The present invention relates to a magnetic levitation conveying system, and more particularly, to an improved seed flux type magnetic levitation conveying by increasing the guiding force by employing a plurality of teeth and slots in an existing seed flux levitation conveying system. It's about the system.

The magnetic levitation conveying system transfers objects without mechanical contact or friction to realize a noiseless, ultra-clean conveying system. In general, the magnetic levitation transfer system requires floating force, guiding force, and driving force, which is provided with floating force and guiding force from the floating electromagnet, and propulsion force from the linear motor. That is, by controlling the current flowing through the winding of the electromagnet to obtain a floating force to maintain a constant gap between the electromagnet and the rail, and to generate a guide force in the horizontal direction between the electromagnet and the rail so that the moving body does not leave the track.

An electromagnet 100 consisting of a pair of annular windings 104 having an iron core 102 having a shape and a hollow portion into which both magnetic pole portions 103 of the iron core 102 are inserted, and the electromagnet 100 It consists of a rail 106 formed along the direction of movement while maintaining the end portion of the pole portion 103 and a predetermined gap (g). In addition, each end portion of the electromagnet core 102 in which both magnetic pole portions 103 and the rail 106 face each other is formed in a substantially rectangular plane.

2 is a cross-sectional view showing the lifting force and the guide force in the conventional seed flux magnetic levitation transfer system. As shown in FIG. 2, the width a of the cross section of the magnetic pole part 103 of the electromagnet core 102 of the conventional seed flux magnetic levitation conveying system is equal to the width of the rail 106. The force F ₁ is formed between the electromagnet 100 and the rail 106 when the magnetic pole portion of the electromagnet iron core 102 moves dx in the width direction from the center axis of the rail in a state where current flows through the electromagnet winding 104. The force F ₁ may be divided into a horizontal force Fx ₁ and a vertical force Fy ₁ . The horizontal force Fx ₁ acts as a restoring force, ie, a guide force, in which the central axis of each of the electromagnets and the rails tries to coincide to minimize the magnetoresistance between the electromagnet core 102 and the rail 106, and the vertical force Fy ₁ acts as a flotation force. However, the magnetic levitation transfer system as described above has a problem in that it cannot be used in a system requiring a large guiding force because there is a limit in the amount of guiding force in the horizontal direction.

Therefore, when a large guide force in the horizontal direction is required to solve the above problems, the conventional magnetic levitation transfer system was installed separately an electromagnet for obtaining the guide force in the horizontal direction. However, the method of separately installing the guide electromagnet has many problems such as complicated structure of the entire system, increased space required, delayed installation period, and the like.

In addition, the existing magnetic levitation system is a transverse magnetic flux method is mostly installed in the transverse direction of the electromagnetic winding on the rail, this method has a problem that the space occupied by the winding and the rail becomes large.

The present invention is to solve the problems of the conventional seed flux magnetic levitation transfer system, by implementing a seed flux type magnetic levitation transfer system employing a plurality (two or more) of teeth and slots It is intended to be applied to a magnetic levitation conveying system which requires a large horizontal guiding force.

In addition, the seed flux type magnetic levitation transfer system according to the present invention does not require a separate guide electromagnet because the guiding force in the horizontal direction is increased, and the winding and the rail occupy by using the seed flux type electromagnet in which the electromagnet winding and the rail are installed in the longitudinal direction. The aim is to obtain a magnetic levitation transfer system with an improved structure that can be applied to a relatively narrow area by greatly reducing its area.
