Abstract
The present application relates to a slot wedge element, a stator device, a motor, and a wind turbine. The slot wedge element extends in a first direction and has opposite first and second edges has a first surface and a second surface in the thickness direction thereof, and is attached to a winding of the stator device via the first surface. The second surface includes a first portion, a second portion, and a third portion sequentially distributed in the first direction. A second thickness between the second portion and the first surface is greater than a first thickness between the first portion and the first surface, and the second thickness is greater than or equal to a third thickness between the third portion and the first surface. The first thickness is decreasingly distributed in a direction from the second portion to the first edge.
