Linear motors are a type of motor, also known as linear motors or DC motors. It differs from conventional motors in that its rotor moves along a straight track rather than rotating. Linear motors are widely used because of their high power density, high speed and accuracy. The world's first linear motor was developed in the early 1960s. Since then, its application fields have been expanding, especially in the field of simulation motion and precision machining equipment.

The working principle of linear motor is to drive linear motion through electromagnetic field. In a linear motor, there are two main parts - one is the stator part and the other is the rotor part. Unlike conventional motors, both the stator and rotor are linear and move on the same axis. The stator receives an electric current and generates a magnetic field through which the rotor is forced to move. Accurate control and regulation of the current causes the rotor to move forward or backward in a linear trajectory.

Linear motors have many advantages. It can achieve high-precision motion in large machines, which is often not possible with traditional motors. Its mechanical components are lightweight and simple in structure, and have faster response times. In addition, because there are no rotating parts, the noise is low at high speed, which is ideal for satellites and other space applications.

Linear motors are widely used, for example, in the field of industrial automation, they are used for conveying and loading materials, assembly lines, precision machining and so on. In addition, it is also widely used in the field of linear propulsion systems and precision medical equipment.

In short, the linear motor is a type of mechatronics motor, because of its high-precision control, high power density, high speed and fast response time and other characteristics of attention. In the future, it is expected to continue to be widely used in mechanical engineering, satellite space, meteorological equipment and other fields.
