In power tool design and consumer choose and buy, often speak of brushless and brush, they mainly refers to the brushless motor and a brush. Many enterprises at home and abroad of the high-end product is the brushless motor combination, because its have long service life, save electricity, small size, high performance, strong JingMiXing advantage. The current development speed - at homeYears there will be a large number of brushless motor output, then there will be a large number of domestic brand brushless tools on the market. Brushless foreign brands of products, short-term price adjustment is unlikely, larger domestic brushless too little, after all. In a global perspectiveYears (Domestic manufacturers impact and other factors)Inside the line into the appropriate price adjustment, also in the update product line. But in brushless from the use of performance, manufacturing perspective there is still a certain gap, brushless motor development is still in a low speed, most vendors don't have the ability to mainstream manufacturers use brushless, medium and small electric tools on the market, such as Angle grinder, small toothless saw, grinder and so on are still predominantly a brushless ac motor. Consumer end user and whole machine factory have reaction, brushless motor electric tools is a brush more than double the price, its controller is complex, the late failure is difficult to rule out, and in the manufacture and maintenance cost high, brushless electric tools is higher than a brush electric tools, mainly from the homework about the noise rang in grinding, sawing, itself is not a lot to do with motor. Brushless electric tools will no doubt go, but there are still more distant distance brushless era. But in brushless from the use of performance, manufacturing perspective there is still a certain gap, most vendors don't have the ability to mainstream manufacturers use brushless. Now, our country electric tools production accounted for % of the world, including cordless rechargeable tools accounted for % of the total, lithium battery accounted for %, mainstream brand overtones (Fein）, festo (Festool), Bosch (Bosch), black &decker (黑色的Decker), wei (德瓦尔特), m a swatch, wheat Pacific, gains hiliti and grazing fields (xi,Makita)Companies such as high-end products are mostly adopted the lithium battery and the combination of the brushless motor. Domestic brands are accelerate, such as go and wake and comprehensive to lithium electricity, quickly eliminate nickel cadmium, other manufacturers are using lithium electricity. Combined with the real estate market rebounded sharply and infrastructure in the developing world rapidly large-scale expansion of market demand, improve the professional customers cordless power tools market is growing continuously. But cordless power tools need to be recharged after use, the energy from the battery to get as much, and then use energy as efficiently as possible, the two key challenges facing become a tool for designers. According to the analysis of electric tools in the domestic market concentration in gradually improve,Out more), but the quality of foreign investment is very strong, especially in the technology, brand, management, sales channels leading is bigger. Due to the recent continuous attention to the industry product development power tools, can think so, now electric tools development speed in the trough, the overall smooth, leading electrical tools manufacturer's flagship product in the comprehensive upgrading of lithium electricity after the slow progress in several years. The brushless motor in the iteration, generation after we could hardly see any breakthrough, temporarily brushless also is at the early stage of popularization. At the same time aware of lithium battery and brushless motor is the mainstream of present and future power tools technology development. As the new technology and way of life changing, gradually into the brushless electric tools, cordless era.
