The permanent magnet motor is made by rare earth NdFeb permanent magnet material, and it is powered by permanent magnet special inverter. It has the characteristics of large starting torque, wide range of speed regulation, compact structure, small volume, light weight, low noise, high power factor and high efficiency, etc., which is the ideal choice of high -efficiency energy -saving air compressor.
The permanent magnet screw air compressor can effectively solve the gas waste of ordinary air compressors. According to relevant data, nearly 20% to 40% of gas is wasted during the use cycle of the air compressor. At the time of the start -up, the current can reach 2 to 3 times the rated current, which has a large impact. The motor of the traditional air compressor itself cannot achieve a speed reduction according to the changes in pressure demand, so that the output power of the motor does not match the actual pressure demand on the scene, resulting in empty -load operation when the amount of gas is used is small, resulting in a large electrical energy energy waste. The gas volume cannot maintain constant pressure, the use of accuracy does not meet the process requirements, which will affect production efficiency and product quality. The permanent magnet variable frequency screw air compressor is added with VFD, which can meet the real -time gas volume according to the gas volume conversion speed of different times at different times. Perfectly solve the problem of gas waste, has the characteristics of ultra -high energy efficiency, compact structure, low noise, small volume and other characteristics.
The permanent magnet synchronous motor can maintain the magnetic field without external energy, and the power saving effect is better than that of ordinary motors. The permanent magnet magnetic pole is installed on the rotor of the permanent magnet synchronous motor, which can maintain its magnetic field without external energy; the ordinary motor needs to be power -on to generate a magnetic field. Therefore, permanent magnet synchronous motor saves power than ordinary motors. The permanent magnet screw air compressor is generally equipped with the VFD of the power supply to change the power supply of the motor. The power supply voltage is provided according to the actual needs of the motor. Compared with ordinary screw air compressors, it has higher efficiency in terms of power use. The permanent magnet variable frequency screw air compressor combines the permanent magnet motor and the frequency conversion (VFD) system, so that the energy -saving effect of the two technologies can be played more effectively, and the average power of the permanent magnet variable frequency screw air compressor can save 30%~ 50%.
