The Bosch Rexroth R911311188 (MSK071E-0300-NN-S1-UP1-NNNN) is a self-cooling synchronous servo motor from the MSK series. Noted for its compact build, accuracy, and significant torque density, it is a component of the Rexroth IndraDrive system. With a bearing lifespan of 30,000 operating hours, it promises maintenance-free performance within predefined operating conditions. Its advanced integrated encoder, compliant with the Hiperface interface, offers a system accuracy of ±80 angular seconds and records the absolute indirect position within one mechanical rotation in its data memory. This allows for swift and simplified bootup. It operates efficiently with natural convection cooling, transferring heat to the surrounding air and machine walls. Rated IP 65 per EN 60529, it is apt for challenging environmental conditions with resistant housing. The motor features an electrically-released holding brake with a holding torque of 23Nm, ensuring stability during power shutdowns. Its output shaft conforms to DIN 6885-1(DIN 3760 –design A). The shaft enables effective torque transmission and requires fewer requirements on the shaft-hub connection.
