Application Scenarios And Precautions For Motor Magnets

Motor Magnets are key components in permanent magnet motors, primarily used to generate a constant magnetic field to drive the motor. They are typically made of high-performance permanent magnet materials (such as neodymium iron boron), offering high remanence, high coercivity, and excellent temperature stability.

Features and Processing:
Material: Common grades include N35SH, with an operating temperature of up to 150°C, a remanence (Br) of 1.18T, a coercivity (Hcj) of 20kOe, and a magnetic energy product (Hb) of 33-36MGOe.
Dimensions: Customizable upon request, for example, R8R3L2 (unit: mm).
Processing: Molded by sintering or bonding, requiring precision machining to ensure consistent magnetic properties.

Applications:
High-performance equipment such as servo motors, stepper motors, and wind turbines.
Industrial applications requiring high-temperature resistance or high dynamic response.

Precautions:
Installation: Avoid violent impact to prevent the magnetic tiles from breaking or demagnetizing.
Temperature Control: Long-term operation at excessive temperatures may cause magnetic properties to degrade.
Corrosion Protection: NdFeB magnets require a protective coating (such as nickel or zinc) to prevent oxidation.
