Sintered neodymium iron boron and samarium cobalt permanent magnetic materials belong to rare earth permanent magnets. The prices of their main raw materials, praseodymium-neodymium, samarium and cobalt, fluctuate greatly.
In the NDFEB magnet formula, In the formula of neodymium iron boron, there are approximately 65% iron, 32% rare earth, 1% boron, and about 2% other elements.
Magnets with a 35EH rating refer to a specific classification within the NdFeB magnet series, characterized by their high maximum operating temperature and excellent temperature stability.
The applications of SmCo magent and NdFeB magent, two distinct types of rare earth permanent magnets, vary due to their unique properties.
Designing the magnetic circuit of a permanent magnet motor is a complex process, and multiple factors need to be considered to ensure the performance and efficiency of the magnetic circuit. The following are the general steps and factors to consider when designing the magnetic circuit of a permanent magnet motor:
