Abstract
The present invention relates to a rotating electric machine coated with an intumescent coating, wherein the intumescent coating has a homogeneous distribution throughout the surface of the substrate and a thickness corresponding to a value between 1% and 25%, preferably between 10% and 20% of the rotating electric machine housing wall thickness. The present invention further relates to an intumescent coating application method on a rotating electric machine.
Claims9
A coated rotating electric machine, comprising a substrate coated with intumescent coating.
A method for applying a coating to a rotating electric machine, the method comprising:
- i. providing one or more components of the rotating electric machine or an assembled rotating electric machine;
- ii. preparing one or more surfaces of at least one substrate of the rotating electric machine;
- iii. applying primers and/or adhesion promoters to the one or more surfaces of the at least one substrate surfaces of the rotating electric machine;
- iv. applying one or more protective layers comprising an intumescent coating onto the one or more surfaces of the at least one substrate of the rotating electric machine until the intumescent coating has a homogeneous distribution throughout the one or more surfaces of the at least one substrate and a thickness corresponding to a value between 1% and 25% or preferably between 10% and 20% of a rotating electric machine housing wall thickness;
- and
- v. curing the coated surfaces of the rotating electric machine substrate.
