Maitiro ekusarudza uye kuenzanisa iyo inverter zvinoenderana neiyo mota mutoro hunhu?

Kana inverter inoenderana inosarudzwa kune inosiyana frequency mota, bvunzo mbiri dzinotevera dzekuongorora dzinofanirwa kuitwa pahwaro hwekuongororwa kwakadzama kwehunhu hwekutakura pasi pemamiriro chaiwo ekushanda emota: 1) kuenderana kwemagetsi kweiyo inverter pachayo; 2) hapana-mutoro, mutoro, kugadzirisa maitiro ekuita senge vibration uye ruzha panguva yekumhanya.

1 Kugara torque mutoro

Kana iyo frequency yekushandura yekumhanyisa regulation ikaitwa pasi peiyo inogara torque mutoro, iyo yekupokana torque pane mota inobuda shaft icharamba isina kuchinjika panguva yekuwedzera kana kudzikisa kukurumidza, asi iyo yakanyanya kukosha yekumhanya yekuwedzera haibvumidzwe kudarika iyo yakatarwa. kumhanya, kana zvisina kudaro mota ichapiswa nekuda kwekuremerwa kushanda.Mukuita kwekuwedzera kwekumhanya, hapana chete kuramba torque, asiwo inertia torque kudzivirira shanduko yekumhanya, kuitira kuti torque iri pamota shaft ipfuure yakayerwa torque yemota, uye kukanganisa kwakasiyana kwemagetsi kunogona kukonzereswa nekuda kweshaft. kuputsika kana kupisa kwemhepo.Iyo inonzi inogara torque yekumhanyisa regulation inonyatso inoreva kune inogara torque pane inobuda shaft yemota kana kumhanya kuchigadziriswa kune chero kumhanya kwekushanda kwakagadzikana, uye inokwanisa kutyaira inogara torque mutoro.Mukuita kwekukwira kwemota kana kudzikisira, kuitira kupfupisa nguva yekuchinja, mukati meiyo inotenderwa huwandu hwesimba remagetsi emota uye kukwira kwekushisa kwemota, shaft yemotor inofanirwa kukwanisa kuburitsa yakakura zvakakwana kukurumidza kana. braking torque, kuitira kuti mota igone kukurumidza kupinda mukutenderera kunogara kutenderera. torque kumhanya mamiriro.

2 Nguva dzose simba rekutakura

Iyo torque-speed maitiro esimba rinogara richireva chokwadi chekuti simba rinopihwa nemotor rinoda kugara rakagara kana michina kana muchina wachinja mukumhanya kwekushanda. Hunhu hunodiwa hweyakakwira torque uye kumhanya kwakanyanya, ndiko kuti, mota inofanirwa kutyaira yakasiyana torque uye inogara ichiremerwa simba.

Kana simba remota richiwedzera nekuwedzera kwefrequency, kana voltage yemotor yasvika kune yakatemerwa voltage yemota, haibvumirwe kuenderera mberi nekuwedzera voltage nekuwedzera kwefrequency, zvikasadaro mota insulation ichave. yakaputsika nekuda kwekuwedzeredza .Nechikonzero ichi, mushure mekunge mota yasvika kune yakayerwa voltage, kunyangwe iyo frequency inowedzera, iyo mota voltage inoramba isina kuchinjika. Simba iro mota inogona kubuda inotarwa nechigadzirwa cheiyo yakatemerwa voltage uye yakayerwa ikozvino yemota, uye yazvino haichachinji ne frequency. Yakawana nguva dzose voltage, inogara iripo uye inogara ichishanda simba.

Kunze kwesimba rinogara riripo uye rinogara richiremerwa torque, mimwe michina inoshandisa simba rinosiyana zvakanyanya nekumhanya kwekushanda.Zvemidziyo yakaita semafeni nemapombi emvura, torque yekupikisa yakaenzana neyechipiri kusvika ku3 simba rekumhanya, ndiko kuti, square torque yekudzikisa mutoro hunhu, inongoda kusarudza iyo inochengetedza simba inverter zvinoenderana nenzvimbo yakatarwa; Kana iyo mota ikashandiswa, zvinodikanwa zvekuita zvemota panguva yese yekutanga maitiro kubva pakumira kusvika kune yakajairika kumhanya kumhanya kunofanirwa kutariswa zvakanyanya.
