Abstract

A bearing (200) for adjusting an angle of attack of a rotor blade (220) of a wind turbine according to an exemplary embodiment, comprising a first bearing ring (230) and a second bearing ring (240), wherein the first (230) and the second bearing ring (240) are rotatable relative to each other, wherein the first bearing ring (230) comprises, as a slider or translator of a linear motor (100), a plurality (350) of magnetic field sources (110) disposed adjacently around at least a part of its circumference, wherein the magnetic field sources (110) are formed such that each two adjacently disposed magnetic field sources (110) generate a magnetic field with alternating polarity, and wherein the second bearing ring (230) comprises, as a stator of a linear motor (100), a group (190) of at least two coils (170) disposed adjacently around at least part of its circumference. Fig. 4.
