Permanent magnet frequency screw air compressor more expensive than other air compressor? Worth buying?

Permanent magnet frequency screw air compressor more expensive than other air compressor? Worth buying? In permanent magnet frequency

and ordinary screw air compressor frequency conversion screw air compressor are frequency converter, what is the difference between them both? Why price so different? In fact, the main difference is the motor, the second is characteristic.

permanent magnet frequency screw air compressor

( A) Motor:

general inverter screw air compressor is equipped with traditional asynchronous excitation motor - — Cage rotor induction generator has simple structure, strong, especially suitable for high speed motor, but the large capacity asynchronous generator and synchronous generator run side by side or parallel operation, provided by the synchronous generator or power grid itself needs. Asynchronous generator excitation for reactive power, so for the grid type reactive load. 。

2。 Actually, permanent magnet frequency screw air compressor USES the rare earth permanent magnet motor. The utility model has simple structure, reliable operation, small volume, light weight, low loss, high efficiency, and the flexible and varied in shape and size of the machine. Therefore, it is widely used to cruise day, defense, industrial and agricultural production and daily life.

（ 2) What are some of the characteristics of a permanent magnet frequency screw air compressor?

1, although ordinary frequency screw air compressor has no impact on the air pressure stable, energy saving, auto dormancy, characteristics. But due to the use of ordinary motor, there is also a risk of motor cooling. Speed after falling, poor motor cooling effect, saving energy effect is good, the motor heat dissipation become a contradiction.

2。 Permanent magnet frequency screw air compressor machine has the characteristics of environmental protection and energy saving, adopts coaxial connection method, variable frequency soft start, small impact on the grid, unique design, low noise micro leakage since the processing function, maintenance is convenient. More regulated to reduce mechanical wear and tear, improve the service life, low noise, good sleep function, high efficiency and energy saving. The present invention has the advantages of energy saving, low noise, power saving rate is above 40%, compared with the existing frequency screw air compressor, power saving rate is high, the efficiency is higher. In the industry, we implement the 'power saving, save money, save worry' goal.

by the above illustration, prove permanent magnet inverter screw air compressor is better than ordinary frequency screw air compressor. The so-called 'below value, lower than the price'. If you have any requirements, please call our GeLinKeEr consulting for details.
