Definitions
- the assembled stator comprising the wound wiring and electrical insulation parts is then impregnated with a thermoset varnish or matrix resin to fill as much of the open space in the slots as possible to reduce dielectric breakdown due to air voids.
- a refurbisher must thermally decompose, i.e., burn off, all of the organic components, including the varnish and/or matrix resin, and electrical insulation.
- the electrical insulation parts in the electrical device component assembly are made from laminate material comprising a film and nonwoven sheets, in which at least from one side the film is thermally bonded to the nonwoven having a thermoplastic material that softens when heated, the electrical device components will only require heating up to some softening point of the thermoplastic material to weaken the structure and allow the electrical conductor winding to be removed from the slots.
- the laminate electrical insulation parts can be used in electrical devices in many different forms. These laminate electrical parts function as electrical insulation, aid for the wire insertion in the slots, fixture of the wiring in the slots, and mechanical protection of the wiring.
- Two of the most common electrical device components with slots are rotors and stators.
- Figure 1 is an illustration of one such device 1 having slots 2. If this electrical device component is stationary in the electrical device it is called a stator; if this electrical device component rotates it is called a rotor.
- Coefficient of friction of the laminate surface was measured in accordance with ASTM D-1894 using Instron Coefficient of Friction Fixture with the polished stainless steel friction table with the maximum roughness depth of 37 microinches (0.9 micrometers). Breakdown voltage of laminates was measured in accordance with ASTM D149-97a, Method A (short time test) using flat 51 mm diameter and 25 mm thick electrodes with edges rounded to 6.4 mm.
