Copyright © 2008 Rockwell Automation, Inc. All rights reserved. 3 What is a Direct Drive Motor? Direct Drive Motor: Any motor whose design is specifically intended to allow for direct-coupling to the load, thus improving system performance and efficiency by eliminating the need for additional mechanical transmission components.

All rights reserved. 4 Realize the benefits of a Mechatronic Solution The RDD-Series Rotary Direct Drive Motors are part of the Rockwell Automation mechatronic solutions portfolio. Mechatronic design is a collaborative venture between mechanical, electrical, and control design engineers – the outcome is a machine design optimized for high performance. The Rockwell Automation mechatronics offering includes: virtual design tools, products and expertise. Mechatronic products like the RDD-Series Motors provide tighter coupling between the control and machine function, and help eliminate backlash, compliance, noise and energy losses.
