The role of linear motor module in laser cutting machine

A laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing it to reach its melting or boiling point, while the high-pressure gas coaxial with the beam blows away the melted or vaporized metal. Laser cutting processing replaces traditional mechanical knives with invisible beams of light. It has the characteristics of high precision, fast cutting, not limited to cutting pattern limitations, automatic layout saving materials, smooth cutting, and low processing costs. It will gradually improve or replace traditional metal cutting equipment.

Metal laser cutting machines are widely used in many industries and are one of the essential equipment for many enterprises. They are widely used in sheet metal processing, advertising label production, high and low voltage electrical cabinet production, mechanical parts, kitchenware, automobiles, machinery, metal handicrafts, saw blades, electrical parts, glasses industry, spring blades, circuit boards, electric kettles, medical microelectronics, hardware, cutting tools and other industries.

The linear module plays an important role in laser cutting equipment, in addition to the laser, cutting head, and machine tool, as well as the linear motor. As an important driving device, linear motors are different from traditional rotation methods. The linear motor module driving method has high dynamic characteristics, high control accuracy, and long service life.

A linear motor module is a transmission device that directly converts electrical energy into mechanical energy for linear motion, without the need for an intermediate conversion structure. When the winding is connected to an AC power source, a traveling wave magnetic field is generated in the air gap. Under the cutting of the secondary traveling wave magnetic field, an electromotive force is induced to generate current. When the current interacts with the magnetic field in the air gap, electromagnetic thrust is generated. If the main rod is fixed, the auxiliary rod moves in a straight line under the action of thrust. On the contrary, the actions of beginners are linear.

Linear motor modules have been used in many fields in the market, but laser cutting, as a force free machining method, has great advantages in using linear motor feed drive.
