【摘要】 根据“均匀磁化”原理,用谐波分析的方法,分别对多体扇形及梯形磁体构成的两类环状系统的场形进行了分析。给出了它们空间任一点的三维表达式。同时还给出了多极场主波、寄生谐波,以及外部杂散磁场的二维解析表达式。对扇形及梯形磁体的优劣作了比较。更多还原

【Abstract】 According to the principle of the "uniform magnetization" and harmonic analytic method, the fields of the ring structure system with multi-segmented and trapezoidal magnet are analysed. The 3-dimensional expression of the field at any point of the space is given, and the 2-dimensional expression of the fundamental component of multipole, harmonic and leakage field is also given.The comparisons between the property of segmental and trapezoidal magnet are discussed.更多还原
