With the government to stimulate domestic policy effect of the gradual emergence of the international economic situation and the improvement of the linear motor industry sales rebounded significantly, supply and demand improved, the industry profitability steadily improved. Linear motor is facing huge market investment opportunities, and now more and more enterprises aware of the advantages of linear motor, making the linear motor has been widely used. This paper mainly introduces the application of linear motor in power tool.
　　In the past in the wood processing industry, the use of rotating motor driven band saw a total speed of 25-50m / s (90-18km / h) high speed range, the need for larger power motor. When using a rotating motor. The diameter of the drag wheel on the representative saw is 1.8-3 m, and when the drag wheel size becomes large, the time for acceleration and deceleration is also increased. Colleagues, band saw itself has become larger, to the trailer handling has brought difficulties.
　　In order to overcome the shortcomings of rotating motor drive band saws, people use linear motor drive band saw program. This band saw is a double-sided linear motor secondary conductor as a saw blade.
　　The secondary guide bar is the material of the saw blade that uses a non-magnetic, high-strength and high-elastic beryllium bronze. Because it needs to work at high speed, so the excitation frequency is 60Hz or more. This band saw is not only simple to change the direction, but also for high-speed reverse braking with high response performance.
　　The diameter of the tug with a linear motor band saw is 62mm, which is reduced to 1 / 3-1 / 4 of the conventional band saw tug, so that the band saw can be miniaturized. It is said that this band saw for the maximum diameter of 50cm of wood processing, three-phase AC can guarantee more than 40m / s speed.
　　Linear motors are now widely used in many industries, including: laser cutting equipment industry, semiconductor manufacturing equipment industry, flat panel display industry, printing equipment industry, medical equipment industry, precision testing equipment industry, electronic components surface mount equipment industry, PCB testing Equipment industry, logistics equipment industry and other different areas.
