Description

Technical field [0001] The invention relates to the field of generators, in particular to a positive and negative double-rotor permanent magnet generator. Background technique [0002] A permanent magnet generator generally includes a stator and a rotor. One of the stator or the rotor is composed of permanent magnets, and the other is provided with coil windings. Conventional permanent magnet generators generally use the rotor as a permanent magnet, and set coil windings in the stator. When the rotor rotates, the coil windings in the stator cut the magnetic lines of force, thereby inducing electromotive force in the coil windings to realize the conversion of mechanical energy into electrical energy. The existing permanent magnet generators have the following defects: 1) The stator winding can only cut the magnetic field lines on one side of the permanent magnet, and cannot fully exert the performance of the permanent magnet; 2) The conventional permanent magnet generators are mos...

AI Technical Summary

Problems solved by technology

Existing permanent magnet generators have the following defects: 1) The stator winding can only cut the magnetic force lines on one side of the permanent magnet, and cannot give full play to the performance of the permanent magnet; 2) Conventional permanent magnet generators are mostly driven by power mechanisms such as engines, It is not suitable for clean energy such as wind power or water power. The dedicated wind or water power generator is driven by the wind impeller or water conservancy impeller to rotate the rotor. When the wind or water conservancy is small, it is difficult to ensure the efficient operation of the generator; 3) In the existing permanent magnet power generation In the machine, when a certain part of the stator or rotor is damaged, the entire generator cannot be used, resulting in great waste; 4) In order to improve the efficiency of the existing permanent magnet generator, it is necessary to greatly increase the weight and volume of the generator, resulting in The cost of building and maintaining generators increases exponentially
