永磁2T磁路设计方法
技术领域
本发明申请属于磁力研究与应用领域,具体是一种稀土永磁体通过铁铠和极头聚集磁通而产生的高磁感应强度的方法,可用于试验研究和工业生产。
背景技术
常温2T磁感应强度在电磁领域容易实现,并已广泛应用,但由于其耗电量大,结构复杂,冷却系统复杂,限制其应用,低温超导技术能取得很高磁场,又需要庞大的低温设备来保障运行,本发明申请是一种常温永磁磁系的设计方法,目标是在常温下实现大于或者接近2T的磁感应强度。
发明内容
图1是永磁2T磁路设计方法的结构图,图1的1是铁铠,2是梯形铁,3是磁场区,4是背磁板,5是磁体。
铁铠1,其材料是电工纯铁厚板,分两个挡边与两个背磁板4构成矩形铁铠。
梯形铁2,其材料是电工纯铁厚板制成的正梯形部件,其梯形下部尺寸与磁钢布局尺寸相等,其梯形上部尺寸经计算与模拟取得,以实际试验值为准。
磁场区3,可实现均匀高磁感应磁场。
背磁板4,是磁体5敷设的基础板,材料为电工纯铁,实际设计中可一块固定一块活动,实现磁场调节。
磁体5,为偶数排布的正方形磁钢,其特征是其中一块磁体排布的磁极皆为N,则另一块磁体排布的磁极皆为S。
当梯形铁2与磁体结合,并如图1方式构成铁铠形式时,由导磁性能大于2T的梯形铁将永磁磁场的磁能聚集,在铁铠包围下减少漏磁,同时反应在梯形铁梯形顶部对应的区域可产生均匀的N、S极强磁场。
