Abstract
An improved magnetic generator has been developed that is particularly suitable for creating modular micro wind turbines, although other power generation applications are contemplated. The generator utilizes a series of rotors with axially aligned magnets on each side of the rotor face. As a drive shaft rotates the rotors in proximity to stators, a magnetic flux and electricity is generated. In certain embodiments, the rotors utilize magnet pockets to stabilize the magnets. In the preferred embodiments, layers of magnets are placed in each magnet pocket to achieve magnetic amplification by having multiple magnets, and their respective fluxes, influence the stators.
Claims20
An electric generator comprising:
- a. a drive shaft;
- and
- b. a series of alternating stators and rotors configured along said drive shaft, said series of rotors comprising an initial rotor, a first main rotor, and a second main rotor, and said series of stators comprising a first stator between said initial rotor and first main rotor, and a second stator between said first main rotor and second main rotor, and wherein said first and second main rotors comprise a plurality of axially aligned opposite magnet pockets on each side of the first and second main rotors, each of the opposite magnet pockets containing at least one axially aligned magnet, and wherein the at least one axially aligned magnet in each of the magnet pockets are oriented such that opposing magnetic poles face each other, wherein the two axially aligned magnets of the first main rotor and the two axially aligned magnets of the second main rotor create a magnetic flux in the second stator when rotated about the drive shaft.
An improved magnetic rotator assembly, comprising:
- a. a circular rotor having a plurality of magnet pockets radially arranged on each face of the circular rotor and a central drive shaft bore;
- b. a drive shaft extending through the central drive shaft bore;
- and
- c. a plurality of magnets, wherein magnets are seated in said magnet pockets on each face of the circular rotor in a first layer on each face so that the polarity of each magnet is opposite the polarity of the opposite magnet at both ends of the magnet.
An improved magnetic generator core, comprising:
- a. a central housing with a hollow interior;
- b. a drive shaft extending through the interior of the central housing;
- c. multiple magnetic rotor assemblies located within the housing around the drive shaft, where each rotor assembly comprises, a circular rotor having a first face and a second face, said first and second circular rotor faces each having a plurality of radially arranged magnets forming a first layer and a second layer of magnets on each face, so that the polarity of each magnet is opposite the polarity of the opposite magnet at both ends of the magnet;
- and
- d. at least one stator disposed between the rotor assemblies.
