The Bosch Rexroth R911262509 (MDD090B-N-040-N2M-110PA2) is a digital AC servo motor designed for use with digital drive controllers. It features an integrated multiturn absolute encoder utilizing an optical measurement system and provides digital servo feedback (DSF). This model, with housing and centering diameter of 110 mm, supports a maximum nominal speed of 4000 min⁻¹ and offers 7.2 Nm continuous torque at standstill. The holding brake provides a torque of 11.0 Nm. The shaft is a standard keyway type with shaft seal, following DIN 42955 for concentricity and coaxiality. Connections are made using side A connectors for power and feedback cables (up to 75 m), which are supplied separately. The device is suitable for high synchronism applications and performance may decrease between 45°C and 55°C. The bearing life is limited under high radial loads. The motor should be kept dry during transport and must not be lifted by the blower.
