The R911279073 (MKD112C-024-GP2-BN) is a Bosch Rexroth synchronous servo motor from the MKD series, featuring B05 flange mounting and a B-side output connector for power supply. It integrates a temperature sensor, a holding brake connection, and an optional AC 115–230 V blower for enhanced surface cooling under high-load conditions. The motor offers a continuous torque of 38.0 Nm at standstill, with four pole pairs and a winding inductance of 6.7 mH. The shaft has a keyway and seal, with a centering diameter of 130 mm. Position feedback is provided by a resolver (RSF) for relative detection, and it additionally supports an incremental encoder with 2048 lines. The R911279073 (MKD112C-024-GP2-BN) is rated for a maximum speed of 6000 RPM, a voltage constant of 24 V, and a protection class of IP65. The motor is coated for resistance to corrosion, acids, and weather, with an operational altitude ceiling of 1000 meters. The total weight is 35.2 kg.
