The theory of field modulation states that the magnet and coil need not be in relative motion in order to obtain a sinusoidal flux in the coil, which is a necessary condition for a permanent magnet synchronous motor. The same effect can be achieved by using a modulator outside the magnet and coil. Therefore, the magnetic-track-free linear motor does 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, its back potential waveform is symmetric three-phase sine, drive mode is frequency conversion vector control.  The 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 Non Magnetic Track linear motor works?

About our MTF Linear Motors 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.
