The Bosch Rexroth R911311681 (MSK050C-0300-NN-M2-UP0-RNNN) is an MSK series synchronous servomotor. It operates at a maximum speed of 4300 RPM, with a frame size of 050 and a motor length of C. The standstill torque (60 K) is 3 Nm, while the standstill current (60 K) is 1.8 Amps, both of which slightly increase to 3.4 Nm and 2.0 Amps respectively at 100 K. This servomotor manages a maximum current of 7.2 Amps and can exert a maximum torque of 9 Nm. It comes with an optical multi-turn absolute encoder with 2048 signal periods and a keyway and sealing ring shaft configuration. The servomotor doesn't include a holding brake, however, it can be purchased separately. Sporting a black, IP65-rated housing, the motor is protected against dust and moisture and has enhanced run-out and concentricity. The rotating power and feedback connectors allow natural convection cooling, which can be augmented with forced air cooling. The motor's weight is approximately 4 kilograms.
