Ziziphi iindlela zokunciphisa umbane wokuqala wemoto?

1. Ukuqala ngokuthe ngqo

Ukuqalisa ngokuthe ngqo yinkqubo yokudibanisa ngokuthe ngqoi-statorukujika kwe-injini yombaneukuya kumbane kunye nokuqala ngevolthi elinganisiweyo. Ineempawu ze-torque ephezulu yokuqalisa kunye nexesha elifutshane lokuqalisa, kwaye ikwayindlela yokuqalisa elula, engabizi kakhulu, kwaye ithembekile. Xa uqala ngevolthi epheleleyo, umbane uphezulu kwaye i-torque yokuqalisa ayinkulu, okwenza kube lula ukuyisebenzisa kwaye ikhawuleze ukuqala. Nangona kunjalo, le ndlela yokuqalisa ineemfuno eziphezulu zomthamo wegridi kunye nomthwalo, kwaye ifanelekile kakhulu kwiimoto zokuqalisa ezingaphantsi kwe-1W.

2.Ukuqala kokumelana nochungechunge lweemoto

Ukuqala kokumelana nochungechunge lweemoto yindlela yokunciphisa ukuqala kwe-voltage. Ngexesha lenkqubo yokuqalisa, i-resistor iqhagamshelwe kuthotho kwisekethe yokujija ye-stator. Xa umbane wokuqalisa udlula, kuveliswa i-voltage drop kwi-resistor, nto leyo enciphisa i-voltage esetyenziswa kwi-voltage.i-statorukujikajika. Oku kunokufezekisa injongo yokunciphisa umsinga wokuqalisa.

3.Ukuqala kwe-self coupling transformer

Ukusebenzisa i-multi tap voltage reduction ye-autotransformer akunakuhlangabezana neemfuno zokuqalisa umthwalo owahlukileyo kuphela, kodwa kunokufumana i-torque enkulu yokuqala. Yindlela eqhelekileyo yokuqalisa ukunciphisa i-voltage yokuqalisa ii-motors ezinkulu. Inzuzo yayo enkulu kukuba i-torque yokuqala inkulu. Xa i-winding tap iku-80%, i-torque yokuqala inokufikelela kwi-64% ye-torque yokuqala ngqo, kwaye i-torque yokuqala inokulungiswa nge-tap. Iakhawunti esemthethweni ethi "Mechanical Engineering Literature", isikhululo sepetroli sobunjineli!

4. Ukuqala kokunciphisa uxinzelelo lweDelta yeenkwenkwezi

Kwikheyiji yesquirrel enenjini engangqamananga esebenza ngendlela eqhelekileyoi-statorUkujija okudityaniswe ngendlela engxantathu, ukuba ukujija kwe-stator kudityaniswe ngendlela yenkwenkwezi ngexesha lokuqalisa kuze kudityaniswe ngendlela engxantathu emva kokuqalisa, kunokunciphisa umsinga wokuqala kwaye kunciphise impembelelo yawo kwigridi yamandla. Le ndlela yokuqalisa ibizwa ngokuba kukuqala kwe-star delta decompression, okanye ukuqala nje kwe-star delta (y&starting).

Xa usebenzisa indlela yokuqalisa i-star delta, umsinga wokuqala usisixa sesithathu kuphela sendlela yokuqala yokuqalisa ngqo usebenzisa indlela yokudibanisa unxantathu. Xa uqala i-star delta, umsinga wokuqala usisixa sezihlandlo ezi-2-2.3 kuphela. Oku kuthetha ukuba xa usebenzisa i-star delta yokuqala, i-torque yokuqala ikwancitshiswa ukuya kwisinye sesithathu sendlela eyayiyiyo xa uqala ngokuthe ngqo usebenzisa indlela yokudibanisa unxantathu.

Ifanelekile kwiimeko apho kungekho mthwalo okanye umthwalo ulula oqalayo. Kwaye xa ithelekiswa nayo nayiphi na enye i-vacuum starter, ulwakhiwo lwayo lolona lulula kwaye ixabiso likwalelona liphantsi.

Ukongeza, indlela yokuqalisa i-star delta ikwanenzuzo, yokuba xa umthwalo ulula, inokuvumela imoto ukuba isebenze phantsi kwendlela yokudibanisa i-star. Kule ndawo, i-torque kunye nomthwalo olinganisiweyo zinokulinganiswa, nto leyo enokuphucula ukusebenza kakuhle kwemoto kwaye yonge ukusetyenziswa kombane.

5. Ukuqalisa kwesiguquli seFrequency (ukuqala okuthambileyo)

 Isiguquli seefrikhwensi sesona sixhobo sokulawula iimoto siphucuke kakhulu kwezobuchwepheshe, esisebenza ngokupheleleyo, nesisebenzayo kwicandelo lolawulo lweemoto zanamhlanje. Silungisa isantya kunye ne-torque yemoto ngokutshintsha i-frequency yegridi yamandla. Ngenxa yokubandakanyeka kwetekhnoloji ye-elektroniki yamandla kunye netekhnoloji ye-microcomputer, iindleko ziphezulu kwaye neemfuno zeengcali zokulungisa nazo ziphezulu. Ke ngoko, isetyenziswa kakhulu kwiindawo ezifuna ukulawulwa kwesantya kunye neemfuno zolawulo lwesantya esiphezulu.
