Insulation Property

The insulating system of the electric motors focuses on the joining of several different insulating materials applied to the electrical components. This arrangement in an electric motor takes place through wire insulation enamel, impregnation varnish and resin, groove closure insulation, insulation between phases, groove bottom, bonding cable insulation and weld insulation .

However, components that do not spontaneously come in contact with the coil are not part of the insulation system and the properties of a product of any thermal class, we can not guarantee that each insulating material applied in its construction has the same capacity or class thermal.

The specification of an element belonging to a certain thermal class does not necessarily mean that each insulation material applied in its composition has the same thermal capacity. It should be remembered that the temperature limit for an insulation system should never be directly related to the thermal capacity of the materials used. It is good to verify that in any system, the thermal performance of an element can be optimized by the protective properties of certain materials used together with that material.
