Ko te ara iahiko taraiwa au pumau o te Chopper he momo aratau taraiwa he pai ake te mahi me te nui ake o te whakamahinga i tēnei wā. Ko te whakaaro matua ko te pupuri i te reiti iahiko o te takai ā-wāhanga arataki ahakoa temōta hikoikei roto i te āhua raka, kei te rere rānei i te auau iti, teitei rānei. Kei raro nei te hoahoa kauwhata o te ara iahiko taraiwa au pumau o te chopper, e whakaaturia ana tētahi ara iahiko taraiwa ā-wāhanga kotahi, ā, he rite tonu tētahi atu ā-wāhanga. Ko te whakakā-whakaweto o te takai ā-wāhanga e whakahaerehia ngātahitia ana e te ngongo whakawhiti VT1 me te VT2. Ka honoa te kaituku o VT2 ki te ātete tauira R, ā, ko te hekenga pēhanga i runga i te ātete he rite ki te iahiko I o te takai ā-wāhanga.
Ina teitei te ngaohiko o te UI whakahaere, ka whakakāhia ngā ngongo pana VT1 me VT2, ā, ka tukuna e te pūtake hiko dc te takai. Nā te awe o te inductance o te takai, ka piki haere te ngaohiko i runga i te ātete tauira R. Ina hipa te uara o te ngaohiko Ua kua hoatu, ka puta te kaiwhakatairite i te taumata iti, kia puta ai hoki te taumata iti i te kuaha. Ka tapahia te VT1, ā, ka tapahia te pūtake hiko dc. Ina iti iho te ngaohiko i runga i te ātete tauira R i te ngaohiko Ua kua hoatu, ka puta te kaiwhakatairite i te taumata teitei, ā, ka puta hoki te kuaha i te taumata teitei, ka whakakāhia anō te VT1, ā, ka tīmata anō te pūtake hiko dc ki te tuku hiko ki te takai. I ngā wā katoa, ka whakapūmauhia te iahiko i roto i te takai ā-wāhanga i te uara i whakatauhia e te ngaohiko Ua kua hoatu.
Ina whakamahia he puku hiko pūmau, ka ōrite te pūhiko hiko ki te pūhiko whakatauranga o te motuka, ā, ka noho pūmau tonu. He māmā ake, he iti ake te utu o ngā puku hiko pūmau i ngā puku hiko pūmau, e whakahaere ana i te pūhiko hiko kia tino whakaratohia he hiko pūmau pumau ki te motuka. Mō te puku hiko pūmau, ka whakawhāitihia e te ātete o te ara iahiko puku te iahiko mōrahi, ā, ka whakawhāitihia e te ine hiko o te motuka te tere o te pikinga o te iahiko. I ngā tere iti, ko te ātete te mea whakawhāiti mō te whakaputanga o te iahiko (me te taipana). He pai te mana whakahaere taipana me te tūnga o te motuka, ā, he pai te oma. Heoi, i te pikinga o te tere o te motuka, ka tīmata te ine hiko me te wā pikinga o te iahiko ki te aukati i te iahiko kia eke ki tōna uara whainga. Heoi anō, i te pikinga o te tere o te motuka, ka piki ake hoki te EMF whakamuri, ko te tikanga he nui ake te hiko hiko e whakamahia ana hei wikitoria i te hiko EMF whakamuri. Nō reira, ko te ngoikoretanga matua o te puku hiko pūmau ko te hekenga tere o te taipana i puta i te tere iti o te motuka stepper.
Kei te Whakaahua 2 te ara iahiko taraiwa o te motuka hiko takirua. E waru ngā transistors e whakamahia ana hei taraiwa i ngā huinga wāhanga e rua. Ka taea e te ara iahiko taraiwa takirua te taraiwa i ngā motuka hiko takirua-waea, e ono-waea rānei i te wā kotahi. Ahakoa ka taea e te motuka hiko takirua-waea anake te whakamahi i te ara iahiko taraiwa takirua-waea, ka taea e ia te whakaiti i te utu o ngā tono whakaputa papatipu. Ko te maha o ngā transistors i roto i te ara iahiko taraiwa motuka hiko takirua he rua ngā wā i tērā o te ara iahiko taraiwa kotahi-polar. Ko ngā transistors o raro e whā ka taraiwa tikahia e te microcontroller, ā, ko te transistor o runga e hiahia ana ki tētahi ara iahiko taraiwa o runga he utu nui ake. Ko te transistor o te ara iahiko taraiwa takirua me kawe noa i te ngaohiko motuka, nō reira kāore e hiahiatia he ara iahiko rawhi pērā i te ara iahiko taraiwa kotahi-polar.
Ko te ara iahiko taraiwa kotahi-polar me te ara iahiko bipolar ngā ara iahiko taraiwa e whakamahia whānuitia ana mō ngā motuka hikoi. E whā ngā transistors e whakamahia ana e te ara iahiko taraiwa kotahi-polar hei taraiwa i ngā huinga wāhanga e rua o te motuka hikoi, ā, kei roto i te hanganga takai stator motuka e rua ngā huinga koiri me ngā tap waenga (te tap waenga o te koiri AC O, koiri BD). Ko te tap waenga he m), ā, e ono ngā aho katoa o te motuka katoa me te hononga o waho. Kāore e taea e te taha AC te whakakaha (te mutunga BD), ki te kore ka whakakorehia e te rerenga aukume i hangaia e ngā koiri e rua i runga i te pou aukume tetahi ki tetahi, ko te kai parahi anake o te koiri ka puta. Nā te mea he rua noa ngā wāhanga (he wāhanga kotahi ngā takai AC, he wāhanga kotahi te takai BD), ko te kōrero tika me waea ono-wāhanga-rua (ko te tikanga, e rima ngā aho inaianei, kua honoa ki ngā aho tūmatanui e rua). Motoka hikoi.
Kotahi-wāhanga, ko te takai hiko-whakakā kotahi anake te wāhanga, ka whakawhitihia te iahiko wāhanga i ia wā, ka whakaputa i te koki takahanga hurihuri (ngā mīhini hiko rerekē, 18 nekehanga 15 7.5 5, ngā motuka whakauru 1.8 nekehanga me te 0.9 nekehanga, ko ngā 1.8 nekehanga e whai ake nei ka tohua ki tēnei tikanga whakaoho, ā, ko te urupare o te koki hurihanga ina tae mai ia pā. Mena he teitei rawa te auau, he ngawari ki te whakaputa i te mea kua tawhito.
Whakaoho rua-wāhanga: te rere o te iahiko e rua-wāhanga i te wā kotahi, ka whakamahia hoki te tikanga whakawhiti i ngā iahiko wāhanga, ko te koki hiko o te kaha tuarua-wāhanga he 1.8 nekehanga, ko te iahiko katoa o ngā wāhanga e rua he 2 ngā wā, ā, ka piki ake te auau tīmatanga teitei rawa, ka taea te whiwhi tere teitei, tāpiri, mahi nui rawa.
1-2 Whakaohooho: He tikanga tēnei mō te mahi tauwhitiwhiti i te whakaoho ā-wāhanga, te whakaoho ā-wāhanga-rua, te au tīmatanga, ka huri tonu ia rua, nō reira ko te koki taahiraa he 0.9 nekehanga, he nui te au whakaohooho, ā, he pai te mahi nui rawa atu. He teitei hoki te auau tīmatanga mōrahi. E mōhiotia whānuitia ana ko te puku whakaoho ā-haurua.
