Direct Conclusion
Permanent magnets rely on fixed magnetization and are prone to demagnetization; variable-frequency resonance generates a stable, continuous alternating magnetic field for more consistent performance.
Judgment Criteria
- 01
Permanent magnet devices have a simple structure, but their magnetic field strength decays over time.
- 02
Variable frequency drive covers different water qualities and pipe diameters.
