Motor winding varnishing and VPI process
source：未知 time：2024-11-06 09:22nbsp; click：
Winding varnishing is an important and key process in motor manufacturing. The heat resistance and thermal conductivity of winding insulation can be improved by varnishing. Before varnishing, the gaps in the winding insulation are filled with air, and the thermal conductivity is poor. After varnishing, the insulating varnish fills all the gaps in the winding insulation, and the thermal conductivity is greatly enhanced. After the paint film is formed, it can reduce contact with air, delay oxidation, and improve heat resistance.
