He taputapu hiko te commutator e whakamahia ana i roto i teMōta DCKo tāna mahi he whakarerekē i te ahunga o te iahiko i roto i te motuka, kia rerekē ai te ahunga o te hurihanga o te motuka. I roto i te motuka DC, me whakarerekē te ahunga o te iahiko i ia wā kia mau tonu ai te ahunga hurihanga o te motuka. Ko te mahi a te commutator he whakarerekē i te ahunga o te iahiko i ia wā ina huri te motuka, kia taea ai e te motuka te huri tonu me te pumau.
Ko te kaupapa matua o te whakawhitiwhiti hiko ko te whakamahi i tētahi huinga pana miihini me ngā hononga hiko hei whakarerekē i te ahunga o te rere o te iahiko. Ina huri te motuka, ka whakahaerehia e te whakawhitiwhiti hiko te whakakā me te whakaweto o te iahiko e ai ki te tūranga me te ahunga o te hurihanga o te rotor, ā, ka whakarerekē i te ahunga o te iahiko. Ko tēnei momo whakawhitiwhiti hiko e whakamahia ana i roto i ngā motuka DC iti ake te mana, pērā i ngā taputapu whare, ngā taputapu miihini iti, me ētahi atu.
I roto i te motuka DC tuku iho, he maha ngā wāhanga o te commutator: te anga, ngā pou, te commutator me ngā paraihe. Ko te anga te wāhanga hurihuri o te motuka, ā, ko ngā pou aukume te wāhanga stator o te motuka. Ko te commutator he huinga pana miihini me ngā hononga hiko e whakarerekētia ai te ahunga o te iahiko. Ko te paraihe te wāhanga e hono ana i te pūtake hiko me te motuka, ā, e whakauru ana i te iahiko ki roto i te koiri o te motuka mā te paraihe.
Haunga ngā whakawhitiwhiti miihini, he whānuitia hoki te whakamahi a ngā motuka DC hou i te hangarau whakawhitiwhiti hiko. Ka whakamahia e te hangarau whakawhitiwhiti hiko he kaiwhakahaere hiko hei whakarerekē i te ahunga o te iahiko, kia puta ai te whakawhitiwhiti o te motuka. Ki te whakatauritea ki ngā whakawhitiwhiti miihini, he nui ake te tika me te pono o te hangarau whakawhitiwhiti hiko, ā, ka taea te whakatutuki i te whakahaere whakawhitiwhiti tika ake. Nō reira, kua whānuitia te whakamahi i roto i ētahi tono e hiahia ana kia teitei te tika o te whakawhitiwhiti.
He mea nui te mahi a te commutator i roto i ngā motuka DC, e pā ana ki te mahi, te whai huatanga me te pono o te motuka. Ka taea e te commutator pai te whakarite kia pumau, kia whai hua hoki te mahi a te motuka, ā, ka roa ake te ora o te motuka. Nō reira, he mea tino nui te hoahoa, te hanga me te tiaki i te commutator.
I te whanaketanga tonu o te hangarau, kei te whakapai tonu te hangarau hoahoa me te hanga o ngā commutators, ā, kei te puta tonu mai ngā hangarau commutation hiko hou, e ngāwari ake ai, e pono ake ai hoki te whakamahinga o ngā commutators i roto i ngā motuka DC. I te whanaketanga tonu o te hangarau motuka, ka whakapai tonuhia, ka arotauhia hoki ngā commutators kia tutuki ai ngā hiahia tono e huri haere ana.
I roto i te poto, hei wāhanga nui o te motuka DC, ka whakamahia te commutator hei whakarerekē i te ahunga o te ia o te motuka, kia rerekē ai te ahunga o te hurihanga o te motuka. Mā te hangarau whakawhitiwhiti miihini, hiko rānei, ka taea e te commutator te whakarite kia pumau te mahi a te motuka, ā, e whakamahia whānuitia ana i roto i ngā taputapu whare, ngā taputapu ahumahi, ngā motuka me ētahi atu mara. I te whanaketanga tonu o te hangarau, kei te whakapai tonuhia te hoahoa me te hanga o te commutator kia tutuki ai ngā whakaritenga tono e huri haere ana.
