In 2017, each big BBS are reproduced hong-tao li's story about the brushless motor inventors. Speaking of hot li, everybody but call him the man of god, a man of science hot li invented all kinds of black science and technology,
hot li, male, born on August 12, 1966 in hubei province HuangBei County, was born in a common intellectual family. When he was 14, in the hot li earned to & other; Outstanding young & throughout; And won the second prize in the national high school mathematics competition's, is a typical man of science.
the brushless motor was invented which country? Who invented?
then was admitted to zhejiang university department of electronics in 1984, 1988 and married his girlfriend, but two years later, the affair is cheating. In 1992 for fraud by kunming municipal public security bureau detention. He with great ideas and brain, twice in a prison escape, and outside to crime.
hot li once 3. Owe because too clever to police's uncle hold the escape from prison after open pu police cars running around but already been sentenced to death in prison by science knowledge invented a patent for invention exposition gold medal, so successful online scrounge a life from death, into a prison. He helped the prison prison break prevention system improved ultimately successful start another Duan Sheng tongue with facts proved that learn English well everywhere.
in the escape, the only thing that can make hot li full penetration of the Lord is god invented & other; Brushless motor & throughout; The idea of. He learn radio, machinery with unusual interest. The day before the death penalty, hot li victory over death successfully developed brushless motor, hot li also change to a suspended death penalty. Invented in 1995, hot li & otherElectrical excitation brushless motor & throughout; For the fifth China patent invention exposition gold medal won the first prize in yunnan province outstanding inventions. The hot li when applying for patent aliases for & other; Yang Hongjun & throughout; 。 Subsequent years hot li (Alias & other; Yang Hongjun & throughout; ）And a number of inventions, won three invention patent, utility model patent. Due to significant hot li meritorious service, comply with legal sentence and sentence, suspended prison instead. Born in 2009, hot li released to begin a new tongue.
brushless motor in China is actually in such a legendary story of the birth of as the father of the brushless motor, hot li make China's success began to shift to the brushless motor from the brush. So what is the advantage in competing brushless motor can make a death sentence, or even a new lease on life.
brushless motor advantages: high efficiency, low energy consumption, low noise, long life, high reliability, servo control, stepless frequency control of motor speed, relatively low cost and easy to use. Brushless dc motor without the use of mechanical brush device, using square wave self-control type permanent magnet synchronous motor, with hall sensor to replace carbon brush and commutator rotor in ndfeb permanent magnet materials, the performance has great advantages, compared with the general traditional dc motor speed regulating motor is the most ideal. Its speed control system than the cost of a brush, speed control system of high-speed motor, controller in use are prone to failure. Electric bicycle with brushless motor speed must be to more than 35 km/h, can play the best efficiency, but we know that electric bicycle as a non-motor vehicle management, speed must be under 20 km/hour, so the brushless motor is electric bicycle is chosen to reduce the working efficiency, desirability is not strong. Now it is used in the main point is the noise is small. Brushless motor is to use electronic circuit commutation! Have polarity detection element!
no brush, low interference. In addition to the brushless motor brush, the most immediate change is without the motor running when the electric spark, thus greatly reduce the electric spark interference of remote radio equipment. low noise, smooth operation. Brushless motor without brush, less friction force during operation, smooth running, low noise will many of the advantages of model running stability is a huge support. long life, low maintenance cost. Wear little brush, brushless motor is mainly on the bearing, from the mechanical point of view, brushless motor is almost a maintenance-free motor, when necessary, the only need to do some cleaning maintenance. brushless motor in our country, the development of the time is short, but as the technology increasingly mature and perfect got rapid development. Has been used in model aircraft, medical equipment, household appliances, electric cars, and other fields is widely used, and in shenzhen, changsha, Shanghai and other places to form certain scale industrial chain. Three association, such as shenzhen, HDB han debao professional manufacturers such as electrical, constantly promote the industry development in technology. brushless motor inventor hot li, invention of brushless motor, and promoted the rapid development of motor industry in China, it also makes the industry always remember him, also known as & other; The father of the brushless motor & throughout; 。
