Insulation paper used in motor winding. Insulating papers ar inserted in motor winding just to seperate each of the winding coil from another Thus the windings of the motor will not get shorted to each other because lots of parameters like voltage rating current carring capacity depends upon the number of windings. So thats why making insulated by each other is necessary. 10 Zeilen 36644 DM insulation paper application.
6644 DM insulation material is used in low-voltage. Therefore an extra insulation layer using paper strip is used between windings layers. However if you are wondering why paper in particular is used for insulation and simply the answer is that the.
Nomex paper is compatible with all classes of varnishes and adhesives transformer fluids lubricating oils automatic transmission fluids ATFs and refrigerants. Typical Applications in Motors. Nomex papers and Nomex based laminates are used in motors as.
Slot liners Wedges and midsticks Phase insulation Conductor insulation. Ultra-Seal Winding is an alternative method of insulating a motors windings. Ultra-Sealed windings are completely impregnated and seals the coils with high molecular weight thermoset polymer resin.
This allows for total protection against moisture contaminants and more efficient cooling. We recommend Ultra-Seal Windings for motors found in extreme environments where contamination is likely. Want to learn more about Ultra-Seal.
You may see the use of a temperature rise letter used along with the insulation class such as an FB motor. The F refers to the insulation class for the windings while the B refers to an 80C rise the maximum temperature rise for Class B is 80C. This type of notation is becoming more widespread because many motors use Class F insulation and there is a reason for that.
Lets go back to the FB motor. Its rated for a maximum winding. The correct insulation of the winding of a motor is determined by both the temperature rise in the motor and the temperature of the ambient air.
If a motor is subjected to an ambient temperature higher than 40 o C it must normally be de-rated or a higher insulation class of material used. Cotton Silk Paper cellulose wood etc neither impregnated nor immersed in oil it is unsuitable for electrical machines and apparatus. In this insulation materials or combinations of materials such as cotton silk and paper when suitably impregnated or coated when immersed in a dielectric liquid such as oil.
Other materials or combinations of materials may be included in this class if by. The common types of insulating materials in use for electric motors are E and B for small motors and F for medium sized and large ones. General industrial practice however is to limit the temperature to class B limits even if class F insulation is used.
Insulation class A previously in use has been discontinued in view of its low working temperature. 11 Zeilen The electrical insulation system for wires used in generators electric motors transformers. Type Of Motor Winding Connection.

NEMA motor insulation classes describes the ability of motor insulation in the windings to handle heat. There are four insulation classes in use namely. A B F and H.
All four classes identify the allowable temperature rise from an ambient temperature of 40 C 104 F. Classes B and F are the most common in many applications. Insulation Papers and Films are paper materials used for electrical insulation in applications such as wedges coils motors and more.
Insulation Papers and Films offer thermal stability and conductivity low moisture absorption high varnish absorption while remaining cost-effective.
