Direct-drive motors help improve machine performance and efficiency
Machine designers are increasingly implementing direct-drive technology to build high-performance machines that require less energy, are easier to maintain and can quickly accommodate changes – at the same or lower cost as machines built with traditional motion control solutions.

Since eliminating power transmission devices reduces power wasted in the form of heat, friction and noise, direct-drive technology can often allow machine designers to use a smaller motor and drive that require less current, which helps lead to an overall increase in system efficiency.
The initial RDD-Series offering, the Bulletin RDB, incorporates a bearingless housed configuration designed for applications where the load is already supported by its own bearings, such as unwind/rewind stands, web guides and print, nip and feed rolls. The bearingless configuration simplifies installation for these applications while minimizing package size and alleviating alignment issues between the motor and the load.
Future configurations will include fully housed models, where the motor is capable of completely supporting the load, and frameless part sets for applications with high power requirements or tight space constraints.
As with all RDD-Series configurations, the Bulletin RDB bearingless motors feature windings optimized for use with the latest Kinetix servo drives, as well as multiple speed options, Heidenhain high resolution absolute encoders and rotatable DIN connectors.
