Split-Ring Wireless Power Transfer

Split-Ring Wireless Power Transfer Module Enables Easy Retrofit on Rotating Equipment

Delivering Power to Rotating Systems Through Non-Contact, Retrofit Installation

We have developed a new split-ring wireless power transfer module that can be retrofitted onto existing rotating shafts. Unlike conventional slip rings, the system contains no wear-prone contact parts, providing stable power transmission with no adjustment, minimal maintenance, and long service life.

The Future of Power Supply for Rotating Equipment: Wireless and Contactless

The demand for supplying power to rotating equipment such as index tables, robotic end effectors, and rotary fixtures continues to grow across industrial applications.

However, conventional slip rings often present several challenges:

• Maintenance and replacement costs caused by wear
• Failures due to poor electrical contact
• Increased installation and maintenance work

As a result, there is a growing need for reliable, maintenance-free, non-contact power transmission technology.

Advantages of the Split-Ring Design

1. Easy Retrofit Installation with Split-Ring Structure

The split-ring design allows the module to be opened and installed around an existing shaft without disassembling the equipment. This significantly reduces installation time and labor.

2. Wireless Power Transfer Without Slip Rings

Power is transmitted wirelessly without physical electrical contact, eliminating wear parts and enabling maintenance-free operation with extended service life.

3. Ready to Use with No Complex Setup

No complicated tuning or calibration is required. Stable power transmission can be achieved immediately after installation.

4. Optimized for Rotating Applications

The ring-shaped structure allows unrestricted 360-degree rotation, making it ideal for rotating mechanisms such as index tables, robotic systems, and rotary equipment.

Typical Applications

• Rotary fixtures for index tables
• Rotary inspection equipment
• Rotating lighting and display systems
• Rotary sensor units

Future Development

This technology introduces a new approach to powering rotating equipment through non-contact, retrofit, and maintenance-free operation.

We will continue to enhance the technology with further miniaturization and higher power capability, expanding its use in industrial machinery, robotics, inspection systems, and many other applications.
