He aha te motuka aukume tuturu? He aha tōna rerekētanga mai i te motuka hiko noa?

—Nō reira ka ara ake te pātai mō te tikanga o te kupu 'mōta aukume tuturu'. He aha ngā āhuatanga e rerekē ai i te mōta tuku iho?

A motuka AC aukume tuturu(PMM) e tautuhia ana heimotuka hikoe whakamahi ana i ngā āhuatanga aukume ā-roto o ngā aukume tuturu hei whakaputa i te papa aukume e hiahiatia ana mō tana mahi. He rerekē ki ngā motuka tuku iho, e whakawhirinaki ana ki te aukume hiko e whakakahangia ana e te iahiko o waho hei whakaputa i te papa aukume, ka whakamahia e te PMM te aukume ā-roto o ngā aukume tuturu. Nā tēnei rerekētanga taketake o te hoahoa ka puta he maha ngā painga nui, inā koa e pā ana ki te whai huatanga me te tiaki pūngao.

Ko te painga matua o ngā motuka aukume tuturu ko tōna tino pai me te kaha ki te penapena pūngao. Ko te korenga o tētahi atu hiahia aukume hei whakaputa i tētahi papa aukume he tohu i te whakaiti nui i te ngaronga pūngao i te wā e mahi ana, he painga kei roto i ngā motuka aukume tuturu. Nā tēnei pai ake o te pai ka whakaitihia te whakamahinga pūngao, ā, ka waiho ngā motuka aukume tuturu hei kōwhiringa whakamīharo mō ngā momo tono kanorau, tae atu ki ngā waka hiko me ngā mīhini ahumahi.

He rerekē, ko ngā motuka tuku iho (pērā imotuka hiko hiko whakapūmaus) e whakawhirinaki ana ki te rere o te iahiko i roto i te koiri hei hanga i tētahi papa aukume. Ka hua ake tēnei tukanga i te ngaronga o te pūngao nā te wera me ētahi atu āhuatanga, ka whakaiti i te whai huatanga whānui. Nō reira, ka taea te whakatau ko te motuka tikanga me nui ake te whakaurunga pūngao kia tutuki ai te taumata putanga rite ki te motuka aukume tuturu.

Hei tāpiri atu, mā te hoahoa kiato o ngā motuka aukume tuturu ka taea te hanga i ngā whirihoranga motuka mama ake, kiato ake hoki, he mea tino pai tēnei i roto i ngā tono e whakaarohia nuitia ana te wāhi me te taumaha. Hei tāpiri atu, ko ngā motuka aukume tuturu e whakaatu ana i ngā āhuatanga mahi pai ake, tae atu ki te kiato taipana teitei ake me ngā wā urupare tere ake.

Ko te rerekētanga matua i waenga i te motuka aukume tuturu me te motuka noa ko te tikanga e whakaputa ai i te papa aukume. Nā te kaha penapena-pūngao o ngā motuka aukume tuturu, he mea tino pai mō ngā tono maha o nāianei, he rerekē ki ngā hoahoa motuka tuku iho.
