R911270311 (MDD115D-N-020-N2M-130PA2)

Description

The Bosch Rexroth R911270311 (MDD115D-N-020-N2M-130PA2) is a model from the MDD series of digital AC servo motors, equipped with digital drive controllers from Indramat. These motors, with rare-earth or iron oxide magnetic rotors, are ideal for high-speed applications requiring high contouring accuracy. This model boasts a high overload capability due to efficient heat transference from the windings to the housing, coupled with a thermal sensor to monitor temperature and prevent damage from overloading. With a nominal speed of 2000 RPM and a balancing class N as per DIN VDE 0530 regulations, this motor is well-suited for normal use. It includes a 130mm centering diameter and a favorable torque-inertia ratio from its 271 x 101 Kg/m^2 moment of inertia. Position detection is accomplished through a digital servo feedback featuring a built-in multiturn absolute encoder. The motor's sealed housing allows for operation in adverse environmental conditions.
