铁磁性

The intensity of the magnets in permanent-magnet motors can increase as the motor size and output power increase. This causes difficulty in manufacture of large scale PM motors and consequently increases the cost. Post-assembly magnetization can be treated as a solution to the above problem, which fabricates the motors before the magnet is magnetized by applying large current impulse on the motor stator windings.

中文摘要由於永磁马达转子磁铁强度，会随著马达尺寸与输出功率增加而增加，导致大型永磁马达在制作上，因磁铁的强磁性造成组装上的困难，且易有铁粉等杂物附著，使得制作成本增加，故有必要使用新的充磁技术或特殊制程解决。

The M-H behavior has displayed a ferromagnetic hysteresis loop with a wasp-waisted shape, which constricted in the middle section, while wider at above and below section.Further, various amount (1, 3, 5%)of NdFeB were mixed with Ni-Zn ferrites. The M-H behavior has shown markedly different coercivity and wasp-waisted hystsresis.
