提供一种稀土类磁铁以及永磁电动机，该稀土类磁铁可以兼具高顽磁力和高剩磁通密度。
The object of the present invention is to provide a rare earth magnet which enables to achieve a good balance between high coercive force and high residual magnetic flux density, and a magnet motor.
降低磁通门剩磁误差的有效方法是增大激励电流的峰值，但大的激励电流峰值将增大功耗。
An effective method for low perming error of fluxgates is to enlarge the peak value of the excitation current, but large amplitude excitation will increase the power consumption.
作用于磁化材料以去除剩磁的反向磁通强度。
The opposing magnetic intensity that must be applied to a magnetized material to remove the residual magnetism.
