Permanent magnets are magnetic materials that maintain a persistent magnetic field without external power, used in vibration motor cores to generate consistent magnetic forces for mechanical vibration.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Coating | Nickel, epoxy, or zinc for corrosion resistance | |
| Coercivity | ≥ 10 kOe for high-grade magnets | |
| Dimensions | Customizable (e.g., 10mm diameter x 3mm thickness) | |
| Magnetic Strength | Up to 1.4 Tesla for neodymium magnets | |
| Operating Temperature | -40°C to 150°C |

Permanent magnets offer energy efficiency by eliminating the need for continuous power to maintain magnetic fields, provide consistent performance with high magnetic strength, and enable compact motor designs due to their high energy density.
Temperature increases can reduce magnetic strength (reversible losses) or cause irreversible demagnetization if exceeding the material's Curie temperature. Proper material selection and thermal management are crucial for stable operation.
