More Information
Summary:The invention relates to an impregnation device (1) for trickle impregnation of a stator (2) of an electric machine with a synthetic resin (19) which cures under an increase in temperature, the stator having a hollow cylindrical stator core (3) and at least one winding (4), a drive shaft (7) being arranged coaxially inside the stator (2) and being drivable by a drive motor (6), at least one holding device (8, 9) being arranged on the drive shaft, by means of which holding device the stator (2) can be detachably connected to the drive shaft (7), wherein a trickle device (35) is provided by means of which the synthetic resin (19) can be directed onto at least one axial end of the winding (4) of the stator (2), wherein a heating device (36) is provided, by means of which the winding (4) and the stator core (3) can be heated to a trickle temperature, and the heating device (36) having at least one electromagnetic inductor (14) which is arranged so as to be movable coaxially or axially parallel to the stator (2).
