Me pēhea te mahi a te motuka dc?
He mīhini te motuka DC e huri ana i te pūngao hiko hei pūngao miihini i roto i te āhua o te hurihuri. Ka puta tōna nekehanga mā te whanonga ā-tinana o te aukume hiko.Mōta DC kei roto ngā inductors, e whakaputa ana i te papa aukume e whakamahia ana hei whakaputa nekehanga. Engari me pēhea te hurihanga o tēnei papa aukume mēnā kei te whakamahia te iahiko DC?
He aukume hiko, he wahi rino kua takaihia ki te koiri waea kua tukuna he ngaohiko ki ōna pito. Mēnā ka tāpirihia kia rua ngā aukume pumau ki ngā taha e rua o tēnei aukume hiko, ka puta he taipana mai i ngā kaha pana me ngā kaha kukume. 
Kātahi, e rua ngā raruraru hei whakaoti: te whāngai i te ia ki te aukume hiko hurihuri me te kore e miro ngā waea, me te whakarerekē i te ahunga o te ia i te wā tika. Ka whakaotihia ēnei raruraru e rua mā te whakamahi i ngā taputapu e rua: he mowhiti wehewehe, me te takirua paraihe.
E kitea ana, e rua ngā wāhanga o te commutator e hono ana ki ia pito o te aukume hiko, haunga ngā pere e rua ko ngā paraihe e whakamahi ana i te iahiko ki te aukume hiko hurihuri. I roto i te ao tūturumotuka wiriMōta DC e toru ngā mokowā e kitea ana, kaua e rua, me ngā paraihe e rua.
Ma tenei, i te nekehanga o te aukume hiko, ka huri te polarity, ā, ka huri tonu te rakau. Ahakoa he māmā noa iho, ā, he pai te tangi, tera etahi take e kore ai e whai hua te hiko o enei motuka, e kore hoki e pumau te miihini, ko te raru nui ko te wā i waenga i ia hurihanga polarity. I te mea ka huri te polarity i roto i te aukume hiko i runga i te miihini, i etahi tere ka huri wawe rawa te polarity, ka hua ake he nekehanga whakamuri, ā, i etahi wa ka huri wawe rawa, ka puta he "mutu" tere i te hurihanga. Ahakoa te aha, ka puta mai i enei take he tihi iahiko me te kore pumau miihini.
I whakatūria i te tau 2007, ko Leader Microelectronics (Huizhou) Co., Ltd. he umanga ā-ao e whakauru ana i te R&D, te whakaputa me te hoko. Ko te nuinga o ā mātou mahi he whakaputamōta papatahi, motuka raina,Mōta BLDC, mōta kore-matua, mōtini SMD, mōtini whakatauira-hau, mōtini whakaheke tere me ērā atu, tae atu ki te mōtini moroiti i roto i te tono maha-marae.
