1. High power factor.
2. High starting torque.
3. Good performance indicators.
4. The efficiency and power factor of permanent magnet synchronous motors decrease very little. When the motor has only 20% load, its force energy index is still above 80% of full load.
5. When the Y series motor operates at 60% load, the efficiency decreases by 15%, the power factor decreases by 30%, and the force and energy index decreases by 40%; However, the efficiency and power factor of permanent magnet synchronous motors decrease very little. When the motor has only 20% load, its force energy index is still above 80% of full load.
6. Low temperature rise: There is no resistance loss in the rotor winding and almost no reactive current in the stator winding, resulting in low motor temperature rise.
7. Small size, light weight, and low consumables: The volume, weight, and materials used for permanent magnet synchronous motors of the same capacity can be reduced by about 30%.
8. Capable of atmospheric gap formation, facilitating the formation of new magnetic circuits.
9. The armature has a small reaction and strong overload resistance.
