Background
A linear motor is an electric drive device that converts electrical energy directly into linear motion mechanical energy. It can save a lot of intermediate transmission mechanisms, accelerate the system reflection speed and improve the system degree, so it is widely used. The side of the linear motor from which the stator evolves is called the primary and the side from which the rotor evolves is called the secondary. In practice, the primary and secondary are manufactured in different lengths to ensure that the coupling between the primary and secondary remains constant over the required range of travel. The linear motor can be a short primary long secondary and can also be a long primary short secondary. In consideration of manufacturing cost and operating cost, short primary and long secondary are generally adopted at present. Linear motors operate on a similar principle to rotary motors. Taking a linear induction motor as an example: when the primary winding is connected with an AC power supply, a travelling wave magnetic field is generated in the air gap, and the secondary winding is cut by the travelling wave magnetic field to induce electromotive force and generate current, and the current and the magnetic field in the air gap interact to generate electromagnetic thrust. If the primary is fixed, the secondary moves linearly under the action of thrust; otherwise, the primary stage moves linearly. Linear motor drive control technology a linear motor application system not only needs to have a linear motor with good performance, but also needs to have a control system capable of realizing technical and economic requirements under safe and reliable conditions. With the development of automatic control technology and microcomputer technology, linear motors are increasingly controlled.
