国家限制稀土出口的政策,引发了一系列连锁反应,其中永磁产业最受瞩目,它是否会成为下一个投资热点?无论对于动力汽车、风电机组,还是各种家用电器来说,作为以磁场转换机械能和电能的电机装置都是最为重要的组成部分。传统的电机采用通电流的方式产生磁场,也就是所谓的电励磁。另一种方式则是以不需外加能量的永磁体来产生磁场。这种所谓的永磁电机没有励磁绕组和直流励磁电源,结构更简单,运行更可靠,损耗更少,应用也更广泛,已成为投资领域追逐的热点。
National policy of limiting exports of rare earth, triggered a series of chain reactions, of which the permanent magnet industry, the most watched, it will become the next investment hot spot? Whether for electric vehicles, wind turbines, or various household appliances, as a magnetic field Electrical devices that convert mechanical and electrical energy are all the most important components. The traditional electric motor uses the current through the way to produce a magnetic field, which is the so-called electric excitation. Another way is to generate a magnetic field with a permanent magnet that requires no external energy. The so-called permanent magnet motor without excitation windings and DC excitation power supply, the structure is simpler, more reliable operation, less wear and tear, the application is also more extensive, has become a hot investment chase.
