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 linear 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 linear 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 disc (13a,b,c) is sandwiched between neighbouring pinion discs (9a,b,c,d), wherein each magnetic disc (13a,b,c) is permanently magnetic with one magnetic pole (N, S) at an axial front side (14) of the magnetic disc (13a,b,c) and the other magnetic pole (S, N) at an axial end side (16) of the magnetic disc (13a,b,c).
