Features Of Permanent Magnet Variable Frequency Air Compressor
Ultra-low temperature rise design, the compressor allows long-term stable operation at ultra-low frequencies; closed-loop vector control system, faster control and more precise speed regulation; the compressor unit can still maintain efficient operation when the frequency is reduced by more than 50%; the pressure is stable, and the pressure is accurately controlled The fluctuation is within 0.01Mpa.
The figure shows the comparison of several starting methods. It can be seen that the inverter starts slowly and starts more smoothly, completely avoiding the current peak.
Under the set variable frequency pressure, the unit will automatically adjust to keep the output pressure within ±0.1bar, reducing unnecessary waste (for every pressure increase by 1 bar, power consumption increases by 7%)
Permanent Magnet Motors Have Advantages Over Common Asynchronous Motors
High efficiency: the loss of the excitation system is eliminated and the efficiency is improved.
High efficiency under low load conditions: The energy efficiency of permanent magnet motors is 9% higher than that of conventional asynchronous motors at full load, and as the speed decreases, their energy efficiency remains unchanged.
Large overdrive distance: the ratio of the maximum starting force to the nominal torque of the permanent magnet synchronous motor can reach more than 3 times, while the general asynchronous motor is only 1.6 times.
The control is more stable: the corresponding time of the permanent magnet motor is less than 50ms, and the gas production can be adjusted in a large range in an instant, so that the air pressure is truly stable.
