Abstract
The invention relates to an impregnation device () for trickle impregnation of a stator () or armature of an electric machine with a synthetic resin () curing under temperature increase, comprising a holding device () which can be tilted vertically relative to the horizontal () and to which a drive motor () is attached as a rotary drive for the stator () or the armature, a drive shaft () operatively connected to the drive motor (), a clamping device () which is non-rotatably connected to the drive shaft () and capable of detachably connecting the stator () or the armature to the drive shaft (), a trickle device () capable of applying a synthetic resin () onto at least one axial end of the windings () of the stator () or the armature, and a heating device capable of heating the windings () of the stator () or the armature to a trickle temperature and to a comparatively higher curing temperature. The heating device according to the invention comprises an electromagnetic inductor () which is arranged coaxially or axially parallel to the stator () or the armature. The invention also relates to a production plant () for the trickle impregnation of a stator () or armature, in which this impregnation device () is integrated.
