The Permanent-Magnet Synchronous Motor (PMSM) excels in high efficiency, a strong power factor, and superb performance, making it ideal for use in electric vehicles, wind power generation, and efficient motors. With an efficiency surpassing the IE4 level at 87.08%, the PMSM effectively converts most input energy into mechanical energy without requiring a variable frequency drive. Its primary feature is its ability to generate a constant magnetic field, synchronously rotating with the rotor, thus negating the need for extra power.
