Innovative high-performance insulation material for electric motors
The present invention relates to a new method of coating copper conductors of electric motors, which not only protects them by ensuring optimal electromagnetic insulation, but also provides them with high resistance both chemically, e.g., against corrosion, and thermally up to even temperatures above 600°C
At the state of the art, to protect and thus insulate the electromagnetic components of a motor, i.e., the copper-based conductors, materials with very low radiation and high temperature resistance characteristics are usually used, causing their deterioration and rapid loss of insulating properties and limiting the temperature range within which an electric motor can operate; very durable and high-performance ceramic enamels are also used, but they require complex construction and installation processes.
Therefore, a new methodology is proposed for the production and use of ceramic insulating coatings based on filled silicone resins, which can be easily adopted to effectively and efficiently electrically insulate copper conductors of electric motors and increase their operating temperature up to 600°.
