<P>PROBLEM TO BE SOLVED: To provide the rotor of a rotary electric machine in which an uncured resin can be made to flow smoothly between the tongue of a bobbin and the claw of a core while exhibiting significant magnetic noise prevention effect, and to provide a manufacturing method therefor. <P>SOLUTION: In the rotor 1 where a magnetic field coil 6 wound around an insulation bobbin 5 is arranged between a pair of pole cores 3, 4, and a Lundell type pole core is bonded by a shaft 2, a folding part is provided near the root of the tongue 56(57) of the insulation bobbin 5 and tilted to the outside. A swollen streak 18 (a concave groove 19 having both open ends) is formed in the tongue 56(57) when it is pressed against the inner wall surface of the claw 33(43) of the pole cores 3, 4 and deformed to the inside. When the magnetic field coil 6 is coated with an uncured resin and impregnated therewith, the uncured resin flows smoothly into the concave groove 19, and the tongue 56 and the inner wall surface of the claw 33 are bonded rigidly by making the resin thermosetting. <P>COPYRIGHT: (C)2012,JPO&INPIT |
