The coil matching of the motor usually depends on a number of factors, including the design needs of the motor, the required performance, working conditions, etc. In a motor, the level of the magnetic steel and the coil must match each other to ensure the performance and efficiency of the motor.
Usually, the level of the coil should match or be slightly higher than the level of the magnetic steel. If the level of the coil is too low, the motor may not be able to fully utilize the performance of the magnetic steel, leading to a decrease in efficiency. However, the level of the coil should not be too high, as this may cause overheating of the coil and motor damage.
Traditional matching method between magnetic steel and coil:
Traditionally, people tend to choose coils with similar grades to magnetic steel to ensure maximum conversion of magnetic energy. For example, grade 8 magnetic steel is usually paired with coils of grades 7-9. This pairing method can meet basic needs to a certain extent, but whether it can achieve the best effect still needs further research.

Matching across grades: Consider combinations of different grades of magnets and coils. We can experiment with higher or lower grade coils to explore their potential performance advantages. For example, the combination of an 8-grade magnet with a 6-grade coil may bring unexpected results, resulting in higher efficiency and smaller size.
Mixed material matching: In addition to magnets and coils, we can also introduce other materials to optimize the matching scheme. For example, pairing a magnet with a special conductor material may change the current distribution in the coil, thus improving energy transfer efficiency.
New Design Ideas: Abandon traditional matching methods and adopt innovative design ideas. Through in-depth understanding of electromagnetic field distribution, magnetic flux density and other aspects, we can rethink the problem of matching magnets and coils and propose new solutions.
When choosing a coil level, you need to consider the following factors:
1. Magnet level: First, understand the level of magnets used in the motor, and then choose a coil level that matches or is slightly higher.
2. Operating conditions: Consider the motor's performance needs under different operating conditions, such as load, speed, temperature, etc.
3. Efficiency and performance: Ensure that the coil grade provides the required motor performance and efficiency.
4. Heat and Loss: Avoid choosing too high a level of coil, which may lead to additional heat and loss.
It should be noted that motor design is a complex engineering task that usually requires engineers to perform exhaustive calculations and analysis. Therefore, it is best to consult a professional motor designer or engineer to ensure that the motor's magnet and coil levels are correctly matched to meet the needs of a particular application.
