Technical features

The 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 reaches or exceeds the first-class standard of GB30253-2013 “Energy Efficiency Limits and Energy Efficiency Grades of Permanent Magnet Synchronous 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 pump loads;

2) It can be designed with high starting torque and high overload capacity,

3) The high-efficiency operation range is wide. When the load rate is 25%-120%, the operating efficiency and power factor do not change much, and the operating efficiency is >85%, and 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, and the capacity of substation equipment can be fully utilized.

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

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

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