What Is The Demagnetization Standard For Small Motor Magnets?

The demagnetization standard for small motor magnets is generally no more than 5%. The following is a detailed explanation of this standard:

● Definition of Demagnetization: Demagnetization refers to the degree to which a magnet's magnetism weakens during use due to various reasons. It is usually expressed as a percentage of the magnet's initial magnetism.

● Demagnetization Standard: For small motors, if the demagnetization of a magnet exceeds 5%, motor performance will typically degrade significantly, or even become inoperable. This is because weakened magnetism directly impacts key motor performance indicators such as torque, speed, and efficiency.

● Impact Analysis: If the demagnetization of a small motor's magnet exceeds the standard, it may lead to problems such as difficulty starting the motor, unstable operation, and reduced efficiency. In severe cases, the motor may even fail to start or operate abnormally, impacting the normal operation of the entire equipment.

Therefore, during the design, manufacture, and use of small motors, strict control of the magnet's demagnetization must be ensured to remain within the standard range to ensure motor performance and reliability.
