Abstract

A rotor arresting device, a wind turbine and a method for arresting and/or rotating a rotor. The rotor arresting device comprises a rotor, a rotational assembly, and a static assembly fixed in position, comprising a toothed disk, which can be arranged on the rotational assembly, having a plurality of arresting recesses arranged along a circumference, wherein two adjacent arresting recesses form a tooth, a first arresting module having at least one first arresting element, a second arresting module having at least one second arresting element, wherein the first and the second arresting module can be arranged on the static assembly, wherein the first and the second arresting element are arranged and designed to engage in arresting recesses of the toothed disk, wherein the spacing of the first arresting element from the second arresting element in the circumferential direction of the toothed disk is a non-integral multiple of a tooth tip spacing of the toothed disk.
