Permanent magnet synchronous motor provides the magnetic field required for electromechanical energy conversion by permanent magnets, without excitation power supply. There is almost no current in the rotor during synchronous operation, so the copper loss of the rotor is close to zero, and the power factor is greatly improved compared with the asynchronous motor. The reactive current in the stator winding is small, the copper loss of the stator is reduced, and the efficiency of the permanent magnet synchronous motor is higher than that of the asynchronous motor under the same conditions. The actual operating current of the permanent magnet synchronous motor is more than 15% lower than that of the asynchronous motor. The temperature rise is about 20K lower than that of a three-phase asynchronous motor with the same power and speed, and the power factor reaches 0.96 or above. The rated efficiency is 1% to 8% higher than that of the three-phase asynchronous motor, and the efficiency index Exceeds the efficiency value of the highest energy efficiency level 1 in GB18613-2020 "Energy Efficiency Limits and Energy Efficiency Levels of Electric Motors".

Permanent magnet synchronous motors also have significant advantages in other aspects:

1) Synchronous operation, no speed fluctuations, no increase in pipeline resistance when driving fans and pumps ;

2) It can be designed with high starting torque and high overload capacity, so as to solve the phenomenon of "big horse and small car" ;

3) The high-efficiency operating range is wide, and its operating efficiency and power factor are stable when the load rate is 25%-120% The change is small, and the operating efficiency is >85%, the power factor is >0.9, and the energy saving effect is remarkable.

4) The power factor is high, which improves the quality factor of the power grid. There is no need to install reactive power compensation devices in the power grid. The capacity of the substation equipment can be fully utilized.

5) Work with the frequency conversion speed regulation system, compared with the asynchronous motor, the dynamic response is better.

6) High power density, at the same power and speed, it can reduce at least one frame size compared with asynchronous motor .

7) There are many topological structures of permanent magnet synchronous motors, and customized products can be realized in a wide range and under extreme conditions Serve.
