1. The power factor is advanced. The general rated power factor is 0.9. It is helpful to improve the power factor of the power grid. Increase the power grid capacity.
2. High operating stability. When the grid voltage suddenly drops to 80% of rated value, its excitation system can generally be automatically adjusted to implement forced excitation to ensure the stable operation of the motor.
3. The overload capacity is greater than that of the corresponding asynchronous motor.
4. High operating efficiency, especially low-speed asynchronous motors.
