Power consumption in the whole society, there are about 70% cost in the field of industry, and industrial electrical power consumption and occupy 70% of all industrial electricity. In retrofit of industrial motor, therefore, can greatly reduce the energy consumption of the whole society. Calculated according to 30% of the energy saving effect, if the energy saving renovation of all industrial motor, power consumption will fall by 15% a year, in the whole society has a great economic and social benefits. It can be seen that the motor energy saving potential is tremendous, improving the efficiency of the motor will be the primary method of industrial energy saving. Improving the efficiency of the motor can be mainly through two ways, one is by frequency converter speed control, improve the operation efficiency of ac motor; The second is using efficient motor. Depend on the frequency converter is the main way in the field of industrial energy saving, energy saving of frequency converter efficiency generally over 30%, in some industries and even reached 40%50%. The proportion is still low efficient motor market application, but with minimum energy efficiency standards and subsidy policy support, the future market application of efficient motor proportion will rise sharply. Broad prospects for energy conservation and environmental protection industry development in the future, by 2012 the total output value will reach 2. 8 trillion yuan, in 2020, will be more than 5 trillion yuan, to become one of the important pillar industry of national economy. Energy conservation and environmental protection, energy conservation refers to industrial energy saving and building energy conservation, environmental protection is mainly wastewater treatment, solid waste treatment, desulfurization denitration dust removal, etc. On investment, should be in the policy of good layout, before it has a niche industry leading investment opportunities. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
