Abstract

A coil for a non-contact power transmission system according to the present disclosure is used in a non-contact power transmission system to transmit electric power via a non-contact method. The coil includes a magnetic body with a flat cross section, and a wire wound around the magnetic body. The wire is wound around a shorter side surface of the magnetic body at a predetermined angle with respect to a direction perpendicular to a longer side surface of the magnetic body.

Claims

1. A coil for use in a non-contact power transmission system to transmit electric power via a non-contact method, the coil comprising:

a magnetic body with a flat cross section; and

a wire wound around the magnetic body, wherein

the wire is wound around a shorter side surface of the magnetic body at a predetermined angle with respect to a direction perpendicular to a longer side surface of the magnetic body.

2. The coil for the non-contact power transmission system of claim 1, wherein

a surface of the wire is covered with an insulator, and

on the short side surface of the magnetic body, the predetermined angle falls within a bending tolerance range in which the insulator is not damaged.

3. The coil for the non-contact power transmission system of claim 1, wherein

the predetermined angle falls within a range from 10 to 60 degrees.

4. A non-contact power transmission system comprising:

a power supplier including a power transmitting coil; and

a power receiver including a power receiving coil, wherein

the power transmitting coil and/or the power receiving coil are/is the coil for the non-contact power transmission system of claim 1.
