Pamene inverter yofananira imasankhidwa kuti ikhale yosinthika pafupipafupi mota, mayeso awiri otsimikizira otsatirawa ayenera kuchitidwa pamaziko a kusanthula mwatsatanetsatane za katunduyo pansi pa zochitika zenizeni za galimotoyo: 1) kuyanjana kwamagetsi kwa inverter yokha; 2) palibe katundu, katundu, kusintha magwiridwe antchito monga kugwedezeka ndi phokoso pa liwiro.
1 Katundu wokhazikika wa torque
Pamene kayendetsedwe ka liwiro la kutembenuka kwafupipafupi kumachitidwa pansi pa katundu wokhazikika wa torque, torque yotsutsa pa shaft yotulutsa galimoto imakhala yosasinthika panthawi yowonjezereka kapena kuchepetsa liwiro, koma kukwera kwapamwamba kwa liwiro lowonjezereka sikuloledwa kupitirira chiwerengerocho. liwiro, apo ayi galimoto adzatenthedwa chifukwa ntchito mochulukirachulukira.Pakuwonjezereka kwa liwiro, sikumangokhalira kukana torque, komanso torque ya inertia kuteteza kusintha kwa liwiro, kotero kuti torque yomwe ili pa shaft yamoto imaposa torque yovotera yamotoyo, ndipo zolakwika zosiyanasiyana zamagetsi zitha kuyambitsidwa chifukwa cha shaft. kusweka kapena kutenthedwa kwa ma windings.Zomwe zimatchedwa kuthamanga kwa torque pafupipafupi zimatanthawuza ma torque okhazikika pamakina otulutsa agalimoto pomwe liwiro limasinthidwa ku liwiro lililonse kuti ligwire ntchito yokhazikika, ndipo imatha kuyendetsa katundu wokhazikika.M'kati mwa mathamangitsidwe agalimoto kapena kutsika, kuti mufupikitse nthawi yosinthira, mkati mwazovomerezeka zamphamvu zamakina agalimoto ndi kukwera kwa kutentha kwa mota, shaft yamoto iyenera kutulutsa kuthamangitsa kwakukulu kokwanira kapena braking torque, kotero kuti galimotoyo imatha kulowa mwachangu liwiro lozungulira. torque kuthamanga state.
2 Kuchuluka kwamphamvu kwanthawi zonse
Kuthamanga kwamphamvu kwamphamvu kwanthawi zonse kumatanthawuza kuti mphamvu yoperekedwa ndi mota iyenera kukhala yosasinthika pomwe zida kapena makina akusintha kuthamanga kwa ntchito. Zofunikira zamakokedwe okwera komanso kuthamanga kwambiri, ndiye kuti, injiniyo iyenera kukhala ndi mphamvu yoyendetsa ma torque osiyanasiyana komanso kunyamula mphamvu nthawi zonse.
Pamene voteji ya galimoto ikuwonjezeka ndi kuwonjezeka kwafupipafupi, ngati voteji ya galimoto yafika pamagetsi ovotera a galimotoyo, sikuloledwa kupitiriza kuonjezera voteji ndi kuwonjezeka kwafupipafupi, mwinamwake kusungunula kwa galimoto kudzakhala. zawonongeka chifukwa cha kuchuluka kwamagetsi.Pachifukwa ichi, injini ikafika pamagetsi ovotera, ngakhale kuchuluka kwafupipafupi kumawonjezeka, mphamvu yamagetsi imakhalabe yosasinthika. Mphamvu yomwe injiniyo imatha kutulutsa imatsimikiziridwa ndi zomwe zidavotera komanso zomwe zidavotera pamotoka, ndipo magetsi sasinthanso ndi ma frequency. Iwo akwaniritsa voteji mosalekeza, nthawi zonse panopa ndi ntchito mphamvu mosalekeza.
Kupatula mphamvu zokhazikika komanso zonyamula ma torque nthawi zonse, zida zina zimagwiritsa ntchito mphamvu zomwe zimasiyana kwambiri ndi liwiro logwira ntchito.Pazida monga mafani ndi mapampu amadzi, torque yotsutsa ndiyofanana ndi 2 mpaka 3 mphamvu ya liwiro lothamanga, ndiye kuti, mawonekedwe ochepetsera ma torque a square, amangofunika kusankha inverter yopulumutsa mphamvu malinga ndi malo ovotera; Ngati injiniyo ikugwiritsidwa ntchito, zofunikira zagalimoto panthawi yonse yoyambira kuyambira pakuyima kupita ku liwiro lanthawi zonse ziyenera kuganiziridwa mozama kwambiri.
