The R911330642 (MSK071E-0303-FN-M1-UG2-NNNN) is an IndraDyn S synchronous servomotor from Bosch Rexroth, designed with a plain shaft and a force-fit, backlash-free shaft-hub connection. This model features liquid cooling (FN), a rotatable 240-degree encoder connector, and an optical multiturn absolute encoder using the Hiperface interface with 128 signal periods. Motor length is E and size is 071. The motor includes an electrically-released holding brake providing 30 Nm torque. Continuous current at standstill (100 K) is 15.2 A, continuous torque at standstill is 28.0 Nm, maximum current is 56.3 A, and maximum torque is 84.0 Nm, with winding inductivity of 5,900 mH. It incorporates safety components aligned with EU directives and requires appropriate cable connections and power disconnection during servicing.
