Problems solved by technology
The turntable permanent magnet generator adopts a turntable made of non-magnetic material, which has less reaction to the armature and less influence on the main magnetic field and speed. On the one hand, the N.S magnetic pole cross-section is not large, the two magnetic pole cross-sections have different sizes, and there is a shortage of small output power. In addition, the magnetic pole cross-sectional area of the yoke is large, the copper wire consumption of the coil is large, and the resistance is also large.

Embodiment Construction
[0009] in figure 1 , 2 In the embodiment shown, a piece of iron core 2 is connected in the housing 1 as a bar-shaped cylindrical body, the barrel wall bar of the iron core 2 is a long magnetic pole, and the coil 3 is mounted on the long magnetic pole, corresponding to the radial surface of the long magnetic pole A cylindrical permanent magnet 7 with two NS poles arranged side by side is arranged at the position of, and the permanent magnet 7 is mounted on the shaft 6. A rotating drum 4 is movably connected to the shaft 6 between the long magnetic pole and the permanent magnet 7. The drum 4-2 is connected to the wall of the cylinder 4-1 made of non-magnetic material. The two ends of the cylinder 4-1 are connected to the two end plates 4-3, and a gear 4-4 is connected to one end plate 4-3. The two rows of misaligned magnetic conductors 4-2 on the cylinder 4-1 correspond to the positions of the N and S magnetic poles on the permanent magnet 7. The size and number of the N.S magne...

The invention discloses a drum permanent-magnet generator which is high in generating efficiency, high in output power and low in copper loss. The drum permanent-magnet generator comprises a shell, an iron core, a coil, a drum, a permanent magnet, a shaft, an end cover, a shaft seat and a base, wherein the drum comprises a cylinder, a magnet, two end plates and gears; the iron core is connected inside the shell; the iron core is provided with a long magnetic pole; the coil is arranged on the long magnetic pole; a magnetic pole N and a magnetic pole S which are side by side of a cylindrical permanent magnet are arranged at the corresponding positions of the radial surface of the long magnetic pole; the permanent magnet is arranged on the shaft; the drum is arranged between the long magnetic pole and the permanent magnet and is connected with the shaft; two rows of staggered magnets and the two end plates connected to the cylinder are made of non-magnetic materials; each end plate is connected with a gear; the positions of the two rows of staggered magnets on the cylinder are opposite to the positions of the magnetic pole N and the magnetic pole S of the permanent magnet; the end cover is arranged on the shell; the shaft is arranged on the shaft seat; and the shell and the shaft seat are arranged on the base. The drum permanent-magnet generator does not have a rotor; the conventional rotor is replaced by the drum made of plastics and the magnet; and the drum permanent-magnet generator is light in weight, high in generating efficiency, energy-saving and low in generating cost.
Description
Technical field [0001] The invention relates to a permanent magnet power generation device, in particular a rotating drum permanent magnet generator with high power generation efficiency, high power and low copper consumption. Background technique [0002] The present invention is an improved invention based on the ZL201010567262.8 turntable permanent magnet generator invented by me. The turntable permanent magnet generator adopts the turntable made of non-magnetic material, which has little response to the armature, and has little effect on the main magnetic field and speed. The light weight of the turntable has high power generation efficiency, but its two large and small magnets are arranged in a circular section. Above, the NS magnetic pole section is not large, the two magnetic pole cross sections are large and small, and the output power is small. In addition, the yoke pole cross section area is large, the coil copper wire is consumed more, and the resistance is also large....
