What are the different application fields of SmCo and NdFeB?
The applications of SmCo magent and NdFeB magent, two distinct types of rare earth permanent magnets, vary due to their unique properties.
How to design the magnetic circuit？
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:
Do the missing corners of magnets have a big impact on the magnetic properties?
During the production process of magnets, it is inevitable that some corners or edges will be chipped, especially due to the brittle nature of the rare earth permanent magnet material itself. No matter how meticulous the processing is, some chipped corners will appear. So do the missing corners of these magnets have a big impact on the magnetic properties? Let’s discuss it together.
How to prevent demagnetization of permanent magnet motors
As for the reasons for motor demagnetization, firstly, the motor cooling fan is abnormal, causing the motor to be high temperature, and the motor is not equipped with a temperature protection device; in addition, the ambient temperature may be too high; and finally, the motor design may be unreasonable.
