Eyona nto ichanekileyo ye-asynchronous motors kukuba kukho umahluko phakathi kwesantya sangempela semoto kunye nesantya samagnetic field, oko kukuthi, kukho ukutyibilika; xa kuthelekiswa nezinye iiparamitha zokusebenza zemoto, ukutyibilika kwemoto yeyona nto ilula ukuyifumana, kwaye nawuphi na umsebenzisi wemoto unokusebenzisa into elula.
Kwimbonakalo yeeparamitha zentsebenzo yemoto, isantya sokutyibilika yiparamitha yokusebenza ebaluleke kakhulu, ebonakaliswa ngepesenti yesiliphu esinxulumene nesantya esihambelanayo. ye.Ngokomzekelo, i-motor frequency 2-pole motor enesantya sokutyibilika se-1.8% kunye ne-12-pole motor inomahluko omkhulu kwisiliphu sokwenyani. Xa izinga lokutyibilika lifana ne-1.8%, ukutyibilika kwe-2-pole power frequency frequency motor asynchronous yi-3000 × 1.8% = 54 rpm, ukutyibilika kwe-12-pole power frequency motor yi-500 × 1.8% = 9 rpm.Ngokufanayo, kwiimotor ezineepali ezahlukeneyo ezine-slip efanayo, i-slip ratios ehambelanayo nayo iya kwahluka kakhulu.
Ukusuka kucazululo lokuthelekisa iikhonsepthi zokutyibilika kunye nokutyibilika, ukutyibilika lixabiso elipheleleyo, oko kukuthi, umahluko opheleleyo phakathi kwesantya sokwenyani kunye nesantya semagnethi esihambelanayo, kwaye iyunithi yi-rev/min; ngelixa ukutyibilika kungumahluko phakathi kwesiliphu kunye nesantya esihambelanayo . ipesenti.
Ke ngoko, isantya esihambelanayo kunye nesantya sokwenyani semoto kufuneka saziwe xa kubalwa isiliphu.Ukubalwa kwesantya esihambelanayo semoto sisekwe kwifomula n = 60f/p (apho i-f yi-frequency elinganisiweyo yemoto, kwaye i-p linani leepali zepali zemoto); ngoko ke, isantya synchronous ehambelana frequency amandla 2, 4, 6, 8, 10 kunye 12 Izantya 3000, 1500, 1000, 750, 600 kunye 500 rpm.
Isantya sangempela semoto sinokubonwa ngokwenene yi-tachometer, kwaye iphinda ibalwe ngokwenani leenguqu ngomzuzu.Isantya sangempela se-asynchronous motor singaphantsi kwesantya esihambelanayo, kwaye umahluko phakathi kwesantya esihambelanayo kunye nesantya sangempela sisiliphu se-asynchronous motor, kwaye iyunithi i-rev / min.
Zininzi iindidi zeetachometers, kunye ne-electronic tachometers yingcamango eqhelekileyo: izixhobo zokulinganisa isantya esijikelezayo ziyilwe zaze zenziwa ngokusekwe kubuchwephesha be-elektroniki bale mihla ngokubanzi zinezivamvo kunye neziboniso, kwaye ezinye zikwanazo nophawu oluphumayo kunye nolawulo.Ihluke kwi-teknoloji yokulinganisa isantya se-photoelectric yendabuko, i-tachometer ye-inductive ayifuni ukufaka i-sensor ye-photoelectric, akukho kwandiso kwe-motor shaft, kwaye ingasetyenziselwa kumashishini epompo yamanzi kunye namanye amashishini apho kunzima ukufaka izinzwa.
