Motini paraihekore hei whakatika -

Ko te mana motopaika korekore na te kaiwhakahaere ma te motopaika korepu, te motopaika korekore ki te mahi i tetahi huarahi. Kia mataara, i roto i te ahunga o te motuka motuka me te motuka motuka ko te hurihanga karaka ka kiia ko te hurihanga whakamua, ka kiia ko te hurihanga hurihanga.
Ko nga keehi e rua e whai ake nei, me whakaaro te whakarereketanga o te motini paraihe:
(1) Mena ko te hurihanga o te miihini korepu, ka kitea me whakamua, engari ka huri te motuka tuuturu, katahi ka whakatika koe i te motuka urungi.
（2)Mehemea ko te ahua mahi o te motopaika kore he ahua me te wa ki te whakamua, ki te whakamuri, ki tetahi atu ahua me te waa me rite ki te motuka hei whakahaere i te mana mahi me te wa ki te whakatika.
i roto i te tikanga whakahaere motika dc, huri i te polarity o te ahunga papa autō, te ngaohiko armature ranei, ka taea te huri i te hurihanga motuka. Brushless dc motini rewharewha hua e aukume pūmau, ka taea te huri i te ahunga, me te tika ki te kawe kotahitanga o te semiconductor, hiko supply ngaohiko whakamuri hononga he kore tino watea. Na i roto i tenei take, te tikanga ma te whakahaere i te stator awhiowhio i roto i te tikanga ki te huri i te ahunga hurihanga nekeneke.
