Title:
POWER TRANSMISSION OR POWER RECEPTION COIL, WIRELESS POWER TRANSMISSION DEVICE USING THE SAME AND ROTOR
Document Type and Number:
Japanese Patent JP2017070119
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a wireless power supply device capable of achieving easy detachment/re-attachment of power transmission and power reception coils from/to a rotor, high transmission efficiency between the coils and suppression of unnecessary radiation of an electromagnetic field.SOLUTION: The wireless power transmission device executes wireless power supply from a power transmission coil mounted on a rotor by magnetic coupling. At least one of the power transmission coil and the power reception coil is of a crescent shape along a peripheral direction of the rotor and excludes the rotor in a closed loop of the coil, and can be mounted on the rotor without need for deforming the coil shape.SELECTED DRAWING: Figure 1
