Title:
SOLENOID COIL UNIT AND CONTACTLESS POWER FEEDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/097699
Kind Code:
A1
Abstract:
This solenoid coil unit comprises: a solenoid coil placed in parallel with another solenoid coil but apart therefrom by a predetermined separation distance in a separation direction orthogonal to the center axis direction; and a rod-shaped core around which said solenoid coil is wound and which is longer than the length of said solenoid coil in the center axis direction. The rod-shaped core has: a center part around which the solenoid coil is wound; end parts that are located at opposing ends of the rod-shaped core and extend from the opposing ends of the solenoid coil. The ratio of the length to the width of the center part is 2 or more. The length of the solenoid coil in the center axis direction is substantially twice the separation distance.
