(I) Brevis circuitus inter segmenta commutatoris
Sic dictus brevis circuitio inter segmenta commutatoris significat quod est brevis circuitus nexus inter duo segmenta commutatoris adjacentia in commutatore. Brevis circuitus inter segmenta commutatoris. Magnae scintillae in superficie commutatoris apparebit; si brevis circuitus gravis est, anulus ignis in superficie commutatoris occurret.

Reparatio circuli brevis inter segmenta commutatoris haec est:
① Purgatio cum socors purgatio sheet Cum armatura flexuosa comburitur propter breve spatium culpa, punctum culpae observatione methodi inveniri potest. Ad diiudicandum an culpa brevis circuitus intra ambages an inter segmenta commutatoris occurrat, caput filum flexuosum cum segmento commutatoris cohaerens divelli debet, ac deinde perscriptio levis inspicienda sitne brevis circuitus inter commutatorem. segmenta, ut in superficie segmenti commutatoris. Si brevis circuitio inveniatur, vel scintilla urit cicatricem, uti solet slot purgatio scheda in Figura 227 ostensa ad radendum breves astulas metallicas, penicillo pulvere, corrosivis substantiis, donec ad reprimendum lumen adhibitum est etc. nullum breve spatium reprehendo. Et utere pulvere micas et shellac vel micas pulveris, epoxy resinam et resinam polyamidem (650) in farinam commisce, deinde sulci imple et indurescant et siccantur.
②Clean the V-groove and V-ring of the commutator block If the short circuit between the chips cannot be eliminated after carefully removing the external debris between the chips. At this time, the commutator must be disassembled, and the V-groove and V-ring of the commutator group must be carefully cleaned. Before disassembling the commutator, wrap a layer of elastic paper with a thickness of 0.5 to 1 mm on the outer circumference of the commutator for insulation, and mark the fault location, and then cover the stacking die, and then Take the commutator apart. Further check the faults between the commutator segments, the surface of the V-groove and the V-ring, and deal with them according to different faults.
③ Substitutio schedae speculatoriae inter schedas Si brevis ambitus inter chartas modo praedicto tolli non potest, solum schedae adsimulatae restitui possunt. Modus reposuit incanduit incandescentiae speculares talis est.
Pone superius disgregata segmentum commutatoris in plana lamina, segmenta commutatoris vitiosa nota, et deinde anulo anulo globulo cinge, deinde circulum filum ferreum vel subtemen vitreum sine filo vitreo, et utere acuto Sectio latae serrae laminae. inter vitiosos frusta post laxitatem inseritur, vitiosus commutatoris fragmentum evellitur, et novum commutatoris eiusdem speciei cum vitio commutatoris fragmentum inseritur.
After the commutator plate is replaced, use iron hoops (with thick cardboard inside) to fasten the commutator plate group. Heat the commutator block to 165℃±5℃, tighten the screws for the first time, and use the calibration lamp to check whether the short circuit between the blocks has been eliminated after cooling. If it is not eliminated, you should carefully find the cause of the failure or repeat the above work; if the short circuit between the chips has been eliminated, perform assembly.
