As the new technology and way of life changing, step by step into the era of brushless electric tools. Especially lifestyle changes and the improvement of quality requirements, the Chinese family, the number of electric tools type, technology, etc are growing rapidly. The brushless electric construction have what advantage? Specific introduction: (below small make up for you)Province electric brushless motor without carbon brush rotor complete rotate freely without any frictional resistance along with the computer precision control the rotation of the rotor Angle will not waste any energy so very save electricity many tools official labeling power brushless three hundreds of more than six hundred watts looks very inefficient but you will find that the battery is carried in practical use. ()Torque brushless torque tools is very big, many times more than a brush tool is one of the most obvious place is the output of the low speed torque such as electric drill, have almost no torsion brush drill below thirty percent speed, between thirty percent and fifty percent, and torsion is less than a third of the maximum torque, only high speed, torque will resume normal work, this brushless electric drill crushed brush drill. Under any speed brushless electric drill output torque is almost the same low speed also has large output torque even five percent speed torque has more than seventy percent say again, maximum torque: you know the size of the output shaft torque not only depends on the motor and see how many level reduction gear brushless motor because it has no abrasion resistance and high wear life speed can be done without reducing the output shaft speed, can add level or two-stage reduction gear will greatly improve the output torque can beat any brush motor. ()Brushless speed can be precisely controlled speed. Brushless motor rotor on the installation Angle sensor magnets, the rotor behind three hall sensors microcontroller can every moment of the monitoring of rotor Angle and rotational speed. The detection is very accurate, he decided the electric timing of stator coil and electric current if tools for heavy work, the rotor speed to reduce the Angle is not correct, the computer can give a stator coil higher voltage and larger current in order to keep the rotor speed will not reduce, this is why when low speed torque brushless motor stator coil when low speed will have huge high voltage and large current generate strong magnetic field twist rotor. Brushless tool rotation speed can be accurately adjusted.
