Linear motor market advantage highlights
Since its inception, Jacques has been committed to innovation and research and development of new technologies and solutions, including more than 15 patent licenses and 6 patents pending approval for semiconductors, solar, flat panel displays, hard drives, LEDs, printed circuits. Professional support is provided in a wide range of industries including board, printing, optics and biomedicine. Yakebeth's agents in China mainly include Shenzhen Taidao Precision Electromechanical Co., Ltd. and Shenzhen Meilake Technology Co., Ltd., etc., mainly acting as Yakebeisi linear motor, voice coil motor, torque motor, ball screw platform, and more. Axle platform, voice coil motor platform and precision system solutions.
As a company with a high market share in linear motors, Jacques is committed to the development and manufacture of linear motors. The linear motor can be regarded as a principle in which the conventional servo motor is cut in the radial direction and the circumference of the motor is developed into a straight line. When the coil (mover) is energized, a magnetic field is generated in the air gap between the stators, and the magnetic field is cut by the magnetic field and the permanent magnet of the stator to generate a driving force, thereby achieving linear motion. It is divided into two types: ironless linear motor (U type motor) and iron core linear motor (flat motor). The ironless linear motor has only the coil and no magnet, and there is no suction between the moving stator. Without the cogging effect, it is easy to achieve smoother motion and achieve higher precision. However, the iron core linear motor mover has only a magnet inside the coil, and there is a strong suction between the moving stator, which can generate a large thrust.
Relatively speaking, linear motors have many unique advantages, such as very high speed, very low speed, high acceleration, high precision and so on. Moreover, the completion of linear motion requires only a motor without the need for gears, couplings or pulleys, which is important for many applications.
Linear motors are mainly used in three aspects: first, they are applied to automatic control systems, and there are many such applications; secondly, they are used as long-term continuous running motor; third, applications require large linear motion in short time and short distance. In the device.
The high-speed maglev train is the most typical example of the practical application of linear motors. The United States, Britain, Japan, France, Germany, Canada and other countries are developing linear suspension trains; in April 1990, in the Wanshi Building, Toshima, Tokyo, Japan, linear motors The driver was first applied to the elevator. This linear motor-driven elevator has a load capacity of 600kg, a speed of 105m/min and a lifting height of 22.9m.
In addition, when the rotation exceeds a certain limit, the motor using the rolling bearing will cause sintering and damage. A linear suspension motor (electromagnetic bearing) has been developed abroad, which uses suspension technology to suspend the motor's mover in the air, eliminating the The mechanical contact and frictional resistance between the mover and the stator can reach a speed of 25,000-100000r/min or more, which is widely used in high-speed motors and high-speed spindle components.
