In the history of linear motor development, linear motors can convert electrical energy into linear motion without any intermediate conversion structure. Compared with traditional methods, linear motors have the advantages of low noise, no wear, no contact, simple structure, high speed, and high precision.
Traditional elevator traction system and door machine use AC rotating electrical machine to work, in order to achieve the opening and closing of the elevator door, the need to use some of the more complex rotating mechanism to the rotary motion of the motor into a linear motion. For elevator traction drive system, whether AC motor worm drive system or AC speed control system, or permanent magnet motor speed control system, because the AC motor slow response, control more complex, can not meet the future Elevator performance requirements. The linear motor because of its particularity of the structure, not easily affected by the environment, has been widespread concern in the industry, is gradually becoming all walks of life.
The concept of linear motors was proposed in 1840 and has a history of more than 100 years. The history of its development can be roughly divided into three stages, namely: exploring the experimental stage, development and application stage and practical commercialization stage.
The first phase refers to the exploration and experiment phase of linear motors. At this stage, there are still some problems in the design of linear motors, and there is no suitable application field for linear motors. Therefore, linear motors have not been widely used.
In the development phase, scientists have made great research results on the basis of linear motor research, and published a number of relatively systematic motor works and articles, which have greatly promoted the development of linear motors, and have also led to a large number of researchers. The importance of linear motors.
Since 1971, linear motors have been used independently. At this stage, researchers have chosen ways to use linear motors. Various types of linear motors have been widely promoted and many useful values have been studied. Of products, such as punching machine, air compressor, coal machine and so on.
In recent years, linear motors have been rapidly developed and many people have begun to study linear motors. A variety of good quality linear motor products also appeared in people's vision. Such as Kunshan Tongmao independently developed a very complete series of linear motors, which includes a core of linear motors and coreless linear motors. A very standard interface is set in the control system of the linear motor, which can better guarantee the compatibility of various landscape-modified program controllers and digital converters.
The research and development of linear motor in our country is relatively late, probably developed from the 1970s. However, under the influence of the trend of the use of linear motors in foreign countries, many units of linear motor development have also emerged in China. For example, Kunshan Tongmao Electronics Co., Ltd. is a linear motor technology research and development, linear motor, voice coil motor, precision Linear platform manufacturing and sales as one of the manufacturers. Produced by the company's high-quality, high-performance linear motor, voice coil motor and precision linear platform using advanced technology standards in Europe and America, technology and testing methods, its quality and power performance reached the international advanced level, can completely replace similar foreign products.
