摘要
先将永磁转化为普通电磁铁的形式 ,推导出永磁磁路的表达方程式 ,绘出永磁的等值磁路图 ,再推导出控制线圈磁势与永磁磁势关系的方程式 ,然后阐述各种控制方案的优劣 ,并为双稳态永磁机构提出一套计算方法。
Through converting the model of permanent magnet into the one of common electric magnet,an expressive equation of magneto motive force and its equivalent circuit are obtained for the permanent magnet.The equation of magneto motive force of the control coil with the permanent magnet is then deduced from them.Some control schemes are analyzed.
