Ko te rereketanga i waenga i te kaiwhakahaere motuka dc me te kaiwhakahaere motuka ac

1. Ko te kowhiringa o te hiko hiko, ka whiriwhirihia te mana hiko dc he mana hiko dc, ka whiriwhiri i te mana hiko ac ac. 2. O te hanganga rereke: dc motini kaiwhakahaere me te commutator, me te ac motini kaiwhakahaere kahore commutator. Dc nekeneke pūmana i roto i te iti ngaohiko whakaritenga o te ara iahiko, dc mana supply, watea ki te kawe. 3. Te aroaro o te commutator: te tikanga korero, i reira he pūmana mō te dc nekeneke commutator, vice mo ac nekeneke pūmana. Ka taea e te kaiwhakahaere motuka Dc te whakamahi i te commutator ki te huri i te ahunga o te naianei i roto i te coil, kia rite ki te whakatutuki i te ahotea pōkai i roto i te ahunga kotahi me te pānga o te hurihanga tonu.
