Dc motor & # 8203; Guide language in today's s power a lot of cost, the whole world is in advocate energy conservation and environmental protection, and mention energy saving, brushless dc motor is a great advantage, under the same power, it can reach a greater degree of energy saving. Ac motor and dc brushless dc motor with the captain at an organic whole, it has both ac motor structure brief, reliable operation, convenient maintenance and a series of advantages, but also has high power dc motor running, the function good characteristics of speed adjustment, brushless motor and other relatively high solid, high power and good speed regulating function and many other advantages. A brushless dc motor using category use category, category of test equipment. Brushless dc motor in the laboratory devices widely used, and useful device of motor required high precision, intelligent control, mainly use the centrifuge, mixer, etc. Laboratory electric mixer is liquid mixing solid-liquid mixture of test equipment, product design novel, the craft is advanced, the low speed torque output is big, have good use function. High power brushless dc motor drive, the numerical control knob type stepless speed; Safe operation condition, low noise, uninstalling a sensitive features such as simple. Is a scientific research institutions, universities and colleges, and medical units such as product development, quality control and production process used in the equipment. Use category ii, category of medical equipment. Abroad, for the use of brushless dc motor is all over, can be used to drive the small artificial heart blood pump; High-speed centrifuge at home, with high-speed operation equipment, thermal imaging and temperature measuring instrument of the infrared laser modulator are using brushless dc motor. Use category 3, working computer peripheral equipment, digital consumer goods category. This is the most widely in brushless dc motor, the largest category. Such as in the life of common printers, fax machines, photocopiers, hard drives, floppy drives, the motion picture camera, tape recorder, etc. , in their main shaft and auxiliary motor drive control, will find the figure of brushless dc motor. Four use category, category of industrial control. In recent years, due to the development of large-scale brushless dc motor and technology gradually, the size of its drive system in the industrial production distribution scale, has gradually become the mainstream of the development of industrial motor. Round down production cost and forward running power and open discussion with test has obtained remarkable benefits, each big manufacturer also supply different types of motors to meet the needs of different drive system. At this stage in the textile, metallurgy, printing, automatic production line, nc machine tools and other industrial produce, have dabbled in brushless dc motor. Use category 5, household electrical appliances category. “Frequency conversion & throughout; Technology has been very throughout, as a symbol of the Chinese electrical appliances gradually occupied most of the consumer market, & other; Dc frequency conversion & throughout; Produce by the manufacturer, has been gradually replace & other; Ac frequency conversion & throughout; The change of the trend. This change is essentially the motor by the induction motor used in the home appliance to the transition of brushless dc motor and its control device, to get to energy conservation and environmental protection, low noise, intelligent, high comfort requirements. The development direction of brushless dc motor and power electronics, control theory, sensor technology the development direction of the same, it is the combination of a variety of products, its development depends on the related each kind of technical innovation and progress.
