Motini paraihekore hei whakatika -

Ko te mana motopaika korekore na te kaiwhakahaere ma te motopaika korekore, te motuka korepara kia mahi i te huarahi kotahi. 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 whakamuri.
Ko nga keehi e rua e whai ake nei, ko te whakarereketanga o te motini paraihe kore e tika kia whakaarohia:
(1) Mena ko te hurihanga o te motuka korepu, ka kitea me whakamua, engari ka huri te motuka tuuturu, katahi ka whakatika koe i te motuka urungi.
（2)Mena kei roto i tetahi ahuatanga me te wa ki te anga whakamua te ahua mahi o te motopaika korepu, ki te whakamuri, ki tetahi atu ahua me te waa me rite ki te motuka hei whakahaere i te mana mahi me te waa 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 motor flux hua e aukume pūmau, ka taea te huri i te ahunga, a na te kawe kotahitanga o te semiconductor, kaore i te tino watea te hononga whakamuri ngaohiko hiko. 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.
