torque. Connection is completed through an output connector that carries phase power, brake supply, and sensor lines in a single pluggable interface, which keeps wiring consolidated at the motor.
