Increasing Efficiency, Flexibility, and Safety
Haworth Improves Automation Safety and Flexibility with Contactless Power Transfer
Haworth, a leading office furniture manufacturer, sought to automate its wrapping and shipping area to improve material flow and reduce manual handling. The application required an accumulation conveyor system with transfer carts moving product between multiple wrapping stations.
By partnering with SEW-EURODRIVE, Haworth implemented a contactless power transfer system using MOVITRANS® technology. This approach eliminated the need for overhead power, enabling a safer, cleaner, and more flexible automation layout.
Challenge:
Eliminating Overhead Power While Maintaining Safety
Haworth needed to automate its sorting and transfer area without introducing safety risks or limiting system flexibility. Traditional power methods would have required overhead cables or bus bars, creating hazards and restricting product height. At the same time, the facility relied on existing AGVs and had concerns about potential interference with their guidance signals from a new power system, so that the new system would require a performance test before launch.
- Avoid overhead electrification across moving transfer carts
- Maintain safe operations for personnel & equipment
- Prevent interference with existing AGV guidance systems
- Handle tall, delicate furniture loads without damage

Solution:
MOVITRANS® Contactless Energy System
SEW-EURODRIVE delivered a complete solution centered on MOVITRANS contactless induction power transfer, combined with decentralized drive technology.
This approach provided reliable power delivery from the floor while enabling safe and precise motion control.
-
Contactless power transfer: Energy supplied from a floor-mounted system, eliminating overhead wiring
-
Flexible layout: Transfer carts move freely between multiple stations without routing constraints
-
On-site proof of concept: Live demonstration validated performance, confirmed no signal interference
-
Decentralized motion control: MOVIMOT® drives with encoder feedback enable precise positioning
-
Integrated system solution: Combined power transfer, gearmotors, and controls from a single supplier

"From a maintenance standpoint, Haworth has seen major improvements in safety, reliability, and uptime by eliminating cords and trip hazards — especially wires draped across the floor in high-traffic areas." - Phillip Falstrom, Haworth, Sr. Electrical Technician |
Results:
Contactless Energy Transfer Improves System Safety and Design Flexibility
The implementation of MOVITRANS enabled Haworth to successfully automate its wrapping and transfer system while improving safety and flexibility.
By opting for a floor-level inductive power system over traditional overhead power, Haworth eliminated key safety, design, and operational concerns.
Results included:
- Removed height restrictions for tall product handling
- Reduced layout constraints and cable management complexity
- Verified no AGV interference through on-site proof of concept
- Enabled smooth, controlled handling of delicate loads
- Created a flexible, scalable system for future growth

"SEW-EURODRIVE helped us rethink how power is delivered on the floor as well as simplify the overall setup. Demonstrating the solution in our own environment prior to installation gave us the confidence it would hold up day to day. With fewer failures and less time spent dealing with power-related issues, we’re now able to focus our efforts on improving reliability elsewhere in the operation while moving forward with a safer, more flexible case goods transferring system." - Phillip Falstrom, Haworth, Sr. Electrical Technician |
