Description
技术领域
本发明涉及永磁电机技术领域,特别涉及一种制造永磁电机的永磁材料。
背景技术
所谓永磁体的耐热性是特指其磁性能不因温度的升高而劣化。在接近机器发热源的设备上使用钕铁硼磁体,要求随使用温度升高而磁性能不恶化,即剩磁 Br 不恶化,但在磁体使用温度达 200℃附近的场合 ( 如汽车引擎周边及一些磁体须高温焊接及粘胶固化 ),则只有使用 Sm-Co 磁体,通常烧结钕铁硼类磁体不能在这样的高温下使用。通常烧结钕铁硼的居里温度只有 320℃左右,且温度系数较大,如剩磁的温度系数为 -0.11 ~ -0.126%,矫顽力温度系数为 -0.6 ~ -0.8%,通常其工作温度较低。随着稀土磁体应用范围的不断扩大,如汽车启动电机、马达类产品及集成化 CO-ROM 对烧结钕铁硼需求范围的扩大,在目前小型化设备下,对高温下磁体的性能提出了更高的要求。
