How to remove electric vehicle motor magnets?

1. Motor magnets can be easily removed by heating. Simply heat the magnet with fire until the temperature reaches a certain level, loosening it from its fixed structure and facilitating disassembly.

2. Motor magnets are primarily made of permanent magnet materials, including neodymium iron boron (NdFeB) magnets, samarium cobalt (SmCo) magnets, and alnico (AlNiCo) magnets. NdFeB magnets come in two types: sintered NdFeB and bonded NdFeB. Sintered NdFeB magnets are commonly used in motors. These magnets possess extremely high magnetic properties, capable of attracting objects up to 640 times their own weight. Due to their exceptional magnetic properties, they are known as the "King of Magnets." NdFeB magnets are particularly common in motors.

3. Samarium cobalt (SmCo) magnets are typically only available in sintered form. Their properties include high-temperature resistance, oxidation resistance, and corrosion resistance, making them suitable for high-temperature environments or specialized applications such as aviation. These properties make SmCo magnets commonly used in high-temperature motors and aviation products.

4. Alnico magnets are relatively rarely used in motors, primarily because their magnetic properties are lower than those of other magnets. However, in applications requiring high-temperature resistance above 350°C, Alnico magnets are an essential material choice.
