In recent years, our country small and medium-sized motor controller and micro &special motor controller industry development is rapid, the brushless dc motor controller, with its high efficiency low noise characteristics, a brush motor controller is gradually replace, become a new star of industry applications. This, in China's leading outsourcing service platform has a more prominent reflect fast. It is reported, in a package of 100 + motor controller control task, brushless motor controller with 78% accounted for more than a near monopoly platform motor controller to control demand. The following, the author with some cases, analytical current brushless dc motor controller for the reader some mainstream application scenario. Mainstream application scenario 1: industrial equipment with brushless dc motor controller industrial application scenario precision, efficiency and performance of equipment and so on all have higher requirements. In some precise control of speed and position are mostly used in light industry machinery brushless motor. Such as fast package platform released 'motor controller control protection, condition monitoring task is applied in the industrial feeding machine. Mainstream application scenario 2: automotive brushless dc motor controller with the development of the car in the direction of energy saving and environmental protection, including brushless dc motor controller, high efficiency permanent magnet motor controller has a good application prospect in the car. Motor controller besides can serve as the core component of automobile driving, also can be used in automobile air conditioning, airbags, wiper, electric door drive power seats, etc. The author understands from beside, quick package platform 'with hall sensor controller of dc motor control' case with the wiper drive in the car. Mainstream application scenario 3: medical instrument with brushless dc motor controller with the development of domestic medical technology level and people living standard rise, practicality and experience requirements for medical equipment is also increasingly stringent. Such as the need of orthopedic medical apparatus and instruments as a result of the surgery, can ask its power system in a wider scope of continuous variable speed, to adapt to the seam milling, drilling, sawing and other kinds of occasions. Existing orthopedic medical devices with a drive motor controller is single-phase ac/dc series motor controller and voltage regulator, the noise is very big. Mainstream application scenario 4: home appliance with brushless dc motor controller for air conditioner and refrigerator compressor motor controller, the traditional compressor motor controller for induction motor controller often, the frequency and power factor is lower, after adopting frequency conversion technology, the situation has improved. At the end of 2009, the British dyson has no hakaze fan was born, the first paragraph marks brushless dc motor controller by industrial application to intelligent home appliances penetration. Mainstream application scenario 5: brushless dc motor controller of electric vehicles. the current electric starting motorcycles starting motor controller and magneto controller is two separate motor controller, engine structure is complex, overrunning clutch skid will seriously affect the starting characteristics of electric vehicles, starting motor controller through brush commutation, brush wear serious, requires constant maintenance.
