R911271488
The Bosch Rexroth R911271488 (MDD112B-N-030-N2M-130GA0), a digital AC servo motor from Indramat, comes equipped with a multi-turn integrated encoder for providing digital servo feedback. This feedback, delivered with the help of a dedicated cable, includes critical motor parameters such as speed and torque - these metrics are relayed to the drive controller. The power source for the motor is supplied via a separate power cable connected to the motor's side A. While it does not come standard with a blocking brake, an additional brake can be ordered if necessary. Notably, the motor features a plain shaft with a centering diameter of 130 millimeters.
Cooling of the MDD motor is achieved through natural convection or surface cooling, influenced by the customer's load requirements. Offering higher torque and current output is possible with surface cooling, which utilizes airflow from cooling fans or blowers. Designed to work within a temperature range of 0 to 45 degrees Celsius and up to 1000 meters elevation, the motor's output reduces at higher temperatures and altitudes. The MDD motors are IP65 rated for operation in adverse conditions. With a nominal speed of 3000 RPM, Bosch advises that installation and operation of the motor should be carried out by trained personnel to mitigate installation errors and increase lifespan. Observing all safety instructions in the product documentation is also strongly advised.
