1. An impregnation plant for axial symmetrical components of electric motors, said plant having a plurality of work stations and modules managed and controlled through a central processing unit, said plant comprising:
at least one fixed support frame;
one or more fixed heating stations, which are arranged to heat each component to a predefined temperature;
one or more impregnation modules, which are arranged to cover at least part of each component with an impregnating substance; and
one or more transport and loading/unloading modules, which are arranged to transfer said components from and toward said one or more fixed heating stations,
wherein said fixed support frame is provided with one or more handling and guiding means, wherein said one or more impregnation modules and said one or more transport and loading/unloading modules are mounted on said one or more handling and guiding means in a movable manner, and wherein said one or more handling and guiding means are arranged to selectively receive, in a removable manner, one or more further movable work modules comprised in said impregnation plant,
wherein each of the one or more fixed heating stations is provided with one or more motorized support devices for supporting said components, each of the one or more fixed heating stations being arranged to impart both a rotary movement, through said one or more motorized support devices and in both directions of rotation around a predefined rotation axis, and a tilting movement, with respect to a predefined plane, on each component mounted on its respective support device, wherein said handling and guiding means comprise one or more upper sliding guides, positioned on said fixed support frame at an upper end of said fixed support frame, and one or more lower sliding guides, positioned on said fixed support frame at a rest surface,
wherein each of the one or more impregnation modules moves along said upper sliding guides and is electrically controlled, through said central processing unit, to selectively move and position in front of each of the one or more fixed heating stations in the moment when the impregnation of said components is performed, and
wherein each of the one or more transport and loading/unloading modules rests and moves along said lower sliding guides and is electrically controlled, through said central processing unit, to selectively move and position in front of each of the one or more fixed heating stations.
