The Rexroth R911312436 (MKD090B-035-GG2-KN) is a synchronous AC servo motor from the MKD series, featuring a flange mounting interface with a 140 mm size and 110 mm centering diameter. It uses a plain shaft with a shaft seal and is equipped with a resolver for feedback, providing relative position detection. The motor operates with winding code 035, has a rated standstill torque of 12.0 Nm, and supports a maximum speed of 5000 RPM with a rated speed of 3000 RPM. Electrical characteristics include a resistance of 1.88 Ohms, inductance of 15.5 mH, 1.22 Nm/A torque constant, and a peak current of 49.5 A. The voltage constant is specified as 111 V/1000 RPM, and the device tolerates up to 43.5 Nm theoretical maximum torque. Natural convection is used for cooling; the motor uses thermal class F insulation and has a thermal time constant of 60 minutes. Its physical parameters include a weight of 14 kg and a motor length of B. It is intended for operation with Rexroth HDS and HDD drive controllers.
