The market situation

High efficient motor Y series ac asynchronous motor replacing JO2 motor basic models without

limit,thus,all used the occasion of ac asynchronous motor Y series can be used Replace the JO2 series motor.Yx series motor market potential is restricted by its capacity.In principle,below 90 kw ac asynchronous motor can by Yx series high efficient electricity Machines replaced.90 kw ac asynchronous motor installed capacity of the following accounts for about 30% of the total ac asynchronous motor.In recent ten years,the Chinese government is committed to promoting motor drive technology,all walks of life to www.dongfeng-motor.com some extent,the motor drive.According to the oil,electricity,building materials,steel Iron,non-ferrous,coal,chemical industry,paper making,textile and other departments recently sampling survey results of the enterprise,the petroleum chemical industry,building materials,motor drive application is better.In the current 400 million KW motor load,is about 50% of load change,30% of which can be to solve the problem of the load changes motor speed.So in the current market capacity,There are about 60 million kW of speed regulating motor market.All kinds of motor installed capacity in China has been more than 400 million kW,which accounted for about 90% of the asynchronous motor,accounted for about 80% of small and medium-sized motor,Drag the water pump centrifugal pump and fan about 130 million kW compressor motor of such a machine.At present,small and medium-sized motor has more than 152 series,842 varieties,more than 4000 specifications.In the last ten Over the years,industrial machinery,such as the relevant departments to grasp the energy-

saving work of the motor,organizational leadership institute and enterprises,has made a variety of energy-saving motor design,and Has issued out 63 energy-intensive motor and promotional 24 kinds of energy-saving motor,achieved some results.These energy saving products are mainly divided into two

categories: one kind is to improve the electricity Incentive efficiency of high efficiency

motor,another kind is adjustable speed motor.Dc motor using the octagonal laminated structure,not only high space utilization,and when using static rectifier power supply,can withstand the current ripple and fast load Current changes.General without motor fan series dc motor winding,is suitable

for the need of positive and reverse automatic control technology.According to user needs can also be made with series winding. High center 100 ~ 280 mm motor without compensation winding,but the center height of 250 mm,250 mm motor according to the specific circumstances and needs can be made into with compensating winding,high center 315 ~ 450 mm motor with the compensation winding.Center height of 500 ~ 710 mm motor installation appearance,size and technical requirements are in conformity with IEC international standard.
