  • Product Description
Introduction of permanent magnet synchronizing Variable frequency Screw Compressor
The permanent magnet synchronizing variable frequency compressor is a most recent compressor with excellent quality and high efficiency and energy saving at present. It is an advanced technique owned by only a few advanced countries and zones in the world.It is a high-end tendency for the future compressor development.The design concept and technical measure has broken through the traditional technical concept.It integrates the most sophisticated and energy saving technical factors.

Excellent quality of motors
The permanent magnet synchronizing variable frequency compressor is equipped with high efficiency permanent magnet synchronizing motor(PM motor).compared to normal motors,PM motor has smaller volume and more excellent energy saving.It with exert incomparable energy saving effect than normal inductive motor when installed with the special frequency converter . It uses high performance NdFeB magnets which will not loss magnet even at 120 ℃ and the service life can be up to 15 years .the service life can be up to 15 years.the stator winding can be of special corona resistant wire for frequency converter with excellent insulation performance.As the magnetic conductivity of rotors is very high,the diameter is very small and able to be installed at the extending shaft of the male rotor,without use of bearing,thus eliminating the faults of motor bearing and improving the driving efficiency.

Significant energy saving effect

permanent magnet synchronous variable frequency air compressor is always running in the load state without unloading operation, so there is no waste of power. The efficiency of permanent magnet synchronous motor is very high. Compared with the ordinary motor, the efficiency is improved by at least 2%, and the output torque is greater with less energy consumption. The energy saving effect is remarkable, and the energy consumption is maintained at the most economic level。

Excellent quality of motors
The permanent magnet synchronizing variable frequency compressor is equipped with special frequency convertor with wider frequency converting range.with the rapid development of techniques,the variable frequency compressor has become a high-grade machine in the energy saving area.It can realize maximum energy saving effect with the permanent magnet synchronizing motor.
