In high working temperature situations over 180 ºC,neodymium magnet are not performance well as samarium colbalt magnets. thus samarium cobalt magnets, or SmCo Magnets are widely applied in aerospace domain, industrial and medical areas, defence and telecommunication fields. When compared with neodymium magnets , neodymium magnets are 100% more stronger on magnetism. For working temperature, Smco magnets can be applied in 250-350 ºC envionment while neodymium magnets under 240 ºC. Permanent Rare Earth SmCo Tube Magnets, SmCo Disc Round Permanent Magnet
We have produced this grade of material for use in DD PMG’s (Direct Drive Permanent Magnet Generators) for small and large size wind turbines from 25 kW to 2.3 MW. DD PMG’s used in wind turbines offer the advantages of reduced size, weight and manufacturing costs of the generator without compromising efficiency. Reducing the footprint along with mass of the generator can, in turn, reduce the size and weight of other wind turbine components and hence the overall manufacturing cost. Over time, with fewer components, DD PMG wind turbines are also less likely to experience generator malfunction, gearbox failure, costly repair and lost productivity.
The bread loaf-shape magnet can effectively reduce torque ripple. However, at the same time the average torque is also reduced due to lower fundamental harmonics, especially compared to tile-shape magnet. However, by injecting 3rd harmonics, or even higher harmonics, not only the torque ripple can be reduced, but also the average torque can be aligned with the tile-shape magnet, or even be higher.
But once again, the shaping of magnet can be costly as well. Sometimes with bad processing methods, such as over grinding or over polishing, the cost can be even higher than skew. Therefore, in order to make the magnet shaping techniques commercially viable, it is really important to find easy ways to shape magnets.
Fortunately, we found some promising techniques that can easily enable magnet shaping. More interesting is that these techniques seem to coincide with a magnet recycling concept. The first method is using segmented magnets. A breadloaf shape magnet can be divided into several segments
