Definitions
- the invention relates to a current generator for generating electrical current from different energy sources such as wind, water, steam according to the preamble of claim 1.
- a wind generator which consists of a first propeller, a first rotor of a first power generator driven by the latter, a second rotor which surrounds the first rotor, and a second propeller which is on the opposite side to the first propeller of the generator is arranged, drives the second rotor and rotates and rotates the second rotor opposite to the first propeller.
- a second generator is located between the second rotor and a housing fixed to the device, the rotor of which is firmly connected to the second rotor on the outside thereof and the stator of which is firmly connected to the housing.
- Both the first rotor and the second rotor consist of electromagnets.
- the current supplied by the second generator is conducted into the windings of the electromagnets of the first or of the second rotor of the first current generator.
- the object of the invention is to develop a power generator with which the disadvantages of the prior art described are avoided and with which a broad application is possible both in wind power plants and in all types of power plants, in aircraft or in the automotive industry and which is simple Retrofitting existing systems with simple means.
- the power generator consisting of a shaft of a rotor of a first power generator, a rotor component with inner and outer windings or magnets, which surrounds the first rotor and carries both the second rotor of the first power generator and the rotor of a second power generator, which Surrounding the stator of the second current generator is characterized in that the shaft is designed as a continuous shaft, on which at least one gear is additionally arranged, via which the rotor component is displaced in the opposite direction of rotation.
- the power generator is versatile and can be used regardless of the type of energy generation, including in the automotive and aircraft industries. The energy is conducted on one or two sides with the same direction and speed to the continuous shaft of the first rotor, which drives this rotor and a gear attached to the shaft, which rotates the rotor component in opposite directions.
- the energy is introduced into the generator on two sides with the same direction and variable speed on a separate shaft, one shaft carrying the rotor and a gearbox for driving the rotor component attached to the other shaft.
- FIG. 1 is a schematic sectional view of an embodiment of the power generator according to the invention.
- FIG. 2 a schematic axial section through the housing of the embodiment of the current generator according to FIG. 1, 3 shows a schematic sectional illustration of an embodiment variant 1 of the arrangement of generator coils and magnets,
- Fig. 4 is a 'schematic sectional view of an embodiment 2 of the arrangement of generator coil and magnet
- Fig. 6 a schematic sectional view through the housing of a further embodiment of the power generator according to the invention.
- the current generator consists of a housing 1.
- a continuous shaft 2 is mounted in the housing 1, with which a first rotor 3 and at least one gear 4 are firmly connected.
- two gears 4 have been designed to represent the possibilities of the arrangement on one or both sides, only one gear, optionally arranged on one shaft end, being required for the function.
- a rotor component 5 with inner windings or permanent magnets 6 and outer windings or permanent magnets 7 is movably mounted on the shaft 2 and acts with its inner winding 6 as a stator for the first rotor 3.
- the first rotor 3 and the inner winding or permanent magnet 6 of Rotor component 5 together form a first current generator.
- Permanent magnets or generator windings 8 are firmly connected to the housing 1.
- the housing 1 with the permanent magnets or generator windings 8 forms a second stator and together with the outer windings or permanent magnets 7 of the rotor component 5 a second current generator.
- the direction of rotation of the rotor component 5 is set in the opposite direction to the shaft 2 with the first rotor 3 fixedly arranged thereon, so that the two current generators work at a high relative speed of their parts.
- the gear 4 is designed here as a planetary gear, but can have another expedient embodiment depending on the application. It ensures a translation of at least 1: 3.
- the advantage is the one-sided introduction of energy onto a continuous shaft 2 with a high relative speed of the generator parts and a high current yield, the type of generation of the introduced energy being arbitrary, wind power, nuclear energy, hydropower and the like.
- the energy input to the shaft 2 can also be carried out on both sides with the same direction and defined speed, which applications e.g. enabled or facilitated in hydropower plants and automobiles.
- the rotor component 5 carries on the inside an electromagnet 6 which forms the first current generator with the rotor 3, and on the outside a generator winding 7 which forms the second current generator with permanent magnets 8 fastened to the housing 1.
- the current generated in the generator winding 7 is conducted into the electromagnet 6, so that stronger and long-term stable fields can be generated here compared to permanent magnets, without the need for a current supply from outside the generator.
- the rotor component 5 carries on the inside an electromagnet 6 which forms the first current generator with the rotor 3, and on the outside permanent magnets 7 which forms the second current generator with the generator winding 8 fastened to the housing 1.
- the current generated in the generator winding 8 is conducted into the electromagnet 6, so that stronger and long-term stable fields can be generated here compared to permanent magnets, without the need for a power supply from outside the generator.
- the second power generator can be operated as an electric motor in order to overcome the moments of inertia of the rotor component 5 and gear 4 (FIG. 2) in the start-up phase by supplying power from outside the generator.
- the rotor component 5 carries inside permanent magnets 6, which form the first current generator with the rotor 3, and also outside permanent magnets 7, which forms the second current generator with the generator winding 8 attached to the housing 1. Furthermore, the second power generator can be operated as an electric motor in order to overcome the moments of inertia of the rotor component 5 and the gear 4 (FIG. 2) in the start-up phase by supplying power from outside the generator.
- the energy is introduced on two sides with the same direction and variable speed on two shafts 2a and 2b, one shaft 2a carrying the rotor 3 and the other shaft 2b carrying the gear 4 which holds the rotor component 5 in opposite rotation offset. This embodiment enables applications, for example in automobiles.
