R911261808
The R911261808 (MDD093C-N-030-N2M-110PB2) servo motor, originating from Bosch Rexroth Indramat, is built to facilitate a maximum shaft speed of 3000 RPM. The motor boasts two cooling methods, namely convection and forced air cooling. While convection cooling proves efficient and cost-effective, forced air cooling requires a fan, resulting in higher costs but boasting better heat dissipation. Depending on the cooling method, the motor delivers varied levels of output torque and current at standstill – 19.5 Nm and 32.2 Amps for convection cooling, and 20.8 Nm and 34.3 Amps for forced air cooling. The R911261808 (MDD093C-N-030-N2M-110PB2) model also comes fitted with a 22Nm blocking brake, a safety feature that prevents the shaft from rotating unexpectedly, releasing only upon the application of a 24Volts DC signal.
The motor’s shaft includes a keyway, designed to hinder relative rotation between the linked machinery and the shaft itself. The magnetically-installed seal aids in keeping out moisture and dust. Bosch offers a selection of six encoders for the motor, the model in question is equipped with a multiturn encoder, providing digital servo feedback. The servo motor's protection is covered up to the IP65 category. It has a centering diameter of 110 meters and is flange-mounted, with holes present for secure mounting. For appropriate handling and operation, Bosch recommends highly skilled and trained technical personnel.
