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. 3 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.

All rights reserved. 4 What are the benefits of Direct Drive Motors? • Increased Machine Throughput – Direct Coupling of Motor to Load Eliminates Compliance and Backlash • Better control of the load • More responsive system • Optimal system performance • Increased Customer Product Quality – Significant Improvement in System Accuracy • Lower Energy Consumption – Reduced Mechanical Losses • Friction • Heat • Noise – No Inertia Matching • “Right-size” the power for the application Key Benefit: Increased System Performance and Efficiency Copyright © 2008 Rockwell Automation, Inc. All rights reserved. 5 What are the benefits of Direct Drive Motors? • Simplified Mechanics – Eliminates Components that Wear over Time • Stable long-term accuracy • Higher reliability • Consistent quality – Reduced Maintenance (lubrication, belt tensioning, tuning, etc.) • Increased productivity • Reduced scrap – Lower Overall Part Count • Lower purchasing burden • Faster assembly • Reduced spare parts inventory • Smaller machine footprint • Reduced Commissioning Time – Simplified Tuning Key Benefits: Increased System Reliability, Lower Total Cost of Ownership Copyright © 2008 Rockwell Automation, Inc. All rights reserved. 6 Rockwell Automation Direct Drive - Benefits • Integrated Architecture – Single source solution – Single programming environment – Smart Motor Technology (“plug-n-play”) • Motion Analyzer Integration – Simplified / optimized sizing and selection • Old “rules of thumb” not sufficient to get full utilization of products – Mechatronics Capability • Import 3D CAD files (SolidWorks) • Mechanical animation and simulation • Tuning simulation – Database with Drive Compatibilities • Catalog numbers • Speed / torque curves Copyright © 2008 Rockwell Automation, Inc.
