R911255482
The Bosch Rexroth Indramat R911255482 (MDD090C-N-040-N2L-110PB1) is an AC servomotor from the MDD range, recognized for its specific radial force, contingent on the force's point of application and overall speed. Equipped with a 6.5Nm blocking brake that functions on a closed-circuit principle, the motor operates optimally at a speed near 100rpm. The blocking brake is instrumental in holding the motor’s servo axes securely when the machinery it occupies is switched off. The device flaunts a normal balance class and can be connected via a straight or angle connector for feedback.
Key features include standardized electrical connections and an integrated temperature sensor in the windings, ensuring the efficiency and safety of operations. It is necessary to connect the motor to a blower using a protected motor switch when needed. The feedback connector's output direction can be altered by merely adjusting four fixing screws. The motor's unique capability includes digital servo feedback with relative indirect position evaluation, with crucial technical details mentioned on the type plate. The device demonstrates its torque-limiting data and speed-limiting data via its operational curves. Other specifications include a 15-minute maximum duty cycle time, a blocking brake with a 24VDC +/-10% nominal voltage rating, and a 0.5A nominal current rating. Furthermore, it has a 19.9A phase current under natural convection cooling mode and weighs 23kg without the blocking brake and blower. The manufacturer advises against axial surface cooling if angle feedback connectors are in use.
