Below in conjunction with accompanying drawing the embodiment of the utility model is described.
The round induction synchrometer that constitutes by aluminium base, metallic conductor winding etc.; Traditional handicraft all needs on the conductor group of the rotor surface of round induction synchrometer, to cover a mylar as insulation course; On this insulation course, cover an aluminium foil subsequently again as screen layer; This technology can be eliminated the coupling capacitance of round induction synchrometer, plays the effect that improves the product precision.But mylar and aluminium foil on this technology lower rotor part surface conductor group have air in twos at it between interlayer, this makes that under vacuum environment the air between interlayer can make mylar and aluminium foil outwards bloat, thereby makes product to use.This paper proposes a kind of brand-new process means; Through applying colloidal state epoxy resin as insulation course at rotor surface; Eliminate the air between interlayer in twos in the mode of plating conducting film on the insulation course more subsequently, make that round induction synchrometer can be in normal use under the vacuum environment.
As shown in Figure 1, the utility model is a kind of round induction synchrometer, comprises stator substrate 1, rotor substrate 2, stator metallic conductor zone 3, rotor metallic conductor zone 4, insulation course 5, screen layer 6.
As shown in Figure 3, the rotor winding on the rotor metallic conductor zone 4 is made continous way, and it is formed by connecting through conductor inner end 8 and conductor outer end 9 many active conductors 7, and the number of definition active conductor is the number of poles of round induction synchrometer.
After the rotor winding machined, the insulating epoxy glue that debugging is good was coated on the winding surface, places it in vacuum tank, and the vacuum tightness of its vacuum tank is adjusted to and is not higher than 1X10
-2Handkerchief vacuumized 20 minutes.Subsequently rotor is placed in the temperature control box its 60 degrees centigrade were solidified 2 hours.The surface of the rotor after epoxy glue solidified is handled smooth with the mode of turning or polishing, the solid-state epoxy layer thickness after the processing is not more than 0.05mm, and flatness is not less than 0.01mm, and this epoxy layer is the insulation course of rotor.Rotor is taken under the coating machine subsequently again plated film is carried out on its surface, the material of plated film needs conductive materials such as aluminium, silver, copper, and this coatings is the screen layer of rotor.
