Electrical engineering certainly son united at heart degree(lack of impartiality<5 silks), turn son,move,the quiet balance(do not need to increase or decrease the auto balance, the electric field,magnetic field,the dint field all broke) reach EU standard(vibration<1.5),the match cleft<30 silks, the whole machine vibration is small in 0.9, the 噪 voice<60 decibels, the efficiency promotes 5%, the power raises 5%.
Electrical machinery stator concentricity (partial <5 silks), rotor, moving, quiet equilibrium (avoid increasing and decreasing autobalance, electric field, magnetic field, force field have not been destroyed), up to European Union's standard ' shake <1.5), cooperate with the interval <30 silks, the complete machine is shaken and smaller than 0.9, the noise <60 decibels, efficiency promotes 5%, the power is improved by 5%.
