Among the industry power consumption, industry motor account for 70%. If we improve energy conservation in industry motors, the social annual power consumption will be reduced largely, that will bring enormous economic and social benefit to the mankind.
To improve operation efficiency of electric motors, the user can adopt frequency inverter, or buy high efficiency motors. The energy saving efficiency of VFD can reach at least 30%, and even 40-50% in certain industries. But under the implementation of minimum efficiency standard and subsidy policy from government, the high efficiency motor application will be increased gradually.
