Ko te putanga o toru-wahanga nekeneke tukutahikia whiriwhiria kia rite ki te mana e hiahiatia ana e te miihini whakangao, me te toru-waahanga nekeneke tukutahi kia whakahaeretia i raro i te utaina whakataua ka taea. I te wa e whiriwhiri ana i te rahinga mana o te motuka, me tika te kaupapa.
Mo te tikanga whiriwhiri o te rahinga mana otoru-waahanga tukutahitanga ACmotor.
Ko te kowhiri i tetahi motini tukutahi-toru me te mana tika e kore e whakangaro i te hiko hiko, e kore e taumaha te motini mo te wa roa. Mena he iti rawa te mana o te motuka. Ka puta te ahua o te "hariata iti", ka nui te utaina o te motuka mo te wa roa, ka pakaru nga mea whakamatao i te wera. Ahakoa ka wera te motuka, mena he nui rawa te mana o te motuka, ka puta te ahuatanga "marathon nui". Ka taea te tino whakamahi i tana mana whakaputa miihini, kaore i te teitei te mana me te kaha, me te whakaputa i te hiko hiko.
Tikanga 1: Whakamahia te tauira hei tatau i te hiko e hiahiatia ana e te motini tukutahi-toru:
- Mo te tikanga mahi tonu, ka mohiotia te mana kawenga (ara, te mana i runga i te rakau miihini) Pl (kW). Ka taea te whakamahi i te tauira e whai ake nei hei tatau i te mana P (kW) o te motini: P=P1/n1 n2 Ko n1 te mana o te miihini whakangao me te n2 te mana o te motini. Koinei te mana tuku.
E ai ki te kaha i whiwhihia e te tauira o runga ake nei, na te mea kaore e tika kia tino tika te mana me etahi atu, a ko te ngaronga o te hiko miihini he etahi taurangi, ko te mana whakatau o te motuka kua tohua kia rite ki te iti ake ranei i te mana tatau.
Mena hepūkaha hiko me te kaha o te 0.8 kua tohua, ngana ki te kimi e hia nga kilowatts me noho te mana motini. Rongoā: P=P1/n1n2=3.95/0.7*0.8=7.1kW I te mea karekau he korero mo te 7.1kW, ka tohua he motini tukutahi-toru 7.5kW.
- Te mahi mo te wa poto mo te motuka. Ka whakatauritea ki te motuka me te mana whakataurite i te wa e mahi tonu ana. Nga waahanga iti, te taipana teitei nui, me te utu iti. Ki te whakaae nga tikanga, me kowhiria he motini tukutahi-toru me te whakatauranga S2 mo te wa poto ka taea.
- Mo nga motika tukutahi-toru me te whakatauranga mahi mokowhiti o S3, tohua te rahi putanga. E ai ki te rahi o te tere tere o te utaina, ka tohua he motika koretake e toru-waahanga me te punaha whakahaere S3, he mea tino whakamahia mo te mahi mokowhiti. Ko te tātai tātai mō te uta Fs% te haere tonu ko Fs%=tg/(Tg+ki)×100%, ko Tg te wā mahi (wae: min), ko t te taipana whakatārewatanga (wae: min); Ko Tg tekau ki te wa huringa (wae: min)
Tikanga 2: Whakamahia te tikanga whaihanga ki te whiriwhiri i te mana o te motini tukutahi-toru. Ko te mea e kiia ana he whakataurite, he rite ki te mahi o te motika asynchronous e toru-waahanga e whakamahia ana i roto i nga miihini hanga rite.
Ko te tikanga motuhake ko: kia mohio ki te mana e pau ana e nga miihini hanga rite tata ki tenei waahanga, etahi atu wae ranei, katahi ka kowhiri i nga motuka tata mo te mahi whakamatautau. Ko te mahi whakamatautau he tirotiro mena he hototahi te motuka kua tohua ki te miihini whakaputa. Ko te tikanga manatoko ko: kia peia e te hiko hiko te miihini whakaputa ki te mahi. Whakamahia he inemita rawhi hei ine i te ia mahi o te motini tukutahi-toru, ka whakatairitehia te hua ine ki te naianei kua tohua ki runga i te papa ingoa motuka.
Tikanga 3: He pai te tikanga arotake:
- Mēnā karekau te nāianei mahi o te motini e tino rerekee mai i te nāianei whakaingoa kua whakaatuhia. E tohu ana tenei he rawaka te mahinga o te motuka kua tohua.
- Mena kei te 70% te iti ake o te waa mahi o te motuka i te waa kua tohua i runga i te papa ingoa. Katahi ka tohu he nui rawa te mana o te motini (arā, ko te "hariata nui" me whakakapi ki te motini iti ake te mana).
- Mena he nui ake i te 40% teitei ake i te 40% teitei atu i te rere mana kua tohua i runga i te papa ingoa. Ka tohu tenei he iti rawa te hiko o te motuka (arā, "kareti iti"), ara, me whakakapi he motuka hiko nui ake.
