Brushless DC motorconsists of the motor main body and drive; it is a typical Techtronic product. Brushless motor is point to brushless and commutator-free (or slip rings) motor, also known as non-commutator motor. As early as the birth of motor in the last century, the practical motor originate is brushless motor, also named AC squirrel cageinduction motor, motor has been widely used. In Mid-century, the transistor was born, and thus to the circuit instead of using transistors for DC brush and brushless motor commutator came into being. The new electronically commutated brushless motor was called as direct current motor, which overcome the defects of the first generation of brushless motors.
Practical new brushless motor are closely linked with the development of electronic technology, microelectronics, digital technology, automatic control technology and materials science. It is not only limited to the DC area, but also involved in electric, power generation, energy conversion and signal sensing and other fields.

DC Motor adopts octagonal full-laminated structure, it not only highly utilize the space, but also can withstand the pulsating current and fast load current changes when use the static power converter. Generally, DC motors without series excitation windings; they are suitable for the automatic control technology that needs to turn by positive and negative electric motor, They Can also be made to winding according to user needs. The motor with Center height from 100 ~ 280mm without compensation windings, But the center height 250mm, 280mm motors can be made with a compensation winding according to the specific circumstances and needs, Center height 500 ~ 710mm DIMENSIONS motor and technical are required in line with IEC international standards, motor mechanical dimensional tolerances meet the ISO international standards.
Among all motor, the most widely used category is AC induction motor (also known as theinduction motor) and dc brush motor,they are easy to operate.
 

 In the brushless motor, the original use of mechanical brush conversion is replaced by electronically controlled switching system. Because in the absence of mechanical wear, brushless motor in addition to improving the life, but also reduces the noise. Due to the cancellation of the traditional brush, so the brushless system is shorter and lighter. In addition, the brushless motor has better electromagnetic compatibility; it allows the vehicle to avoid interference with the operation of digital systems.
  Brushless motor can be well applied to the cooling fan assembly. They can improve the efficiency of ten percent and about 400 grams lighter than conventional motor. When the vehicle is running at full capacity, Approximately 3 grams of carbon dioxide emissions can be reduced per kilometer. It is worth mentioning that, ac Brushless motor is better than DC brushless motor in improving vehicle dioxide emissions.
