B&PLUS Inc. (Head Office: Saitama Prefecture) has developed a new split-ring wireless power transfer module that can be retrofitted to rotating shafts. It achieves stable power transmission without the need for any wear parts like slip rings, requiring no setup and being completely maintenance-free.
This technology will be showcased at Booth No. 1 Hall 9-13 at "Manufacturing World Nagoya: Mechanical Components & Materials Technology Expo," held at Port Messe Nagoya from Wednesday, April 8th to Friday, April 10th, 2026.
## The Era of "Contactless" Power Supply for Rotating Bodies
The demand for power supply to rotating bodies, such as index tables, robot hands, and rotating jigs, is increasing year by year. However, conventional slip rings have unavoidable challenges:
- Replacement costs due to wear
- Troubleshooting due to poor contact
- Increased installation man-hours
Against this backdrop, there is a growing need for contactless, maintenance-free power supply technology.
## Benefits of the Split-Ring Design
1. Split-ring structure that "opens up" for retrofitting
No need to remove the shaft; can be installed on existing equipment in a short time.
Significantly reduces installation man-hours.
2. Wireless power transfer without slip rings
Transfers power wirelessly, resulting in zero wear parts.
Achieves maintenance-free operation and long lifespan.
3. No setup required, ready for immediate use
No complex adjustments or calibrations needed.
Stable power supply is available immediately after installation.
4. Optimized ring shape for rotating bodies
Does not impede 360° rotation, making it ideal for rotating mechanisms with shafts such as index tables and robot hands.
## Main Applications
- Rotating jigs for index tables
- Rotary inspection devices
- Rotating lighting/displays
- Rotating sensor units
## Future Development
This technology represents a new approach that evolves power supply to rotating bodies towards "contactless, retrofittable, and maintenance-free." Going forward, the company plans to further miniaturize and increase output, expanding its application to a wide range of fields including industrial machinery, robots, and inspection equipment.
