C, armature coil C to be placed in stator core bottom land right hand corner, to pat armature coil gently by instruments such as mallet, groove lining bars, they are closely arranged in groove; The exhaust position of armature coil C is closely close to the position of armature coil B as far as possible, and now the half bottom land of this groove fills up;
D, armature coil A is placed on below armature coil B, pats armature coil gently by instruments such as mallet, groove lining bars, they are closely arranged in groove;
E, armature coil D is placed on below armature coil C, pats armature coil gently by instruments such as mallet, groove lining bars, they are closely arranged in groove;
F, adjustment is a little being carried out to the space left in the middle of in groove, making wiring both sides in groove symmetrical;
G, the insulating paper embedded groove internal pore place that use 0.5mm is thick, by armature coil embedded groove, and extract the thick insulating paper of 0.5mm out gently; Adjust the arrangement of the conductor of this groove, make their arrangements neat, attractive in appearance.
Described armature coil A, armature coil B, armature coil C, armature coil D all adopt every 50 polyester-imide line insulating papers to wrap up into a branch of.
Groove lining bar, in put procedure, is all placed in the groove placed, knocks gently with mallet by described armature coil A, armature coil B, armature coil C, armature coil D, reaches closely stack coil effect with this.
The present invention installs simple and convenient, solves the narrower problem being not easy to rule of notch, coil can be allowed to arrange in groove closely and more firmly, make motor have superperformance, apply and have good economic and social benefit.
