Rare earth is a kind of Permanent magnet formed by processing of high temperature steam and pneumatic agglutination by metal powder of neodymium, iron boron, dysprosium, cobalt, praseodymium, copper. Magnetism tile after the process of preventing high temperature aging and electric magnetizes can get magnetic force **0 time of its own weights. The generator made of material of this permanent magnet is called Rare earth permanent-magnet generator. A rare earth permanent-magnet generator makes electric magnetic by the process of its own magnetic field cutting stator winding magnetic field. Characteristic and principle 1. degree of distortion Wave distortion factor of traditional generator is between ±****5%,and that of rare earth generator is only between ±**4%. This provides a great field of application, especially where high electricity quality is needed (such as : Telecommunication, army, bank , computer etc. ) 2. Power factor: Because of slit between rare earth magnetism tile and inner loop of stator, the power generated by rare earth generator surpasses it by traditional generator by far. So two same power generators, traditional and rare earth ones, offer considerable differences in performance. In comparison with other power generators the rare earth one has stronger power and good energy conservation. When leading resistive load, it can conserve about *5% of the energy ,and when leading perceptual load, it comes to *0%. 3. No need to maintenance Because of its simple structure without carbon brush, exciting winding, modulator ,electronic primary device, and its long using time, the rare earth generator bring great convenient to the customer and save a lot of maintenance expense . No exciting winding and electron causes no spark or radio frequency interference, so the rare earth generator is suitable to high-quality mine pit, chemical industry and dangerous situation.
