▋ Market Analysis of DC Brushless Electric Tools
Overview of the Electric Tool Market：
In recent years, the electric tool industry has shown a rapid development trend. For many years, China's electric tools have mainly been exported, accounting for 85% to 90% of the total production, and the domestic market sales account for 10% to 15% of the share. Despite the large export of domestic electric tools, the market share of domestic electric tools still exceeds 90% in the domestic market. In the foreign power tool market, China's manufacturing proportion continues to expand, accounting for 90% of global production, making China a major exporter of power tool products and a global power tool production base. The industry has enormous development potential. Professional electric tools for industries with high technological content and strict performance requirements in China still have a large latent market in European and American countries. At present, in industrial countries in economically developed regions, such as Germany, Britain, the Netherlands, France and other countries in Europe, the United States, Canada in North America, Japan in Asia and other countries, the use of electric tools in home homework is very common, accounting for about 50% to 70% of the total output. China's electric tool products have occupied a large share of the domestic electric tool market in the above countries and regions. Based on the sales revenue of the electric tool market in the past five years, it is predicted that the sales revenue of China's electric tool industry will reach approximately 128.3 billion yuan by 2018, indicating a significant potential for market demand growth.
Electric tools are divided into three main types：
1．Hand-Held Motor-Operated Electric Tools
2．Mobile electric tools
3．Garden electric tools
According to the power supply method, it can be divided into two types:
1．High voltage AC power tools based on AC power supply
2．Low voltage DC electric tools powered by batteries (battery voltage not exceeding 75V)
▋ Development direction of electric tools
Development direction of electric tools：
As the technology of power lithium batteries becomes more mature and costs continue to decrease, rechargeable handheld electric tools using lithium-ion batteries are gradually replacing traditional AC electric tools. The main advantages of handheld rechargeable electric tools are:
- Convenient to move, it can work normally in places without mains power and during power outages.
- The handheld rechargeable electric tool adopts a brushless motor, free of carbon brush maintenance, and does not generate dust. It can be used in a dust-free room.
- Handheld electric tools use brushless motors for higher efficiency, energy conservation, and emission reduction.
- Brushless motor is used for hand-held electric tools to reduce the running noise and Noise pollution.
- Equivalent power handheld electric tools have higher power density, smaller size, and are easy to carry.
- Handheld electric tools have a higher starting torque.
Brushless electric tools mainly consist of the following parts:
▋ Selection and cooperation of power devices for drive boards
Selection of Drive Board Power Devices：
The majority of handheld brushless electric tools are powered by 18V lithium batteries. For 18V drive boards, the main power is around 300W, corresponding to our MOS part number: NCE40H20 (40V 200A 3.3mR) NCE40H20A (40V 200A 2.0mR) NCE40H12K (40V 120A 4.0mR)
Competitor's part number: HY4004 (40V 208A 2.5mR) HY4504 (40V 250A 2.3mR) 11V driver board, corresponding MOS part number: 30H10A 3080K, etc.
