Motor is a kind of using the interaction of electric and magnetic energy conversion and transmission of electromagnetic machinery, general motors including motor and generator. Motor absorb energy from the power system, the output mechanical energy to the mechanical system, various types of motors are widely used in the national economy departments as well as household appliances, mainly as a drive all kinds of mechanical equipment; Generator from mechanical energy absorption of mechanical system, the output power to the electrical system, plant protection unmanned aerial vehicle (uav) power system, generator and other related equipment technical progress, make people can use the heat energy, hydropower, nuclear energy, and energy such as wind, solar, biomass power generation, to the national economy departments and the broad masses of urban and rural residents to provide the necessary power.
the motor industry in our country after years of development, has formed a certain industrial foundation and industry structure, and has achieved a certain scale of production, industry entry barriers have significantly higher than a previous day. In 2016, according to figures from the National Bureau of Statistics, the motor manufacturing industry enterprises in our country the number to 2849.

in the motor industry, most of the ac motor dominated production. The specific data, 2008 -2016, the ac motor output growth is affected by macroeconomic fluctuations are more obvious. Ac motor production in China, 2016 to 2. 7. 8 billion kilowatts, fell 1. 7%.

brushless motor is the motor industry & otherNew & throughout; , into the country's history is not long, and high prices have a brush motor, brushless motor, but as a result of brushless motor obvious advantages, rapid development momentum. After entering China, quickly by household appliances, automobiles, ships and machinery and other industries preferred, and a place in the various industries, the rapid development. According to the National Bureau of Statistics, since 2010, brushless motor industry revenues in successive years increases, 2016 in 189. 200 million yuan, rose 22. 3%.

with the improvement of people's living standard and the development of modern production, office automation, household appliances, industrial robots and other equipment are more and more tend to high efficiency and miniaturization, high intelligence, as an important part of actuators, the motor must have a high precision, high speed, high efficiency, etc, the application of brushless dc motor and rapid growth. At this stage, though various types of ac motor and dc motor in the drive application dominate, but brushless dc motor is widely attention. In the next few years, our country the market prospect of the brushless dc motor is more optimistic.
