Abstract
A stator ring for an electric generator having a plurality of grooves for receiving the stator winding, and a magnetic yoke. A stator ring which has a plurality of cooling recesses through which cooling air can flow in the region of the magnetic yoke, wherein the stator ring has a plurality of stator plates which are stacked in succession in the axial direction of the stator ring, wherein the cooling recesses extend through all stator plates.
Claims17
A stator ring for an electric generator, of a wind turbine comprising:
- a plurality of grooves for receiving the stator winding;
- and
- a magnetic yoke,
- wherein the stator ring in a region of the magnetic yoke has a plurality of cooling recesses through which cooling air is able flow, wherein the stator ring has a plurality of stator plates stacked in succession in an axial direction of the stator ring, wherein the plurality of cooling recesses extend through all of the plurality of stator plates, and wherein each surface of the plurality of cooling recesses is of such a contour that production of turbulence within the plurality of cooling recesses is promoted.
(canceled)
An electric generator of a wind turbine the electric generator comprising:
- a rotor and a stator, wherein the stator has a stator ring, wherein the stator ring includes:
- a plurality of grooves for receiving the stator winding;
- and
- a magnetic yoke,
- wherein, in a region of the magnetic yoke, the stator ring has a plurality of cooling recesses through which cooling air is able flow, wherein the stator ring has a plurality of stator plates stacked in succession in an axial direction of the stator ring, wherein the plurality of cooling recesses extend through all of the plurality of stator plates, and wherein each surface of the plurality of cooling recesses is of such a contour to promote turbulent air flow of the cooling air.
