Features of permanent magnet variable frequency air compressor:

1. The air pressure of the permanent magnet variable frequency air compressor is stable

Since the frequency conversion screw air compressor utilizes the stepless speed regulation characteristics of the frequency converter, it can be started slowly through the controller or the PID regulator inside the frequency converter; it can quickly adjust and respond to occasions with large gas fluctuations. Compared with the upper and lower limit switch control of power frequency operation, the air pressure stability is exponentially improved.

2. The permanent magnet variable frequency air compressor starts without impact

Since the frequency converter itself contains the function of a soft starter, the starting current is larger in 1 of the rated current. Within 2 times, the starting impact is less than that of the power frequency starting, generally more than 6 times of the rated current. This effect is not only detrimental to the grid, but also to the entire mechanical system.

3. Variable flow control of permanent magnet frequency conversion air compressor

The air compressor driven by the working frequency can only work in one displacement, and the variable frequency air compressor can work in a relatively wide range of displacement. The frequency converter adjusts the motor speed in real time according to the actual gas consumption to control the exhaust volume. When the gas consumption is low, the air compressor can also automatically sleep, which greatly reduces energy loss. An optimized control strategy can further improve the energy saving effect.

4. The AC power supply of the permanent magnet variable frequency air compressor has good voltage adaptability

Due to the overmodulation technology adopted by the frequency converter, when the AC power voltage is slightly low, it can still output enough torque to drive the motor; when the voltage is slightly high, the output voltage to the motor will not be too high. For self-generating applications, variable frequency drives can show their advantages. According to the motor VF in the energy-saving state, the frequency conversion air compressor works below the rated voltage), and the effect is obvious for the scene with low grid voltage.

5. Permanent magnet frequency conversion energy-saving air compressor has low noise. Most of the working conditions of the frequency conversion system are lower than the rated speed, which reduces the mechanical noise and wear of the main engine, and prolongs the maintenance and service life. If the fan is also driven by frequency conversion, it can significantly reduce the noise of the air compressor when it is working.

Summarize the shortcomings of permanent magnet variable frequency air compressors as follows:

1. Fear of demagnetization The motor used in the permanent magnet frequency conversion air compressor is a permanent magnet motor. The weakness of this kind of motor is that it is afraid of demagnetization. The magnetic steel determines demagnetization. The motor is in a high temperature state for a long time and is easy to demagnetize.

2. More troublesome maintenance Compared with ordinary compressors, the maintenance of permanent magnet inverters is relatively troublesome. During maintenance of the machine head, remove the motor before removing the machine head. It also requires the use of specialized tools (the rotor has a strong pull) and professional maintenance.

Product Introduction

The benefits of permanent magnet VSD screw air compressor:

The permanent magnet motors offer increased energy efficiency compared to conventional asynchronous motors. The efficiency of permanent magnet motor average increase by 5%-10%, so that it could save a large amount of electrical cost for the user. The permanent magnet motor also features a compact construct, less size, lightweight, and high reliability.

The air compressor uses permanent magnet frequency conversion technology, if the user does not need so much compressed gas, the inverter will reduce the speed of the motor, reduce the amount of gas produced, and save electricity costs.
