The advantages and disadvantages of permanent magnet variable frequency motors for air compressors, how do companies choose?

Advantages and Disadvantages of Permanent Magnet Inverter Air Compressors We are in the energy-saving era. No matter what kind of product we choose, we will take its energy-saving effect into account as a reference value for purchase. In the past two years, a new type of permanent magnet variable frequency air compressor has been released in the field of air compressors. This type of product has entered a higher level of energy saving with air compressors. It is currently the product with the best energy saving effect among all types.

Now in the new era of energy saving, the market for permanent magnet variable frequency air compressors is even bigger, and it is entering a new era of industrial energy saving.

After understanding the energy-saving advantages of the product, we should also grasp the shortcomings of the product. The following summarizes the shortcomings of the permanent magnet variable frequency air compressor:

Motor: The motor used in the permanent magnet variable frequency air compressor is a permanent magnet motor, and the weakness of this kind of motor is that it is afraid of demagnetization. The magnet steel determines the demagnetization. The motor is in a high temperature state for a long time, and it is prone to demagnetization.

Maintenance: Compared with ordinary compressors, the maintenance of permanent magnet frequency conversion models is relatively troublesome. During the maintenance process of the machine head, the motor must be disassembled before the machine head can be disassembled, and professional tools (the rotor has Strong attraction), requiring professionals to carry out maintenance work.

In addition to the advantages of energy saving, the following three advantages of permanent magnet variable frequency air compressors are summarized:

1. Low maintenance cost. It mentioned above that maintenance is troublesome. In fact, no matter what type of model it is, it is best to ask professionals to carry out maintenance work in accordance with the prescribed order. The maintenance cost of the permanent magnet frequency conversion machine is low, because it uses a high-efficiency energy-saving control system, which has little impact on the power grid and mechanical impact, and prolongs the service life of each part.

2. Low noise. Compared with ordinary compressors, the noise is low.

3. Reduce wear and tear. In addition to greatly reducing the power consumption, the air system is stable, which greatly reduces the loss during production.
