当加热的合金放置在永久磁铁——如稀土磁铁附近时,合金的磁力会突然戏剧性地大幅增加。
That distinguishes them from synchronous motors that use a permanent magnet in their rotors instead of a set of aluminium or copper conductors.这就把它们和在转子处使用永磁铁而非一套铝或铜导体的同步发动机区分开来。
The test program will operate the permanent magnet propulsion motor up to full power (full torque and full load) in a test facility that simulates an actual U.S.Navy DDG-1000 engine room.测试程序将在一个美海军仿真实际DDG - 1000引擎室的测试设施中操作永磁推进马达至全功率(全扭矩和全负载)。
