RDD-Series Direct Drive Motors
RDD-Series™ (Bulletin RDB) direct-drive servo motor design
provides direct-coupling to the load, thus improving system
performance and efficiency by eliminating the need for inefficient
mechanical power transmission devices, such as gearboxes, timing
belts and pulleys. The initial RDD-Series offering incorporates a
bearingless housed configuration designed for applications where the
load is already supported by its own bearings.
