The working principle of the linear motor coil is based on the principle of electromagnetic induction. When current is passed through the coil, a magnetic field is generated around the coil. According to the ampere's principle, the current in the conductor will produce force under the action of the magnetic field, which is the working basis of the linear motor coil.
In a linear motor coil, there are usually two main elements, the coil and the magnet. The magnet may be a permanent magnet or an electromagnet that generates a magnetic field by an electric current. When energized, the magnetic field generated in the coil interacts with the magnet. According to the principle of Lorentz force, the coil will be subjected to a force in one direction. Depending on the direction and magnitude of the current, the coil can achieve linear motion in both forward and reverse directions.
Linear motor coils are widely used in industrial automation, robotics and other fields. It has the advantages of simple structure, high precision and fast response speed, and is suitable for occasions requiring precise control.
In summary, the linear motor coil achieves linear motion through the interaction between the magnetic field generated in the coil by the current and the magnet. Its working principle is simple and intuitive, widely used, and is an important part of modern engineering technology.
