METHOD TO PRODUCE MOTOR COILS Russian patent published in 2010 - IPC H02K15/12 H02K15/10 H02K3/30 H02K3/32 

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 "ЛЭС" and tape "ГИП-ТС-Пл", and six layers of glass-mica tape "ЛСЭП-934-ТПл". Then, coils are impregnated with thermosetting lacquer in vacuum-pressurisation procedure. Coils fitted in stator, the coils are additionally coated by isolation enamel "ГФ92ХС" or insulating lacquer "БТ-99".

EFFECT: higher reliability, longer life.
