(1) Kout kous ant segman commutator
Sa yo rele kous kout ant segman komutateur yo vle di ke gen yon koneksyon kout sikwi ant de segman komutateur adjasan sou commutator la. Kout kous ant segman commutator. Gwo etensèl ap parèt sou sifas commutator la; lè kous kout la grav, dife bag ap fèt sou sifas commutator la.

Reparasyon kout kous la ant segman komutateur yo se jan sa a:
①Cleaning with slot cleaning sheet When the armature winding is burnt due to short-circuit fault, the fault point can be found by observation method. In order to determine whether the short-circuit fault occurs inside the winding or between the commutator segments, the winding wire head connected to the commutator segment should be disconnected, and then use a check light to check whether there is a short circuit between the commutator segments, such as on the surface of the commutator segment. If a short circuit is found, or the spark burns the scar, usually use the slot cleaning sheet shown in Figure 227 to scrape off the short-circuited metal chips, brush powder, corrosive substances, etc., until the check light is used to check that there is no short-circuit. And use mica powder and shellac or mica powder, epoxy resin and polyamide resin (650) to mix into a paste, then fill in the grooves and let it harden and dry.
②Netwaye V-Groove la ak V-bag nan blòk la commutator Si kout kous la ant chips yo pa ka elimine apre yo fin retire ak anpil atansyon debri ekstèn ant chips yo. Nan moman sa a, yo dwe demonte Komitatè a, epi yo dwe netwaye V-Gove ak V-bag nan gwoup Komitatè a ak anpil atansyon. Anvan ou demonte Komitatè a, vlope yon kouch papye elastik ki gen yon epesè 0.5 a 1 mm sou sikonferans ekstèn nan Komitatè a pou izolasyon, epi make kote fay la, ak Lè sa a, kouvri mouri a anpile, ak Lè sa a, Pran Komitatè a apa. Plis tcheke defo ki genyen ant segman komutateur yo, sifas V-Groove la ak V-bag la, epi fè fas ak yo selon defo diferan.
③ Ranplasman fèy mika ant fèy yo Si kout kous la ant fèy yo pa ka elimine pa metòd ki anwo a, se sèlman fèy mika yo ka ranplase. Metòd pou ranplase flak mika entè-chip la se jan sa a.
Put the above disassembled commutator segment on the flat plate, mark the faulty commutator segments, and then fasten it with a rubber ring, then remove the steel wire hoop or weft-free glass wire, and use a sharpened A section of the wide saw blade is inserted between the faulty pieces, after loosening, the faulty commutator piece is pulled out, and a new commutator piece of the same specification as the faulty commutator piece is inserted.
Apre yo fin ranplase plak commutator la, sèvi ak sèrkl fè (ak bwat katon epè andedan) pou tache gwoup plak commutator la. Chofe blòk commutator a 165 ℃ ± 5 ℃, sere boulon vis yo pou premye fwa, epi sèvi ak lanp kalibrasyon an pou tcheke si kout kous la ant blòk yo te elimine apre refwadisman. Si li pa elimine, ou ta dwe ak anpil atansyon jwenn kòz la nan echèk la oswa repete travay ki anwo a; si kous kout ant chips yo te elimine, fè asanble.
