Increasingly perfect as the technique of linear motor, linear motor is also down gradually, the application of linear motor has become increasingly widespread, but this information is rarely on the market, so there are a lot of people don't understand linear motor. Linear motor can be thought of as a rotary motor in a kind of structure deformation, it can be seen as a rotary motor along its radial cut open, and then close the evolution and into. Compared with linear motor and rotary motor, mainly has the following features: one is simple in structure, due to the linear motor don't need a rotation movement into linear motion of the additional device, thus making the structure of the system itself greatly simplified, weight and volume is greatly decreased; Second, high positioning accuracy, where the need to linear motion, linear motor can realize direct drive, it can eliminate the intermediate links of various positioning error, so the high positioning accuracy, such as using microcomputer control, can greatly increase the positioning accuracy of the whole system is also; Third, fast response, high sensitivity, good follow-up. Linear motor easy to do it by using magnetic levitation support, making the child and always maintain a certain air gap between the stator and do not contact, this eliminates the constant, dynamic contact between the friction resistance, thus greatly improves the system's sensitivity, rapidity and follow-up; Four is safe and reliable work, long service life. Linear motor can realize non-contact and heritability of mechanical friction loss is almost zero, so less faults, maintenance free, thus work safe and reliable, long life. Linear motor is mainly used in three aspects: one is applied to automatic control system, such as more applications; The second is the drive motor as long-term continuous operation; 3 it is used in need a short time, can provide huge linear motion device over short distances. ——High-speed maglev train the maglev linear motor is the most typical example of practical application, at present, the United States, Britain, Japan, France, Germany, Canada and other countries in developing linear suspension train, the fastest progress in Japan. ——Elevator driven by linear motor of the world's first use of the elevator driven by linear motor is installed in April 1990 in Japan Tokyo Guam area ambient building, the elevator load of 600 kg, the rate of 105 m/min, hoisting height is 22. 9m。 Because the elevator without traction unit driven by linear motor, thus computer room on the top of the building can be omitted. If the height of the building to 1000 meters, no elevator wire rope must be used, the elevator using high temperature superconducting technology, driven by linear motor coil is installed in the shaft, outside capsules containing high performance permanent magnetic materials, such as maglev train, the use of radio waves or optical technology control. ——Ultra high speed motor in rotating exceeds a certain limit, using rolling bearing motor can produce sintering, damage phenomenon. Therefore, in recent years, a linear suspension motor is developed abroad (The electromagnetic bearing), the use of suspension technology makes the motor still suspended in the air, eliminates the active cell and mechanical contact and friction between the stator resistance, its speed can reach more than 25000 ~ 100000 r/min, resulting in high speed motor and has been widely used in high speed spindle components. Such as Japan yaskawa company newly developed more process with 5 axis nc lathe automatically controlled electromagnetic high-speed spindle is made of two after the electromagnetic bearings and one axial thrust magnetic bearing, can inherit the load of machine tool in any direction. In the middle of the shaft, except for to have high-speed motor, also equipped with a compatible with multistep automatic CNC lathe tool automatic switching mechanism. We have reason to believe that, linear motor will infuse new power for the development of industry in China. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
