He raruraru noa te mura o te rama nā te pakaru o te paraihe i roto i te whakahaere o ngā motuka DC, ngā motuka takahuri hurihuri rānei. Ehara i te mea ka tere ake te pakaru o ngā paraihe me ngā mowhiti whakawhiti/paheke i ngā mura, engari ka puta hoki he pokanoa hikohiko, ā, ka tūpono pea he tūponotanga haumaru. E tātarihia ana e Morteng ngā take o te raruraru mai i ēnei e whai ake nei:
Mahi: Tere te pakaru o te paraihe me te whakakapinga pinepine; ka kitea ngā mura i te wā e whakamahia ana, tae noa ki te wera o te mata o te mowhiti paheke; te pekepeke, te wiri rānei o te paraihe.
Ngā tino take ā-pūkaha o ngā mura ahi:
Te pā kino o te paraihe: Koinei tētahi o ngā tino take.
Kāore i te rawaka te pēhanga o te puna: Mā te koroheketanga o te puna, te rerekētanga o te āhua, te iti rawa rānei o ngā tautuhinga pēhanga tīmatanga ka kore e ranea te pēhanga pa i waenga i te paraihe me te mowhiti whakawhiti/paheke, ka piki ake te ātete pa, ka wera ake ngā pūwāhi pa, ā, ka nui ake te tūponotanga o ngā mura i te wā e whakawhiti ana te iahiko, e wiri ana rānei.
Te pēhanga puna nui rawa: Ahakoa ka pai ake te pa o te pēhanga nui, ka nui ake te waku me te pakaru o te miihini, ka nui ake te wera me te puehu waro, ā, ka kino pea te kiriata waikura i runga i te mata o te commutator, ka nui ake te mura.
Ngā paraihe e mau ana ki roto i te pupuri paraihe: Mā te āhua rerekē o te pupuri paraihe, te kohikohinga o ngā paru, te kore ōrite o ngā rahi o te paraihe, te pakaru rānei o ngā taha o ngā paraihe ka nekeneke uaua i roto i te pupuri paraihe, ka kore ai e taea te whai tika i ngā wiri iti, i te rerekētanga rānei o ngā mowhiti whakawhiti/paheke, ka hua ake he pānga kore pumau.
Ngā hapa o te mata o te commutator/mowhiti paheke: Ka taea e ngā hapa o te mata (ngā rakuraku, ngā poka, ngā tohu wera), te tino porowhita/te rerekētanga, ngā rau mika e piri ana (commutator), te nekehanga tuaka nui rānei te whakararuraru i te paheke maeneene, tonu i waenga i te paraihe me te mata hurihuri.
Te tāutanga paraihe hē: Kāore ngā paraihe i tāuta tika ki te tūranga pokapū, ki te koki tika rānei.
Te wiri nui rawa o te mīhini: Ka tukuna te wiri mai i te motuka tonu, i te taputapu taraiwa rānei ki te wāhi paraihe, ka puta te nekehanga o te paraihe.
Te pakaru kore ōrite o te commutator/mowhiti paheke: Ka hua ake he mata kore ōrite.
