Dresdner Cheung motors widely used in construction, mining, food, hydraulic, medical, textile, printing, shearing, punching roll, matching motor power drill, small machine tools, fans and other mechanical equipment can be designed according to user requirements manufacture various types of special specifications, models of the motor. With a powerful, energy saving, reliable, overload features, is ideal for all types of machinery and equipment for power. Best-selling products, and supporting exports of Nepal, Italy, Pakistan, Russia and Southeast Asia and other countries. The companies adhering to the "technological innovation, GB manufacture, genuine, quality service," the purpose to meet all user needs. We sincerely welcome new and old customers, cooperation, agents, sales, support, export motor friction losses and flow losses: friction loss and flow loss in the past people did not get the attention it deserves, it accounted for about 25% of the total motor losses. Friction losses are mainly caused by bearings and seals, may be (1) to minimize the size of the motor shaft speed, but need to meet the output torque and rotor dynamics requirements; (2) the use of efficient bearings; (3) the use of efficient lubrication system and lubricants; (5) the use of advanced sealing technology, new seal usage reports if no spring, said by effectively reducing the contact pressure of the shaft, which allows the axis of rotation of 6000 rpm to 45mm diameter to reduce losses of nearly 50 W ; flow loss is the cooling fan and the rotor caused by ventilation slots for generating an air flow to cool the motor. Flow losses generally account for about 20% of the total motor losses. Fluid mechanics and heat transfer analysis of the entire motor is more complex than the space shuttle or the complexity of their components analysis, fluid dynamics and heat transfer, good design can significantly improve the cooling efficiency of the motor and reduce flow loss. Tapered motor, Dresdner Cheung motors (certified), the motor is provided by Zhengzhou Dresdner Yuxi Xiang Motor Manufacturing Company Limited. 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.
