Investigation of the deterioration of electric motor mica insulation coils

Investigation of the deterioration of electric motor mica insulation coils

We will conduct shape observation and elemental analysis of dust using an electron microscope equipped with an energy-dispersive X-ray analysis system!

We offer a "Deterioration Investigation of Electric Motor Mica Insulation Coils" by analyzing the presence of mica powder scattered due to wear to determine deterioration. Mica powder generated from the wear of mica tape due to the rotation and sliding of the coil scatters around the coil through gaps such as cracks and pinholes. By analyzing the dust around the equipment and checking for the presence of mica powder, we assess the deterioration of the insulation material. 【Characteristics of Mica】 ■ Excellent electrical insulation properties ■ Excellent heat resistance ■ The mica tape wears due to the rotation and sliding of the coil, leading to deterioration of the insulation material. *For more details, please download the PDF or feel free to contact us.

Ground-based infrared survey

Ground-based infrared survey

Captured the condition of the exterior wall with a higher surface temperature compared to normal areas using an infrared camera!

We would like to introduce infrared surveys from the ground. When exterior wall tiles and mortar are warmed by sunlight or outside temperatures, that heat is transmitted to the structure (thermal conduction). However, if there is delamination in the exterior wall tiles or mortar, creating an air layer, the heat does not transfer to the structure, resulting in a tendency for the surface temperature to be higher compared to normal areas. By capturing the state of the exterior wall with such temperature differences using an infrared camera, exterior wall diagnostics can be performed. 【Features】 ■ By capturing the state of the exterior wall with temperature differences using an infrared camera, exterior wall diagnostics can be performed. ■ It is effective when you want to understand the situation, even if roughly. *For more details, please download the PDF or feel free to contact us.
