  • Patent number: 10720802
    Abstract: The laminated core (12) comprises laminations (10), which are arranged one over the other and which are each connected to each other by means of a first connection (9, 15). In addition, at least some of the laminations (10) are connected to each other by means of a second connection (11). By using two connections, the advantages thereof can be bundled, whereby the number and/or size of the connection points can be reduced while the requirement for the laminated core (12) remains the same or very high requirements for the laminated core (12) can be met or even increased. Advantageously, an adhesive is used as one of the connections (11), while the other connection (9, 15) can be a form-fitting connection. The adhesive (11) is applied to the lower side (13) and/or upper side (14) of the laminations (10) before or after the punching of the laminations (10). However, the two connections can also be formed by two adhesive systems.

  • Patent number: 10700621
    Abstract: A method and apparatus for generating electricity by electromagnetic induction, using a magnetic field modulated by the formation, dissipation, and movement of vortices produced by a vortex material such as a type II superconductor. Magnetic field modulation occurs at the microscopic level, facilitating the production of high frequency electric power. Generator inductors are manufactured using microelectronic fabrication, in at least one dimension corresponding to the spacing of vortices. The vortex material fabrication method establishes the alignment of vortices and generator coils, permitting the electromagnetic induction of energy from many vortices into many coils simultaneously as a cumulative output of electricity. A thermoelectric cycle is used to convert heat energy into electricity.
