Skewed-rotor structure and manufacturing process.
Background technology
Calculate according to statistics, about 1,700,000,000 kilowatts of China motor recoverable amount, the kilowatt hour of total power consumption about 3,000,000,000,000 accounts for the whole society total
The motor total electricity consumption of the 64% of power consumption, wherein industrial circle is 2.6 trillion kilowatt hours, accounts for the 75% of commercial power, country
In propulsion energy-saving emission reduction, organizing and implementing " ten big energy conservation projects ", energy-saving of motor system engineering is listed in wherein, it is first in implementation
Standard platform construction is first advanced, makes the energy efficiency market of China's small and middle induction motors and efficiency grade to international electromechanics trade
Standards system is drawn close, and in GB18613-2012 standards, 2 grades of efficiency is confirmed to be high efficiency motor, is marked equivalent to IEC60034-30
IE3 grades in standard, 1 grade than GB18613-2006 standard upgrading.
State Administration for Quality Supervision and Inspection and Quarantine, Standardization Administration of China were on June 29th, 2012 immediately
Issue, on November 1st, 2012 implement GB/T28575-2012《YE3 series（1P55）Ultra-High Efficiency threephase asynchronous technology
Condition（Seat No. 80-355）》, efficiency value specified in this document is identical with 2 grades of energy efficiency markets in GB18613-2012.
So, newly-designed motor will reach 2 grades of efficiencies of GB18613-2012 standards and GB/T28575-2012 standards
Specified in energy efficiency market just have certain difficulty, therefore, when YE3 series is designed, designing technique, manufacturing process and material
The aspects such as material cost are greatly improved, in addition it is also necessary to by adjusting core material and flute profile size, winding data come balance electric
Every loss of machine reaches efficient 2 grades with performance, even if so, according to IEC approved IE5 efficiency limit values, therewith, China
1 grade of efficiency of motor will also be lifted again, entire series to reach 1 grade of efficiency hardly possible.
