For example: the scope of application of brushless dc motor, electric motor current brushless dc motor electric starting motorcycles starting motor and magneto are two independent motors, the engine structure is complex, overrunning clutch skid will seriously affect the starting characteristics of electric vehicles, starting motor through brush commutation, brush wear serious, requires constant maintenance. Brushless dc starting magneto is combined with magneto brushless dc motor starting, electronic commutation technology was applied to the starter motor, it saves reducer structure and transcendence is a converter, effectively simplifies the engine structure, improves the operation reliability, will become the mainstream of development in the future. Brushless dc motor, household appliances with air conditioner and refrigerator compressor motor, traditional compressor with motor usually for asynchronous motor, its frequency and power factor is lower, after adopting frequency conversion technology, the situation has improved. At the end of British dyson has no hakaze fan was born, the first paragraph marks brushless dc motor by the industrial application to intelligent home appliances infiltration. Nowadays, household cleaners, blenders, electric hair dryer, video cameras and electric fans and other electrical appliances are also gradually adopts brushless dc motor instead of the traditional single-phase asynchronous motor. Brushless dc motor can not only overcome the traditional household electrical part of the shortcomings, higher comfort brings to people's life that occupy the home, also can reduce energy loss, better realize the sustainability of energy. , medical apparatus and instruments with brushless dc motor 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 instrument with a drive motor is single-phase ac/dc series motor and voltage regulator, noise is very big. Because the brush and the presence of phase switcher, cannot be disinfected before the surgery, can affect the effect in the operation, need regular replacement of brush and machine maintenance. And the brushless dc motor is more than there is no hidden trouble, as the drive system, the low noise, wide speed range, small volume, light weight etc, is undoubtedly the best choice for medical equipment. , automotive brushless dc motor with the development of the car in the direction of energy saving and environmental protection, efficient, including dc brushless motor, permanent magnet motor has a good application prospect in the car. Motor 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. , industrial equipment, industrial application scenarios in brushless dc motor 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 dc motor.
