大功率电磁炉电磁仿真初步结果电子科技大学 物理电子学院，大功率电磁炉课题组 2006-6-16（本分析还未加入磁条的非线性，未进行热分析和结构参数扫描。

仅为给定结构下，不同激磁频率下的工作奖状态的初步电磁仿真）1．EM-OVEN-Model 电磁炉模型图1。

电磁炉仿真结构图：兰色表示锅底，红色表示线盘，粉红为磁条铁氧体磁块参量：Magnet: [15×5×60mm,Ф=190mm,Epsilon=1.0, Mue=2300, Conductivity=0.167S/m, Density=4800 ka/m^3, Thermal conductivtity=0.1 W/[k m] ]线盘：Coil:[R_in=21mm,R_out=68.56mm, （Ф190mm）：ф0.31×28，Turn= 29, Epsilon=1.0, Mue=1, Conductivity=5.8e007S/m]锅底：Pan: [R=78mm, h_pan=1mm,Epsilon=1.0, Mue=1, Conductivity=1.1e006S/m]2．磁能量分布在f＝15KHz时。

a.图2磁能量分布at 15KHzb. 图3磁能量分布at 25KHzc. 图4。

磁能量分布 at 35KHz说明：涡流的分布呈6边形，与线圈底部的磁条分布位置是一致的，推论如果要提高涡流的分布的均匀性可改变磁条分布。
