In the application of screw air compressor, whether to consider four issues: screw air compressor speed, screw air compressor working temperature, screw air compressor smoothness, screw air compressor operating environment.

Compared with the general variable frequency motor, the permanent magnet air compressor has better energy-saving function.

1. The permanent magnet synchronous motor uses high-performance NdFeB permanent magnets, which will not lose magnetism at 120 °C;

2. The stator coil is made of corona-resistant enameled wire specially designed for inverter, which has excellent insulation function and long service life;

3. Synchronous motor response speed is fast, exhaust response speed is high;

4. A soft start can be achieved. During operation, the motor current will not exceed the full load current, the impact on the grid equipment will be greatly reduced, and it will not cause harm to the electrical equipment.
