R911248855
The R911248855 (MDD093C-N-030-N2L-110PA1), a servo motor with a speed rating of 3000 RPM, is a Bosch Rexroth Indramat product that boasts the option of an 11 Nm blocking brake. The brake, which serves as a safety feature preventing shaft rotation when stationary, operates through an electrically-actuated release mechanism which only liberates the shaft after a 24 Volts DC signal is issued. The mechanisms draw a current of 0.5 Amps with a release and clamping delay of 60 and 20 milliseconds, respectively. You can also find options with 22 Nm brakes for MDD093 motors. Designed with the power socket on the housing’s side A, the main shaft includes a keyway, while options with plain shafts are available too. The R911248855 (MDD093C-N-030-N2L-110PA1) is principally a flange-mounted device.
Featuring a 140mm flange with each of the four mounting holes measuring 11mm in diameter, the R911248855 (MDD093C-N-030-N2L-110PA1) servo motor has a centering diameter of 110mm and a motor housing length of 386mm. It is specifically designed for surface cooling and natural convection, capable of operating under both conditions with an output torque rated at 20.8 Nm (surface cooling) and 19.5 Nm (natural convection), while its rated current output is 46.2 Amps and 32.2 Amps respectively. The R911248855 (MDD093C-N-030-N2L-110PA1), though designed with IP65-class protection, is recommended for professional handling and installation to reduce potential errors.
