Efficiency​ of Variable Speed Screw Compressor

 

Efficiency is mainly decided by two parts of the air compressor. The first part is the host. It is easy for us to understand more air volume at cost of same power consumption means higher efficiency. The second part is electric motor. Permanent magnet motor and high efficient motor are common on current air compressors. Compared with ordinary electric motors, permanent magnet motors present higher efficient, higher power factor, and higher detent torch. Permanent magnet (synchronous) electric motors show the same detent torch as other synchronous electric motors. Without rotor windings, these permanent magnet motors show lower power consumption, because rotor excitation is unnecessary. However, permanent magnet motors need frequency converters which consume certain power. The test proves efficiency of low power permanent magnet motors remains higher than that of ordinary motors after adding frequency converters. We can use high efficient motors at high power stage to improve operation efficiency. On the other hand, characteristics of permanent magnet motors decide that they can maintain the same efficiency even at lower rotation speed. However, efficiency of ordinary motors declines with decreasing of rotation speed, showing a parabola curve
