R911271845
The R911271845 (MDD112C-N-030-N2M-180PA0), a product from Bosch Rexroth Indramat, is a servo motor with a nominal speed of 3000 revolutions per minute. The motor is of size 112 and length C. The feedback mechanism is a digital servo with an integrated multi-turn absolute encoder. The motor exhibits a unique 180mm pilot centering diameter and an output shaft driven with keyway for form-fitting torque transmission. Notably, the motor lacks a holding brake and is designed to provide exemplary performance in normal applications, thanks to its balance class. The power connector is positioned on the side A of the motor.
The R911271845 (MDD112C-N-030-N2M-180PA0) servo motor has a continuous current of 43.4 Amps at standstill and offers 28 Nm continuous torque during the same condition. Operating at 20 degrees Celsius, the motor’s constant torque is 0.65 Nm/A and peaks at 166 amps. Weighing 48 kilograms, the motor has a 0.14 Ohm windings resistance at 20 degrees Celsius. Constructed with lifetime lubricated bearings and a brushless design, the motor requires no maintenance and can be oriented in any mounting position. Its standard housing ensures optimal temperature maintenance, and the prime black coating on the housing resists yellowing or chalky build-ups. For enhanced cooling, a surface cooling unit may be added.
