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.
Choosing the right magnet for a permanent magnet (PM) motor is critical for optimizing performance, efficiency, and cost.
When purchasing magnets, several aspects need to be taken care of to ensure that the magnets purchased meet the specific application needs and quality standards. Here are some key considerations:
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:
