Electric Motor Winding Varnish

Cleaning and varnishing of machine windings.

Electric motor winding varnish.

Improved efficiency through better heat transfer improved mechanical winding design. Grainger s got your back. The varnishing method used in the repair process is important for efficiency and for the application of the electric motor or generator. Varnishing the windings of an electric motor or generator functions to insulate the windings from contaminants to make the windings rigid and tight and to dissipate heat.

The life of a winding depends upon keeping it in its original condition as long as possible. In a new machine the winding is snug in the slots and the insulation is fresh and flexible and has been treated to be resistant to the deteriorating effects of moisture and other foreign matter.

Choose a varnish with a dielectric strength that s greater than the voltage of the electrical equipment it protects. Spray these abrasion and wear resistant coatings on motor winding wire transformers and other metal electrical parts to protect them from oils chemicals and moisture. There are four types of varnishing methods that we will describe below. This insulation protects the windings from contamination shorting electrically and also make the windings more mechanically rigid.

The finest in insulating varnishes and impregnating resins ensure your electric motors generators transformers and sensors will function properly and reliably. Clear varnish leaves a transparent film so components can.
