The permanent magnet synchronizing variable frequency compressor is equipped with high efficiency permanent magnet synchronizing motor (PM motor). Compared to normal motors, the PM motor has a smaller volume and more excellent energy saving. It will exert an incomparable energy-saving effect than a normal inductive motor when installed with the special frequency converters.
It uses high-performance NdFeB magnets which will not lose magnets even at 120℃ and service life can be up to 15 years. The stator winding can be of special corona resistant wire for frequency converters with excellent insulation performance. As the magnet 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 the use of bearing, thus eliminating the faults of motor bearing and improving the driving efficiency.
