R911254928
The R911254928 (MDD093A-N-030-N2M-130GB1) is a top-quality digital drive controller produced by Bosch Rexroth Indramat. This component is integral to the creation of swift and efficient automation systems when paired with digital AC servo motors like those in the MDD series. Its usage is versatile, functioning seamlessly in machine tools, printing machines, and robotic applications.
This specific model forms part of Bosch Rexroth's MDD series of maintenance-free synchronous servo motors. It features a simple output shaft, ensuring a seamless non-positive shaft-hub link with no backlash alongside a shaft sealing ring to hinder liquid intrusion along the shaft. Its closed design, boasting an Ingress Protection Rating of IP 65, guarantees protection from dust and water jet sprays. Thanks to a nominal speed of 3,000 revolutions per minute and a potential maximum torque of 28.6Nm, it performs optimally in even challenging conditions. The R911254928 (MDD093A-N-030-N2M-130GB1) owes its longevity to a brushless design and lifetime-lubricated bearing. Natural convection cools the motor, while an inbuilt thermal sensor prevents damage from temperature overload. This model also comes with an 11.0Nm torque blocking brake for secure servo axis holding when not powered. Its low inertia and 130mm centering diameter contribute to its impressive torque-weight balance.
