Promotion of efficient motor outlook

Abstract:the motor is widely used in our daily life,it throughout all corners of the from all walks

of life,in the process of production,living plays a very important function.Promote efficient motor

can save energy,reduce pollution and broad prospects,but also promote efficient motor is faced with

difficulties.Key words:marketing;High efficiency motor;Prospects;difficult Devices of all kinds of

motor as a driving force,is widely used in industry,commerce,defense,utilities and other fields.The motor power consumption average accounts for more than 50% of the total power consumption of the world,accounting for more than 70% of the industrial electricity consumption.Research shows that

through the implementation of the motor efficiency standards and promote the application of high

efficiency motor,by 2011,accumulative total of 76.4 billion kW.h,save electricity,49.7 billion

yuan,CO2 emission reduction 7 6.4 million t (emission factor:1 kgCO2 / kW.h);By 2020,accumulative total of 1 65.3 billion kW.h,save electricity 7,80 billion yuan,CO2 emissions of 160 million t.China's the eleventh five-year plan clearly,energy consumption per unit GDP in 2010 than in 2005 dropped 20%,among them as a key project of one of the ten major energy conservation motor industry's goal is the average energy consumption by 20% ~ 30%.

Therefore,the improvement of motor efficiency is of great significance for China's current energy conservation and emissions reduction work.In this paper,the brief analysis of the promotion prospects of high efficient motor:A,the advantages of high efficiency motor determines its good promotion prospects:GB 18613-18613 "small and medium sized three-phase asynchronous motor limited value of energy efficiency and energy efficiency level" defined:reach level 3 indicators of energy efficiency for the common motor;To achieve the secondary indicators of energy efficiency (equivalent to the eu effl standard),as an energy-saving motor,namely

high efficiency motor;To reach the level of energy efficiency indicators for ultra high efficiency

motor.High efficiency and energy saving motor using new motor design,acmotortrading.blogspot.com new technology and new materials,by reducing the wastage of the electromagnetic energy,heat energy and mechanical energy,improve the output efficiency.Compared with the standard motor,motor using efficient energy-saving effect

asynchronous motor is very obvious,normally efficiency can be increased by 4% on

average.Efficient energy-saving motor mainly with ac frequency conversion motor,YX single

phase asynchronous motorefficient,Y3 low-voltage high-power,wind turbines,rare earth

permanent magnet motor,high voltage Y2 compact and YB2 flameproof motor,etc.

High efficiency motor has the following advantages:1,high efficiency and low loss.We know that the motor efficiency expression is:efficiency = (input power loss)/input power was 100%.By visible on type,improve the efficiency of motor is the key to minimize wear and tear (including,core loss and winding loss wind friction loss and stray loss).Excitation characteristic of high efficiency motor with good of senior electromagnet,generator rotor and stator small metal loss and increase the dosage of

iron core and copper loss is decreased obviously,improve the efficiency.YX series high efficiency motor in China than Y series motor with high efficiency by about 3%,basic Y series motor and J2,basic J02 compared series motor efficiency is 1% higher than the 1%.The energy saving effect of using efficient motor as shown.Promotion of efficient motor outlook Electrical specifications:fully enclosed external fan cooled,2,2 kw,4,200 v,50 hz rate:100% If run 1 year 5,000 hours,can power saving about 400 KWH.2,high reliability,long life and low noise.Due to reduced losses,reduce the motor running in the process of temperature,the cooling air volume reduction,effectively improve the reliability of insulation and bearing.High efficiency motor life expectancy is longer than the average life span for ordinary motor,and lower noise.3,keep the universality and interchangeability.Due to the installation size is the same as the standard motor,keep the universality and interchangeability.4,starting torque and high locked-rotor torque ratio,power rating.Due to the power level,to reduce user's installed capacity,can avoid or reduce the "big horse-drawn cart" unhealthy phenomenon.
