Abstract
For impregnating stators in mass production, a device includes holders with at least one rolling surface and unit components of an impregnation unit with a rolling device, on which the holders with clamped-in stators or, even in the case of stators with a cylindrical outer surface suitable as a rolling surface, the stators themselves lie purely as a result of gravity.

A trickle unit for the trickle impregnation of stators comprising:
- a trickle device having a trickle region;
- a gelling device having a gelling region;
- and
- a transport device for transporting the stators from the trickle device to the gelling device with a plurality of holders for holding, turning, and transporting a stator in during an impregnation of the stator with resin, wherein each holder of the plurality of holders has a clamping device for clamping in the stator and at least one rolling surface for rolling support of a rotating holder with a clamped-in stator, wherein each holder of the plurality of holders comprises a cage which surrounds the clamped-in stator,
- wherein the transport device includes a circulating system configured to cycle the stators clamped into the holders of the plurality of holders from the trickle region into the gelling region and the stators are rotated at least between the trickle region and the gelling region, or wherein the transport device includes a handling unit having a robot arm, or both.
A method for the trickle impregnation of a plurality of stator each provided with a winding, the method comprising:
- providing a holder for each stator, the holder having a clamping device for clamping in the respective stator and at least one rolling surface for rolling support of the rotating holder with a clamped-in-stator and which comprises a cage which surrounds the clamped-in-stator;
- clamping the respective stator into the clamping device, wherein each stator is held for trickling and gelling in a dedicated holder;
- performing a trickling and a gelling on the stators which are held on the holders, wherein the holders roll over the at least one rolling surface in order to rotate the stators;
- and,
- transporting the stator from the trickling to the gelling so that a station is released for a next stator in such a way that trickling and gelling occur at the same time.
