The R911311766 (MKD090B-035-KP2-KN) is a Bosch Rexroth synchronous servo motor from the MKD series, designed with a shaft featuring a keyway and a DIN 3760-compliant rubber shaft sealing ring. This motor supports both radial and axial forces and is equipped with bearings tested for a typical lifespan of 30,000 operating hours under standard load conditions. The unit incorporates a resolver with integrated encoder for absolute position detection exceeding 4096 revolutions. It offers a rated torque of 28 Nm, continuous standstill torque of 12.0 Nm, and a winding inductance of 5.26 mH. The MKD090B-035-KP2-KN features class F insulation, four pole pairs, IP65 protection, a 140 mm flange (secured by four M10 screws in accordance with DIN 42950), and a side B connection direction. The specified voltage constant is 98 V/krpm and nominal power is 6.0 kW. The motor weighs 22 kg and is intended for operation exclusively with Bosch Rexroth drive controllers in clean environments, with power connectors handled only when de-energized. For storage and transport, a horizontal orientation is required and immediate mounting is necessary after shaft sleeve removal.
