  • Magnetic rack-and-pinion coupling system and sea wave energy conversion system
    Patent number: 11159081
    Abstract: The present disclosure refers to a magnetic rack-and-pinion coupling system (1) for contactless transfer of kinetic energy comprising: a rack component (3) comprising a first pattern of ferromagnetic structure being repetitive along a rack length axis (L), and a pinion stack component (5) being rotatable about a rotor axis (R), wherein the rack component (3) and/or the pinion stack component (5) are movable relative to each other along the rack length axis (L), and wherein the pinion stack component (5) comprises a stack of pinion discs (9a,b,c,d) each comprising a second pattern of ferromagnetic structure being repetitive along a circumference of the respective pinion disc (9a,b,c,d), wherein at least one magnetic field producing element (13a,b,c) is sandwiched between neighbouring pinion discs (9a,b,c,d), wherein each magnetic field producing element (13a,b,c) has one magnetic pole (N, S) at an axial front side (14) of the magnetic field producing element (13a,b,c) and the other magnetic pole (S, N) at
