With the development of China's industrial economy of the motor, the motor has been widely used. According to statistics, the electrical system power consumption accounts for about 60% of the national electricity consumption, which accounts for 10.4% fan power consumption of the country, accounting for 20.9% of pump motor variable frequency motor, compressor 9.4%. However, our electrical products for more than 80% of the low efficiency of 2% -5% higher than the international advanced level, the motor system efficiency of 10% -20% lower than the advanced level. Therefore, China has a huge demand in the motor system to improve efficiency and strengthen aspects of energy management systems. Refers to the effective and efficient motor output power and input power is relatively high motor, mainly for efficiency motors. Motor in converting electrical energy into mechanical energy, while part of the energy loss itself, these losses include winding losses, core losses, stray wind mill loss and load loss. Motor and the motor efficiency as compared to ordinary, in converting electrical energy into mechanical energy in the energy conversion process has a higher energy conversion efficiency and lower energy loss. Countries in the world have developed motor energy efficiency standards, according to the US National Electrical Manufacturers Association standards (NEMA standard), high efficiency motors increased by 2% to 6% higher than the standard motor efficiency, ultra-efficient motors more efficient than "NEMA Standards" Motor 0.8% -4%. The nature of high-efficiency motors to achieve "efficiency" is to reduce the internal motor of energy loss, the total loss of the motor efficiency is lower than General Motors 20% -30% YE2 efficient motors, high efficiency 2% -7%. Promotion of efficient motors help reduce motor losses and improve motor efficiency. Improve the efficiency of the motor in the motor system energy is a very important part. Y series motor efficiency is widely used in China's current average of 87.3% YE3 for energy-saving motors, while the average of YE2 efficient motor efficiency was 90.3% with an average efficiency of YE3 products in recent years, the introduction of ultra-efficient electric motor as much as 91.7%. Obviously, the motor efficiency is achieved by increasing the energy savings potential of a huge object. Efficiency motors mainly in the manufacturing process improvements in the following areas:? Electromagnetic optimization design, round system, gap, groove engagement, and fully optimized geometries, and through a lot of prototype testing repeated verification, the electromagnetic design guarantee for the motor to achieve the best performance. ? Silicon steel core made of high quality low iron loss, high permeability, and magnet wire using temperature rating to Class H (180 ℃) Polyester enamelled round copper QZY-2/180, greatly improve the performance of the motor, lower operating temperature and loss, so as to improve motor efficiency. ? Improved motor bearing system, optimizing the shape and fan, hood designed to reduce mechanical losses in the motor. ? Using the latest VPI vacuum impregnation process makes the anti-voltage impulse to strengthen capacity of the entire coil, reducing the white insulation between turns and accident rates; protection and insulation levels than older motors at least raise a grade.
