1. Whakataki omōta hikoi
E mōhiotia ana hoki te mōtini takahuri ko te mōtini pāorooro, te mōtini takahuri rānei. Ka neke whakamua i tētahi koki i ia wā ka whakarerekētia te āhua whakaohooho e ai ki te tohu pāorooro tāuru, ā, ka noho pūmau i tētahi tūranga ina kore e rerekē te āhua whakaohooho. Mā tēnei ka taea e te mōtini takahuri te huri i te tohu pāorooro tāuru ki tētahi nekehanga koki e rite ana mō te putanga. Mā te whakahaere i te maha o ngā pāorooro tāuru ka taea e koe te whakatau tika i te nekehanga koki o te putanga kia tutuki ai te tūnga pai rawa atu; ā, mā te whakahaere i te auau o ngā pāorooro tāuru ka taea e koe te whakahaere tika i te tere koki o te putanga me te whakatutuki i te kaupapa o te whakahaere tere. I te mutunga o te tekau tau atu i 1960, i puta mai he maha o ngā mōtini takahuri mahi, ā, kua tere te whanaketanga o ngā tau 40 kua pahure ake nei. Kua taea e ngā mōtini takahuri te hono atu ki ngā mōtini DC, ngā mōtini kore-tukutahi, me ngā mōtini tukutahi, ā, ka noho hei momo mōtini taketake. E toru ngā momo mōtini takahuri: te tauhohe (momo VR), te aukume tuturu (momo PM) me te ranu (momo HB). Ka whakakotahi te mōtini takahuri ranu i ngā painga o ngā momo tuatahi e rua o te mōtini takahuri. Ko te mōtini takahuri he rotor (matua takahuri, aukume tuturu, pou, peera pōro), he stator (takai, matua stator), taupoki pito o mua me muri, me ētahi atu. Ko te mōtini takahuri ranu-rua-wāhanga tino noa he stator me ngā niho nui e 8, ngā niho iti e 40 me te rotor me ngā niho iti e 50; ko te mōtini toru-wāhanga he stator me ngā niho nui e 9, ngā niho iti e 45 me te rotor me ngā niho iti e 50.
