Wireless Power Transfer Technology Robust to Misalignment Shindengen Electric Manufacturing

・Engineers and designers developing small mobility systems and robotics
・System designers for AGV/AMR, service robots, delivery robots

The key requirement for wireless power transfer is the ability to deliver power reliably in a hands-free manner.
Looking toward the future of small mobility solutions and service robots, we are advancing research and development for low-power applications by leveraging wireless power transfer technologies cultivated for electric vehicles.
Magnetic field coupling wireless charging technology, when applied to robotics, offers strong tolerance to positional misalignment, maintaining stable charging performance even when some deviation occurs.
In addition, depending on the application, you can select the optimal configuration from two methods—magnetic coupling and electric coupling—both of which enable thin, lightweight, and layout-free design.
