Brushless motor in China is actually in such a legendary story was born 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's the advantage of brushless motor can make a death sentence, or even a new lease on life.
the condemned to die before the invention of brushless motor, not only saving the death penalty, are now become a well-known scientist
talking about hot li, everybody but call him the man of god, because is too clever to police's uncle can't catch, drive the police car running around after prison break, but already been sentenced to death in prison by math, science knowledge, invention patent, the invention exposition gold medal, so successful online scrounge a life from death, into a prison.

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.

in 1995, invented by hot li & other; Electrical 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. In 2009, hot li released, start a new life.

hong-tao li's life is very legend, his invention to today is very hot, posters or sales, will be electric tools is brushless motor as a big selling point, if you ask what is the difference between, many people only know the difference between is the presence of carbon brush, so what is the carbon brush, it has what effect, have the difference between the motor and the brushless motor?

carbon brush people also called it brush, mainly on the electrical equipment widely used, is in some kind of motor or generator fixed part and the rotating part do signals or energy transfer, shape is a rectangle, and metal wire installed inside a spring, carbon brush is a kind of sliding contact, so easy to wear need to be replaced regularly and clean up the wear of carbon.

the main components of the carbon brush is carbon, working through the spring pressure is like a brush on the piece of work, it is called a carbon brush, the main material is graphite.
to know about the major materials of graphite, carbon brush, graphite belongs to the natural elements, its main component is carbon, color is black, opaque, with metallic luster, hardness is not high, can pull the with her nails, composition of graphite and diamond are carbon, but there is a big difference in the nature, this is caused by the arrangement structure of different carbon atoms.
although graphite composition of carbon, but it is a kind of high temperature resistant material, its melting point 3652 ℃, using the characteristics of the high temperature resistant, graphite can be processed into high temperature resistant chemical apparatus crucible.
graphite conductive performance is very good, more than a lot of metal, nonmetal is one hundred times, so manufacturing electrode, carbon brush, such as conductive components. The internal structure of graphite determines its good lubricity, we often in the rusty door lock into the ash or graphite pencil and open the door would be easier, so it should be the lubrication effect from graphite.

do not think that graphite pencil lead can only do these products, now the new material graphene from graphite, you must have heard of, it has become the hottest new technology materials, now it is necessary for a lot of high-tech products.

carbon brush generally used on dc electrical appliances, like we use in the home refrigerator, washing machine and air conditioning, no brush, this is because the ac motor don't need constant magnetic field, so there is no need for the commutator, no carbon brush.
to understand the function and significance of the carbon brush, must first understand the motor and the working principle of the brushless motor and difference. brushless motor manufacturers
