Wireless energy emission mechanism based on concave-convex magnetic core and parameter design method thereof

The invention belongs to the technical field of wireless energy transmission, and provides a wireless energy emission mechanism based on a concave-convex magnetic core and a parameter design method thereof. The mechanism comprises a magnetic core and a coil, and the magnetic core is consists of a plurality of ferrite magnetic strips which are distributed in an annular array, the upper surface of each magnetic strip is provided with two sections of concave-convex parts, After the plurality of magnetic strips are distributed in an annular array, the concave-convex parts form two annular coil accommodating grooves, and the coils are divided into two groups and are respectively wound in the two coil accommodating grooves in a plane-tight manner. And the inner and outer groups of coils are connected in series. The simulation software analysis shows that the structure can realize that the transverse anti-offset capability and the longitudinal transmission distance at the other mutual inductance end are obviously su
