A stator of a directly driven wind turbine generator includes a stator support, and stator segments arranged around a circumference and positioned on flanges of the stator support. Each stator segment includes a segment support having a cavity. Securing devices secure the stator segments via the segment supports to the flanges of the stator support. The securing devices have each an intermediate piece to complement the cavity of a corresponding one of the segment supports, and an alignment pin to secure the intermediate piece in position and to adjust an air gap of the wind turbine generator.

Securing of stator segments

A stator of a directly driven wind power generator includes a stator support including flanges with bores and stator segments positioned on the flanges, when viewed in a circumferential direction. Each stator segment includes a segment support having recesses. At least two securing devices for each of the stator segments secure the stator segment to the flanges. Each securing device includes a bore part insertable in a corresponding one of the recesses, a shim, and an alignment pin insertable in a corresponding one of the bores of the flanges, so that the stator segment is positioned and secured vertically via the bore part and the alignment pin and via the shim to thereby realize a uniform air gap between the stator and a rotor of the wind power generator.
