He maha nga hanganga o nga motuka korepu, kaore ia he rite, ko te mutunga ko te rotor, te stator me te waahanga whakahaere motuka o te punaha miihini korepu, ko te rotor he miihini pumau me etahi atu, ko te stator he mea hangai i te awhiowhio me te rino matua, te mana motuka ma te huringa me te tirotiro i te waahanga waahanga me te hanganga o te miihini miihini korepu. Kua wehea te rotor ki roto rotor waho me rotor, rotor ki multipole aukume poraka maitai aukume annular ranei, i runga i te stator awhiowhio, tūnga kitea huānga i te wāhi motuhake i runga i te stator me te pūmana ki te mahi tahi ki tahi i te tahi, te whakahaere noa nekeneke commutation, inaianei te nuinga ki te huānga hall, ano hoki etahi atu huarahi ki te whakahaere commutation. Kaua e whakaaro ki te waahanga whakawhiti hiko, he tino ngawari te hanganga o te motuka korepu, ka taea te whakataurite ki te motuka tukutahi ac.
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.
