Embodiment 1

[0034] A linear generator such as Figure 1-9 As shown, it includes the primary and the secondary; the primary includes the primary yoke 1, the permanent magnet array and the coil 6, the primary yoke is a U-shaped rectangular parallelepiped structure, the center of the bottom is provided with a primary raised part 5, and the coil is wound on the raised part On the top, a ring-shaped large coil is formed, and two permanent magnet arrays 3 are arranged on both sides of the U shape. The permanent magnets in the permanent magnet array on each side are arranged alternately and evenly with N and S poles, that is, the pole pitch between the permanent magnets They are all the same, the polarity of the permanent magnets at the corresponding positions on both sides is the same, the permanent magnets on both sides are arranged symmetrically, and the magnetization direction of the permanent magnets is the horizontal direction; Made of magnetically permeable material, the secondary include...

Embodiment 2

[0037] A linear generator such as Figure 10 As shown, the difference from the first embodiment is that the secondary teeth 7 at the corresponding positions at both ends of the secondary are staggered by half the pole pitch (the pole pitch is at figure 1 It has been marked in , which is the width of the permanent magnet plus the distance between adjacent permanent magnets, and the pitch of the secondary teeth is the width of the secondary teeth plus the distance between adjacent secondary teeth), from figure 1 It can be seen in the figure that the two first secondary teeth on the left and right sides of the front end of the secondary yoke 8 are staggered by half the pole pitch in the length direction of the secondary yoke. This setting can minimize the reluctance fluctuation force. Magnetic resistance is the electromagnetic force that exists between the permanent magnet and the mover core when the winding is not energized or disconnected. In the direction of motion, this magne...

Embodiment 3

[0040] A linear generator such as Figure 12 As shown, the difference from the first embodiment is that the two coils are respectively wound on both sides of the primary raised portion 5 at the bottom of the primary yoke 1 , or on the two sides of the primary yoke, and the others are the same as the first embodiment.

[0041] During the reciprocating movement of the secondary under the action of external power, when the secondary teeth 7 are aligned with the poles of the permanent magnet, the magnetic circuit passes through the secondary teeth, the secondary yoke 8, the first air gap 9, the primary raised part, Primary yoke, permanent magnet, and second air gap 10; when the secondary teeth straddle the two primary permanent magnets, the magnetic circuit is in the longitudinal direction, and the secondary teeth form a closed loop with the magnetic field of the adjacent two permanent magnets; when again, When the secondary teeth are aligned with the poles of the permanent magnet...

Abstract

The invention discloses a linear generator, and the linear generator comprises a primary side and a secondary side; the primary side comprises a primary yoke, a coil and at least one permanent magnetarray; N and S poles of permanent magnets in the permanent magnet array are alternately and uniformly arranged; the primary yoke is provided with a primary convex part, and the coil is sleeved on theprimary convex part or the primary yoke; the permanent magnet array is arranged on the primary yoke; the secondary comprises a secondary yoke and secondary teeth; the secondary teeth are of flat-plate-shaped and uniformly-toothed finger-shaped structures, the tooth pitch of the secondary teeth is equal to non-zero even-number times of the polar pitch of the permanent magnet, and a gap exists between the secondary yoke and the primary protruding part and is a first air gap; the permanent magnet array and the secondary teeth are arranged on the same plane or the whole column of permanent magnetsare arranged below the secondary teeth, and a gap exists between the permanent magnet array and the secondary teeth and is a second air gap; the secondary teeth move on a plane, so a current is generated in the coil through changes of a magnetic circuit and magnetic flux. The invention provides the novel linear generator which is small in size and simple in structure.

Description

technical field [0001] The invention relates to the field of generators, in particular to a linear generator. Background technique [0002] Conventional linear generators are composed of primary coils and secondary permanent magnets. The primary is composed of multiple sets of coils. At the same time, permanent magnets with opposite polarities are arranged alternately on the secondary. Rotating or linear motion under normal circumstances will inevitably lead to complex motor structure, and the secondary needs large power during motion, and the energy consumption required to generate current is high; due to the length limitation of the cogging distance of the coil winding, it is difficult to make the size of the conventional linear generator to very small. Contents of the invention [0003] The purpose of the present invention is to provide a new type of linear generator with small volume and simple structure to overcome the disadvantages of relatively complicated structur...
