Ko te rereketanga i waenga i te kaiwhakahaere motuka dc me te kaiwhakahaere motuka ac he aha te nuinga? I raro i te hanga iti me koutou katoa ki te korero. 1. He maamaa, he uaua hoki te kaupapa o te kaiwhakahaere motuka dc, he uaua ki te pupuri, he rereke noa te mana whakahaere ac. 2. Dc pūmana nekeneke ko te whakamahi o te paraihe me te commutator, ki te whakauru i te nāianei i roto i te rotor o te armature, hanga i te rotor kaha hurihuri hua i roto i te papa autō stator; Ko te ac motika pūmana ko te rere hiko ac ki roto i te awhiowhio stator, he papa autō i roto i te manawa stator, a ka i roto i te rotor awhiowhio te nāianei, huri i te rotor i runga i te stator autō kaha mara. 3. He pai te whakahaere tere o te mahi a te kaiwhakahaere motuka dc, te whanui tere tere, te whakahaere tere i raro i te kawenga taumaha; Ko te tino pai o te kaiwhakahaere motuka ac, i te wa e whakamahi ana, kaore he haunga paowa, kaore he parahanga, he haruru iti. I runga ake i nga mea katoa, e mohio ana matou mo te rereketanga o nga mea e rua kei reira.
Ko te roopu HOPRIO he kaihanga ngaio o te kaiwhakahaere me nga motuka, i whakapumautia i te 2000. Te tari matua o te roopu i Changzhou City, Jiangsu Province.
