detailed description

Example 1:

Referring to FIG. 1, between the two annular yokes of the inner ring and the outer ring, a first electromagnetic coil A and a first permanent magnet C, a second electromagnetic coil A1 and a second permanent magnet are sequentially disposed at intervals. C1 (the first electromagnetic coil A and the second electromagnetic coil A1 are respectively disposed on two soft magnetic cores or yokes respectively connected to the two annular yokes at both ends, and the first electromagnetic coil A and the second electromagnetic coil A1 has the opposite direction of the magnetic field. When the electromagnetic coils A and A1 are connected to the AC power source, the electromagnetic coils A and A1 generate an alternating magnetic field; since the circuits between the electromagnetic coils A and A1 are connected in series, that is, the head end of the electromagnetic coil A1 and The ends of the electromagnetic coil A are connected, so that the magnetic field generated between the two is opposite in direction, that is, when the first electromagnetic coil A is located at one end of the outer ring yoke, the magnetic pole is N pole, and the second electromagnetic coil A1 is located at one end of the outer ring yoke. For the S pole.

As shown in the figure, when the first electromagnetic coil A is located at one end of the outer ring and is N pole, and the end of the inner ring is S pole, the magnetic field direction of the electromagnetic coil A and the S pole are on the outer ring and the N pole is located on the inner ring. The magnetic field of the second permanent magnet C1 is opposite in direction, and the closed magnetic circuit is formed by the outer ring yoke and the inner ring yoke. The magnetic field strength in the closed magnetic circuit is the sum of the magnetic field strength of the electromagnetic coil A and the magnetic field strength of the permanent magnet C1, and the second induction coil B1 located in the closed magnetic circuit is induced by the magnetic field to generate an induced current, the induced current The magnitude is equal to the sum of the induced currents generated by both the electromagnetic field of the electromagnetic coil A and the magnetic field of the second permanent magnet C1.

Since the (power source) of the first electromagnetic coil A and the second electromagnetic coil A1 are connected in series (the coil A tail power supply line and the head end of the coil A1 are connected), when the first electromagnetic coil A is located at one end of the outer ring, the magnetic pole is extremely N pole. The magnetic pole of one end of the electromagnetic coil A1 located on the outer ring yoke is S pole at the same time, and the second electromagnetic coil located on the inner ring yoke when one end of the first electromagnetic coil A on the inner ring yoke is magnetically S pole The magnetic pole of one end of A1 is N pole at the same time. Due to the principle of isotropic reciprocal attraction, the magnetic field generated by the second electromagnetic coil A1 can only form a magnetic field loop through the first permanent magnet C through the outer ring yoke and the inner ring yoke. The magnetic field strength is equal to the sum of the magnetic field strengths generated by both the second electromagnetic coil A1 and the first permanent magnet C. The fourth induction coil B3 is located on the formed magnetic field loop between the second electromagnetic coil A1 and the first permanent magnet C, and the fourth induction coil B3 generates an induced current due to the magnetic field induction. The magnitude of the induced current is equal to the sum of the induced current generated between the magnetic field generated by the second electromagnetic coil A1 and the magnetic field generated by the first permanent magnet C.

Also, due to the principle of homosexual reciprocal attraction, the first permanent magnet C has the same magnetic field direction and the direction of the magnetic field between the first electromagnetic coil A, and the N poles of both are oriented toward the outer ring yoke, and the S poles are all oriented inward. The ring yokes are mutually repelled in the magnetic circuit, and the magnetic loops cannot be formed by the outer ring yoke and the inner ring yoke, so that they are located on the yoke between the first electromagnetic coil A and the first permanent magnet C. The intensity of the magnetic field induced by the first induction coil B is zero, and there is no magnetic field induction and induced current generation in the induction coil B. Meanwhile, the third induction coil B2 located on the yoke between the second permanent magnet C1 and the second electromagnetic coil A1 is also the same as the magnetic field between the second permanent magnet C1 and the second electromagnetic coil A1, the magnetic field and the magnetic field Repelling each other, the magnetic loop can not be formed by the outer ring yoke and the inner ring yoke, so the third induction coil B2 located on the magnetic path between the second permanent magnet C1 and the second electromagnetic coil A1 is induced. The magnetic field strength is also zero, and the induced current cannot be generated on the third induction coil B2.

Referring to FIG. 1-1, since the first electromagnetic coil A and the second electromagnetic coil A1 are connected to an alternating current whose current direction is constantly changing, when the current direction changes, the first between the inner ring and the outer ring The magnetic field directions of one electromagnetic coil A and the second electromagnetic coil A1 change simultaneously, the original N pole becomes the S pole, and the original S pole becomes the N pole. According to the principle of homosexual repelling opposite sex, when the first electromagnetic coil A One end on the outer ring is an S pole, and when one end of the inner ring is an N pole, the first electromagnetic coil A and the first permanent magnet C opposite to the magnetic field direction are formed by an outer ring yoke and an inner ring yoke. The magnetic field loop, the first induction coil B located on the magnetic circuit between the two generates an induced current through the magnetic field. At the same time, the second electromagnetic coil A1 and the second permanent magnet C1 having the opposite magnetic field direction form a magnetic field loop through the outer ring yoke and the inner ring yoke, and the third induction coil B2 located on the magnetic path between the two generates the induction through the magnetic field. Current. Since the magnetic field direction between the first electromagnetic coil A and the second permanent magnet C1 is the same, the two magnetic fields repel each other, and the magnetic loop can not be formed by the outer ring yoke and the inner ring yoke, so the two are located The second induction coil B1 on the yoke cannot generate an induced current; and the fourth induction coil B3 located between the second electromagnetic coil A1 and the first permanent magnet C is also due to the second electromagnetic coil A1 and the first permanent magnet C The direction of the magnetic field between the two is the same, the two magnetic fields repel each other, and the magnetic loop can not be formed by the outer ring yoke and the inner ring yoke, so the fourth induction coil is located between the two yokes. B3 also cannot generate induced current.

Due to the alternating magnetic field generated by the AC electromagnetic coil, the direction of the magnetic field running in the magnetic circuit of the outer ring yoke and the inner ring yoke is constantly changed, so that the magnetic field generated by the permanent magnet is in the inner ring yoke and the outer ring yoke. The magnetic circuit is continuously transformed into an alternating magnetic field, and the magnetic field generated by the electromagnetic coil constitutes a magnetic field loop, and an induction coil (output coil) disposed in the magnetic circuit generates an induced current through the alternating magnetic field, thereby increasing the current output intensity of the transformer. That is, increase the output power of the transformer.

In an application, the induction coil disposed on the inner or outer ring yoke may also be disposed on one side of the first and second electromagnetic coils or co-wound on the same core with the electromagnetic coil. Referring to Fig. 4 and Fig. 4-1, the induction coil B and the induction coil B1 are respectively disposed on one side of the first electromagnetic coil A and the second electromagnetic coil A1.

In application, the two annular yokes of the inner and outer rings may also have a square structure. Referring to FIG. 2 and FIG. 2-1, the magnetic circuit principle of FIG. 2 and FIG. 2-1 is the same as the magnetic circuit principle of FIG.

Referring to Fig. 2-2, the shaded portion of the square yoke is an orientation yoke made of a conductive magnetic material (such as oriented silicon steel or oriented silicon steel sheet), and each magnetic pole at each end of the permanent magnet is provided with a yoke on each magnetic pole. Two aligning yokes are respectively connected on both sides of the yoke, and the magnetic directions of the two aligning yokes connected to both sides of the yoke of each permanent magnet magnetic pole are the same as the magnetic field direction of the permanent magnet magnetic pole; The orientation yokes are respectively located at opposite positions on both sides of the yoke of the permanent magnet magnetic pole, and the magnetic directions of the two magnetic yokes are opposite at the same time. The arrow in Fig. 2-2 is connected to the magnetic yoke of the permanent magnet magnetic pole. The direction of magnetic conduction of the orientation yokes on both sides. Due to the single-guide magnetic property of the orientation yoke, when the first electromagnetic coil A is located on the outer square yoke and the magnetic pole is N pole, the first electromagnetic coil A can only pass the orientation yoke of the lower left and right portions of the inner and outer square yokes and the The two permanent magnets C1 form a magnetic field loop (Fig. 2), and the second electromagnetic coil A1 can only form a magnetic field loop through the orientation yoke of the upper right portion of the inner and outer square yokes and the first permanent magnet C (Fig. 2). When the first electromagnetic coil A is located at the magnetic pole S pole on the outer square yoke, the first electromagnetic coil A can only form the magnetic field loop through the orientation yoke of the upper left portion of the inner and outer square yokes and the first permanent magnet C (as shown in the figure). 2-1) At the same time, the second electromagnetic coil A1 can only form a magnetic field loop through the orientation yoke of the lower right portion of the inner and outer square yokes and the second permanent magnet C1 (see Fig. 2-1). Since the magnetic direction of the orientation yoke on both sides of the magnetic yoke on the magnetic poles at both ends of the permanent magnet is opposite in the entire square magnetic yoke magnetic circuit, the direction between the first electromagnetic coil A and the second electromagnetic coil A1 cannot pass through the inner and outer square yokes. The opposite orientation yoke constitutes a magnetic field loop, and the alternating magnetic field generated by the first electromagnetic coil A or the second electromagnetic coil A1 can only form a magnetic field loop between the first permanent magnet C or the second permanent magnet C1. In the application, the two ends of the soft magnetic core or the non-oriented yoke in the electromagnetic coil are respectively connected with two orientation yokes with different magnetic directions at the same time, and the magnetic direction and electromagnetic direction of one of the orientation yokes are respectively The direction of the magnetic field of the coil is the same, and the direction of the magnetic field of the other orientation yoke is opposite to the direction of the magnetic field of the electromagnetic coil. In the application, the magnetic yoke on the magnetic poles at both ends of the permanent magnet is a non-oriented yoke made of no magnetic material. In the application, the magnetic poles at each end of the permanent magnets may also be directly connected to the two orientation yokes whose magnetic flux direction is consistent with the magnetic field direction of the permanent magnet poles.

In application, the outer ring yoke and the inner ring yoke may also be polygonal.

In application, the inner ring yoke and the outer ring yoke may be square, or the inner ring yoke and the outer ring yoke may be circular, or the inner ring yoke may be a square outer ring yoke having a circular shape, or an inner ring. The yoke is a circular outer ring yoke having a square shape, or the inner ring yoke is a cross-shaped outer ring yoke having a circular shape, or the inner ring yoke is a cross-shaped outer ring yoke having a square shape, or The inner ring yoke and the outer ring yoke are both polygonal.

In the application, an air gap hole may be opened in the cross inner ring yoke.

In applications, the toroidal yoke can also be provided for multiple inner and outer rings.
