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 improving the performance of the motor ye3 ultra-efficient motors, reduce operating temperature and loss of energy-saving projects that benefit high efficiency motor, 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. Energy efficient motors compared with ordinary motor, needs consume more copper, aluminum, cold rolled silicon steel and other raw materials, high production costs, with the specifications of energy efficient motors market price per kilowatt (excluding government subsidies) than the average motor higher than about 10% -30%. Currently, energy efficient motors are relatively expensive because of the purchase price, promotion started late and other reasons, a lower penetration rate in our country, and the effects of lower than expected. However, due to recent government formulated the "+ ban inefficient subsidies and efficient" dual policy on the promotion, production and sales of energy efficient motors which are growing. Energy-saving projects _ Dresdner Cheung motor efficiency motors (certified) _ Pakistan efficient motor is provided by Zhengzhou Dresdner Motor Manufacturing Co. Cheung. Zhengzhou Dresdner Cheung Motor Manufacturing Co. (www.deshengxiangmotor.com) (www.deshengxaingmotor.com) is Zhengzhou, asynchronous motor leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
