Permanent Magent VSD Screw Air Compreessor

Permanent magnet variable frequency screw compressors can maintain high output efficiency at low rotate speed. The greater the fluctuation of air volume in the system, the more obvious energy saving effect is. LGM series permanent magnet frequency conversion screw air compressors adopt permanent magnet (IPM) motor with huge energy saving efficiency and superior performance. When used with dedicated servo drivers together, they will give full play to the incomparably energy-saving effect than general induction motors. According to the exhaust temperature, cooling fan with variable frequency control can control the fan rotate speed to prevent power waste, reduce noise and stabilize the system. Through wide range control, the maximum amount of air displacement is increased by about 16%.
