The general motor is constructed on the middle shaft with a "rotor" that can be rotated, surrounded by a "stator", and a magnetic field can be generated after the coil is energized. The so-called "linear motor" is to cut the motor along the axis direction and expand it. The return of the motor is converted into a linear motion, so it is called a linear motor. The motor moving with a track must not only bear the load, but also bear the quality of the track, but there is no need for a cable management system. The advantages of linear motors are: simple structure, fast response speed, high sensitivity, good portability, good sealing, no fear of pollution, strong adaptability, stable and reliable work, and long life.
As we mentioned above, "long life" is one of the advantages of linear motor, but there are many other factors affecting the life of linear motor, this paper together with Mao linear motor for you to introduce some factors affecting linear motor life.
The moving quality ratio determines the load capacity of the linear motor. Small moving quality represents higher additional load capacity. In addition, high moving quality will produce considerable vibrations to your machine during high acceleration and deceleration, and may lead to unpredictable resonance. Therefore, A good linear motor has to make its moving quality smaller and better.
In some applications, the dual axis simultaneous high acceleration and deceleration movement is a basic requirement. Most of the motion modules only overlap one axis directly on another axis, which will lead to a very large difference in the bandwidth of the two axes. For example, When the X axis is stacked on the Y axis, the X axis motor only needs to load its own moving quality, and the Y axis load still needs to bear the quality of the entire X axis platform in addition to its own moving quality. This configuration is called &;; Quot; Duplicate XY platform & amp; Quot; And ... In order to make the bandwidth of the two axes similar, the moving quality of the two axes can be isolated using the solution mechanism. In this way, the motors of each shaft only need to bear their own moving quality and share slides. This configuration is called &;; Quot; Solution XY platform & amp; Quot; And ... It is very important to determine the rated output of the linear motor. In most cases, the linear motor can not move all the time. It may stop for a period of time waiting for motion like image correction or other axis. We know that the size of the linear motor is related to his rated output and has nothing to do with the effective large output, so we have to be very careful about deciding either the distance or the motion file, otherwise your linear motor will be too large and take up space. Or too small and cause the motor to overheat.
Mobile cable is an important factor in the life of a linear motor platform. A good linear motor platform has to make its mobile cable less and better. If the journey is not long, use &; Quot; Magnetar style & amp; Quot; Configuration & coordination Quot; Fixed optical ruler reader & amp; Quot; The removal of mobile cables is very important for high-frequency high-acceleration and deceleration applications.
The linear motor has compact structure, low power loss, high fast moving speed, high acceleration and high speed. By directly driving the load, the linear motor can achieve high-precision position location control from high speed to low speed. We believe that as long as the linear motor is used correctly, the advantages of long life of the linear motor will be more prominent.
