METHOD TO PRODUCE MOTOR COILS

摘要

FIELD: electrical engineering. ^ SUBSTANCE: coils are wound on the frame by copper wire coated with polyethylene lacquer. Coils surface is insulated by a layer of insulating tapes. Isoflex spacers are arranged between layers of turns. Note that coil surface insulation is made by one layer of tape "¡" and tape "ôÿ--", and six layers of glass-mica tape "¡-934-". Then, coils are impregnated with thermosetting lacquer in vacuum-pressurisation procedure. Coils fitted in stator, the coils are additionally coated by isolation enamel "ôñ92Ñ" or insulating lacquer "æ-99". ^ EFFECT: higher reliability, longer life. ^ 1 dwg
