How to choose interlayer insulation materials for Customized electric motors? The electromagnetic coil of modern low-voltage electrical appliances only needs to choose high-strength enameled wire with stable quality, and strictly control the uniformity of the winding arrangement in the coil winding process, and control the pinhole degree, elasticity and breakdown of the electromagnetic wire itself. Performance indicators such as voltage and softening breakdown generally rely on the insulating layer of the enameled wire to meet the requirements of interlayer insulation, and there is no need to add an interlayer insulation gasket. ...
However, due to a certain voltage gradient between layers, and considering that the coil may be subjected to some complicated factors such as thermal stress, mechanical stress, electromagnetic force, and solvent vapor pressure during the working process, the insulation capacity of the coil may decrease. In order to improve the working stability and service life of the coil, there are still many coils that need to choose an appropriate film insulating material as the interlayer insulating liner. For the coils that need to be impregnated with insulating varnish, it is usually appropriate to choose insulating fiber film with strong lacquer liquid absorption as interlayer insulation to enhance the penetration of the dipping into the deep layer of the coil and increase the solid component of the impregnating varnish between the turns The amount of adsorption (the amount of paint hanging).
