It is well known that linear motors are widely used in various industrial fields, including flat panel displays (FPD), semiconductors, automation, medical diagnostics, 3D printing and machine tools. Constant speed control is essential for these advanced industrial processes. Seidal is a leading supplier of high precision linear motor systems. Its series of advanced linear motor systems use its own patented technology to meet the needs of advanced industries.  The MTF Linear Motors do not use magnets on the stator, but the powder magnetic conductive materials developed in recent years. The material has the characteristics of high permeability, high saturation flux and easy metallurgical die casting. Magnetic-track-free linear motor is also a permanent magnet synchronous motor, its external characteristics and rotating permanent magnet synchronous motor and linear motor is no different.Magnetic-track-free linear motor puts the magnet inside the actuator, and when the actuator moves, the corresponding magnet moves. In other words, the motor will have the excitation of the magnet with movement, the magnet movement to which part, which part of the electromagnetic force. Thus, as the rotary permanent magnet synchronous motor, the magnet utilization rate reaches 100%, no additional magnet is exposed. It can effectively overcome the disadvantages of large magnet consumption and low utilization rate of the conventional linear motor. Thus, the cost of linear motors is greatly reduced and safety is improved. Compared with high-cost magnetic rail linear motors on the market, our linear motors can save a large amount of rare earth materials and save at least 70% of the cost, especially for long-track linear motors.  Our Linear Motor Module is worth having.  In the future, our Linear Motor Application will become more and more widespread.

How nonmagnetic track Linear Motor Module works?

About SEIDAL MTF linear motor working principle, the most basic electromagnetic theory is still unchanged, but it adopts the latest magnetic field modulation theory, self-modulated ferroalloy stator. We transfer the magnet supposed to be laid on the stator to the mover, so that the coil and magnet are integrated on the mover.The synonym-shaped design on the stator provides a magnetic circuit that essentially interacts with two magnetic fields to generate thrust.

When the mover moves, the corresponding magnet also moves with it. That is, the activist will have an excitation magnet with a movement, magnet movement to which part, which part produces electromagnetic force. Thus, like the rotating permanent magnet synchronous motor, the magnet utilization rate reaches 100%, and no extra magnets are exposed. The design of this structure overcomes two shortcomings of conventional linear motors.Namely, the large amount of magnets and the low utilization rate. This greatly reduces the cost of linear motors and improves safety.
