As one of the common application tools in household and industrial fields, power tools can be found everywhere, such as electric drills, electric saws, electric grinding tools, electric planers, etc., and their application range is very wide, including mechanical industry, construction and decoration, landscaping, wood industry processing, financial processing, etc. It is undeniable that power tools play an indispensable role in social and economic development. As the largest developing country in China, power tools are therefore classified into the category of advanced equipment manufacturing.
Among them, lithium batteries have attracted more and more attention due to their high energy density, high recycle times, light weight, and green environmental protection. Therefore, they have been widely used in portable handheld devices such as mobile phones, laptops, and power tools. Lithium battery protection solutions have also become an exploration direction for power tool companies. Benefiting from breakthroughs in lithium battery technology, power tools are gradually switching to clean energy. The battery capacity and safety of power tools are expected to be greatly improved, while battery costs continue to decrease.
The brushless motor with non-inductive control is very important for the starting, commutation and braking of the motor and realizing the operation of the motor. When it is applied to power tools, the control of brushless motors is different depending on the characteristics of the tool. As the penetration rate in the home increases, power tools need to serve a variety of purposes. At the same time, breakthroughs in electronic control technology have brought intelligent tools into the home, and the industry has huge development potential.
