20090269488 | VARNISH COMPOSITIONS FOR ELECTRICAL INSULATION AND METHOD OF USING THE SAME - A varnish composition for producing an electrically insulative thermoset coating is disclosed. The varnish composition includes a functionalized poly(phenylene ether) having at least one aliphatic unsaturated group and exhibiting an intrinsic viscosity in the range of about 0.06 to about 0.25 deciliter per gram, measured in chloroform at 25° C. The varnish composition further includes an unsaturated polyester resin or vinyl ester resin, a reactive liquid monomer, and a compatibilizing agent. When cured, the polymers and reactive liquid monomer form an electrically insulative thermoset. | 10-29-2009 |
20100080892 | VARNISH COMPOSITIONS FOR ELECTRICAL INSULATION AND METHOD OF USING THE SAME - A varnish composition for producing an electrically insulative thermoset coating is disclosed. The varnish composition comprises a functionalized poly(phenylene ether), an unsaturated polyester, and/or a vinylester resin. The varnish composition further comprises a reactive liquid monomer and a block copolymer comprising a poly(olefin) block, or a poly(diolefin) block, and at least one terminal poly(alkenyl aromatic) block comprising repeat units derived from an alkenyl aromatic monomer. When cured, the polymers and reactive liquid monomer forms an electrically insulative thermoset that provides superior crack resistance. | 04-01-2010 |
20100215844 | METHOD FOR FORMING STATOR COIL SURFACE COATING LAYER AND COATING MATERIAL INJECTION DEVICE - A nozzle for injecting a semiconductive coating material from the internal diameter side of a stator to the external diameter side of the stator is inserted in a core duct serving as an air flow passage between adjacent slots, and the semiconductive coating material is coated on the surface of the stator coil exposed to the air flow passage without drawing out the stator coil from the slot in the stator core to form a semiconductive coating layer, thereby repairing exfoliation of the semiconductive coating material on the surface of the stator coil. | 08-26-2010 |
20120107490 | METHOD AND PLANT FOR MANUFACTURING ELECTROTECHNICAL ARTICLES - The invention relates to the methods and the plant for manufacturing transformer windings. | 05-03-2012 |
20120183680 | METHOD OF FORMING A MOTOR WATERPROOF STRUCTURE - A method of forming a motor waterproof structure includes the steps of providing a motor stator assembly; using at least a first enclosing material to cover the whole motor stator assembly therein; using a second enclosing material to cover on an outer side of the first enclosing material, and leaving at least one opening on the second enclosing material to communicate the first enclosing material with an external environment; heating and curing the second enclosing material while bringing the first enclosing material to soften, melt and flow out of the cured second enclosing material via the at least one opening left thereon; and sealing the at least one opening on the second enclosing material. The motor waterproof structure formed with the method functions to protect the motor stator assembly against accumulated heat and has reduced forming cost and weight. | 07-19-2012 |
20120189768 | WATER-DISPERSIBLE VARNISH, ELECTRIC COMPRESSOR USING THE WATER-DISPERSIBLE VARNISH AND METHOD OF MANUFACTURING THE SAME, AND REFRIGERATION AND AIR-CONDITIONING APPARATUS EQUIPPED WITH THE ELECTRIC COMPRESSOR - To obtain water-dispersible varnish used in an alternative refrigerant/refrigerating machine oil refrigerant system or a natural refrigerant/refrigerating machine oil refrigerant system, the water-dispersible varnish being capable of solving two problems, namely, reducing the volatile components and the like during thermal curing and resistance of the cured varnish to the refrigerant system. | 07-26-2012 |
20130095232 | METHOD OF APPLYING VARNISH TO A STATOR - A method of applying varnish to a stator includes orienting a center axis of the stator substantially parallel to gravity, and orienting a crown end of stator windings upward and a weld end of the windings downward, relative to gravity. The crown end and the weld end of the stator are disposed on opposing sides of the core. The weld end is placed above a dip tank and varnish applied to the crown end of the windings with at least one nozzle. The nozzle is controlled along a first direction and a second direction, which are perpendicular to the center axis. The varnish substantially coats the crown end of the windings, runs through the slots, and drips from the weld end of the windings into the dip tank. The dip tank is raised to submerse the weld end of the windings but not the core. | 04-18-2013 |
