Abstract

PURPOSE: To prevent the insulator of a lead branching part of the coil from cracking and improve a humidity-absorbing insulation resistance property, by inserting a lead filler impregnated with flexible resin into the lead branching part to make this part flexible.
CONSTITUTION: The lead filler 5 made by impregnating the flexible resin in the insulator is inserted into the lead branching part 4 for a conductor 1 and a lead wire 3. Insulator tapes 2, 6 are wound on the conductor 1 and the lead wire 3. The entire coil is impregnated with thermosetting resin. Thereby, the lead branching part 4 is made flexible. Thus, damages such as cracks do not take place in the part 4 even if electromagnetic or mechanical stress occurs in operation. The hymidity-absorbing insulation resistance property of the coil is prevented from falling.
