R911252007
The R911252007 (MDD093B-N-030-N2L-110GL0) is a Bosch MDD series servo motor, designed by Bosch Rexroth Indramat for diverse industrial uses in conjunction with compatible Bosch controllers such as the DDS series. As a synchronous motor, its shaft speed matches the input current frequency, powered through a power connector located on the left side of the housing. Notably, the R911252007 (MDD093B-N-030-N2L-110GL0) has digital servo feedback, sending speed and torque data back to the controller via a separate cable. The centering diameter measures at 110 millimeters and includes a plain shaft configuration with the option to order a shaft with a keyway if needed.
This motor features a standard B end shaft and balance class, encased in a housing designed for both surface cooling and natural convection. When surface cooled, it outputs 33.2 Amps continuous current at standstill and 20 Nm continuous torque. This decreases to 24.1 Amps and 14.5 Nm torque with natural convection. With a nominal speed rating of 3000 RPM and a class F insulation, it functions optimally in 0 to 45 degrees Celsius. Covered in a black paint layer, the servo motor offers an IP65 protection category, guaranteeing protection from dust and low-pressure water jets. However, it does not include an optional blocking brake.
