The advantages of brushless electric wrenches versus brushes

The advantages of brushless electric wrenches versus brushes

Answer:

Theoretically, the life of a brushless electric wrench can be up to 20 years. Brushless electric wrenches no longer use gear reducers, thus avoiding the loss of efficiency in gear transmission, making the efficiency up to 80-85%, and greatly reducing noise.
However, because of the brushless electric wrench for low cost, small volume, light weight, the use of electric bicycle, so that there are two major technical problems, a small torque, there will be two low speed vibration, some electric bicycle manufacturers to the actual use of brushless electric wrench. With the development of modern science and technology at present. It is reported that, the technology leader in the electric bicycle industry in the electric wrench factory has successfully solved these two problems, so that the torque brushless motor with a brush pressing type motor, low vibration has been controlled in the range of the general feel. The motor will naturally become the ideal and high efficiency high torque, low noise, long continuous force to the target, the brushless electric wrench will become the main electric wrench for electric bikes in the next few years.
The difference between brushless electric wrench and brush electric wrench is a brushless electric wrench with digital control circuit commutation and speed reducer, electric wrench. Brushless electric wrench is no longer the use of mechanical brush commutation device solves the problem of life brush electric wrench insurmountable.
