Kugadziriswa kweinjini kwakakosha pakuwedzera hupenyu hwemutakuri wako.Muchokwadi, kusarudzwa kwekutanga kweinjini yakakodzera kunogona kuita mutsauko mukuru muchirongwa chekuchengetedza.
Nekunzwisisa zvinodikanwa zve torque zvemota uye nekusarudza iwo chaiwo makina hunhu, munhu anogona kusarudza mota inogara makore mazhinji kupfuura waranti ine kushoma kugadzirisa.
Basa guru remotokari yemagetsi nderekugadzira torque, zvinoenderana nesimba uye kumhanya.Sangano reNational Electrical Manufacturers Association (NEMA) rakagadzira dhizaini yekuisa zviyero zvinotsanangura kugona kwakasiyana kwemotor.Aya maclass anozivikanwa seNEMA dhizaini macurves uye anowanzo yemhando ina: A, B, C, uye D.
Imwe neimwe curve inotsanangura yakajairwa torque inodiwa kutanga, kukurumidza uye kushanda nemitoro yakasiyana.NEMA Dhizaini B mota dzinonzi dzakajairwa mota.Iwo anoshandiswa mumhando dzakasiyana dzekushandisa apo yekutanga ikozvino yakadzikira zvishoma, uko yakakwirira yekutanga torque haidiwe, uye uko mota isingade kutsigira mitoro inorema.
Kunyangwe NEMA Dhizaini B inovhara ingangoita makumi manomwe muzana emamota ese, mamwe torque madhizaini anodiwa dzimwe nguva.
NEMA A dhizaini yakafanana nedhizaini B asi ine yepamusoro yekutanga ikozvino uye torque.Dhizaini A motors akanyatsokodzera kushandiswa neVariable Frequency Drives (VFDs) nekuda kweiyo yakakwira yekutanga torque inoitika kana mota ichimhanya padhuze nekuzara kwakazara, uye iyo yepamusoro yekutanga ikozvino pakutanga haina kukanganisa kuita.
NEMA Dhizaini C uye D mota dzinonzi dzakakwirira kutanga torque mota.Iwo anoshandiswa kana torque yakawanda ichidikanwa kutanga mukuita kuti utange mitoro inorema kwazvo.
Musiyano mukuru pakati peNEMA C uye D dhizaini huwandu hwemota yekupedzisira yekumhanya inotsvedza.Kutsvedza kwemota kunobata zvakananga kumhanya kwemota pakuzara kwakazara.Iyo ina-pole, isina-inotsvedza mota inomhanya pa1800 rpm.Iyo mota imwechete ine yakawanda inotsvedza inomhanya pa1725 rpm, nepo mota ine zvishoma inotsvedza ichimhanya pa1780 rpm.
Vazhinji vagadziri vanopa akasiyana akajairwa mota dzakagadzirirwa akasiyana NEMA dhizaini macurves.
Huwandu hwe torque inowanikwa nekumhanya kwakasiyana panguva yekutanga hwakakosha nekuda kwezvinodiwa zvekushandisa.
Conveyors inogara torque application, zvinoreva kuti torque yavo inodiwa inoramba iripo kana yangotanga.Nekudaro, maconveyor anoda yekuwedzera torque yekutanga kuve nechokwadi chekugara torque kushanda.Mimwe michina, yakadai sedhiraivha frequency drives uye hydraulic clutches, inogona kushandisa breaking torque kana bhandi rekutakura richida torque yakawanda kupfuura injini inogona kupa isati yatanga.
Chimwe chezviitiko zvinogona kukanganisa kutanga kwemutoro ndeye low voltage.Kana iyo yekuisa yemagetsi voltage inodonha, iyo inogadzirwa torque inodonha zvakanyanya.
Paunenge uchifunga kana iyo mota torque yakakwana kutanga mutoro, iyo yekutanga voltage inofanirwa kutariswa.Hukama pakati pevoltage uye torque ibasa requadratic.Semuenzaniso, kana magetsi akadonha kusvika pa85% panguva yekutanga-up, mota inoburitsa inenge 72% ye torque pazere voltage.Zvakakosha kuongorora torque yekutanga yemotokari maererano nemutoro pasi pemamiriro ezvinhu akaipisisa.
Zvichakadaro, iyo yekushanda chinhu huwandu hwekuremerwa iyo injini inogona kumira mukati metembiricha renji pasina kupisa.Zvinogona kuita sekuti iyo yakakwirira yemitengo yebasa, zviri nani, asi izvi hazvisi nguva dzose.
Kutenga injini yakakura kwazvo kana isingaite nesimba guru kunogona kukonzera kutambisa mari nenzvimbo.Nenzira yakanaka, injini inofanira kushanda nguva dzose pakati pe80% ne85% yesimba rakarongwa kuti riwedzere kushanda.
Semuyenzaniso, mota dzinowanzoita kugona kwakanyanya pamutoro wakazara pakati pe75% ne100%.Kuti uwedzere kushanda zvakanaka, chishandiso chinofanira kushandisa pakati pe80% ne85% yesimba reinjini rakanyorwa pane nameplate.
