Abstract

For the adaption to the development of hardware technology and meet social demands, it becomes urgent to research the magnetic of charging coil for hardware. The Ansoft Maxwell3D was used to build different kinds of magnetic of charging coil mathematical models and to set a series of factors. The finite element method was used to get the inner magnetic distribution of charging coil. Then the MATLAB was used to analyze the results that came from Maxwell3D, the magnetic flux density spatial distributions diagrams were exported and they were analyzed entirety. Finally the conclusion was completed the same as the actual result. The magnetic field characteristics of magnetic of charging coil was researched fully, so it is benefit to increase the product technology and optimize magnetic characteristics, therefore, the product quality is improved and the product competitive power is advanced. What's more, a condition that research hardware magnetic field deeply is created.
