FIELD: electrical engineering; insulating materials for wires or commutators of electrical machines. ^ SUBSTANCE: proposed mica base insulating material has mica paper layer, backing of inorganic fiber (glass or basalt), and binders, such as betulinic and adipic acids having molecular mass of 10 000 to 15 000. Such binders of desired molecular mass can be easily produced. ^ EFFECT: enhanced mechanical strength, heat resistance, and flexibility; facilitated manufacture. ^ 1 cl, 2 tbl, 11 ex |
