Insulating Varnish For Electric Motors

The cement is also available in powder form known as.

Insulating varnish for electric motors.

About product and suppliers. This insulation protects the windings from contamination shorting electrically and also make the windings more mechanically rigid. Slot insulation and wedge. Jyoti 141 fd an electric insulating air drying varnish based on modified polyester resin.

The old dip and bake in varnish method of insulating motors is replaced by the vpi process for specific reasons. Sauereisen electric resistor cement no. 78 is an ideal electrical refractory cement for coating resistors coils electric heating elements furnaces and embedding resistance wire. Cleaning and varnishing of machine windings.

Electrical insulating varnish. They are solvent based so they dry quickly. L armatures l generators l transformers l standard motors. 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.

After a motor is rewound the windings must be further insulated with resin or varnish. From environmental protection moisture and dust to added strength varnish and resin support proper motor function and help prevent motor system failure. Applications usages the 4228 insulates transformers coils armature motor windings and various electric. The finest in insulating varnishes and impregnating resins ensure your electric motors generators transformers and sensors will function properly and reliably.

Dip and bake epoxy varnishing trickle varnishing vacuum pressure impregnation and. Vpi vacuum pressure impregnation is a process that is a technological step forward from varnishing electric motors. In electrical machines jyoti 141 fd used both for manufacturing and repairing the following thermal class h 195 objects. There are four types of varnishing methods that we will describe below.

Improved efficiency through better heat transfer improved mechanical winding design. This low viscosity one part varnish coating is easy to use and adheres well to many substrates. 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.
