SmCo magnet and neodymium magnet are both belong to the powerful magnet. The difference between them is the samarium-cobalt magnet belong to high temperature resistant magnet. It has good temperature resistance and stable temperature resistance.Samarium cobalt is the best magnetic material in addition to ferrite on temperature resistance effect!

But for neodymium magnet, the magnetic force is generally better than samarium-cobalt!

Since the samarium-cobalt magnet has a lower magnetic density than that of the neodymium-iron-boron magnet, the air gap magnetic field strength necessary for the energy conversion is not as high as that of the neodymium-iron-boron magnet, so the capacity of the permanent magnet motor is smaller. After the introduction of NdFeB Permanent magnets, the situation has undergone major changes. The magnetic field generated by the high-performance NdFeB Magnet not only achieves the magnetic field strength generated by current excitation, but also far exceeds the current excitation, so that large and medium-sized motors of thousands of kW can be manufactured. But it is important to underline that 95-98% of magnets in electric car industry are nowadays associated with Nd, rather than Smco magnets. The situation is changing, and in fact, SmCo magnets are becoming the first choice for some high-tech applications.
