Ziziphi iimpawu zemoto yokungafuni ukutshintshelwa?

Ukutshintsha kwemotor yokungafuni ukutshitsha yimoto elawulwa ngesantya ephuhliswe emva kwemoto yeDC kunye nebrushless DC motor, kwaye isetyenziswa kakhulu kwizixhobo zasekhaya, inqwelomoya, i-aerospace, i-elektroniki, oomatshini kunye nezithuthi zombane. I-motor ye-reluctance etshintshiweyo inesakhiwo esilula; i-motor inesakhiwo esilula kunye neendleko eziphantsi, kwaye ingasetyenziselwa ukusebenza ngesantya esiphezulu. Ulwakhiwo lwe-motor ye-reluctance etshintshiweyo ilula kuneye-squirrel-cage induction motor. I-rotor yayo inamandla amakhulu omatshini kwaye ingasetyenziselwa ukusebenza ngokukhawuleza (njengamashumi amawaka eenguqu ngomzuzu).

Ziziphi iimpawu zokutshintsha kwemoto yokungafuni

Utshintshe injini yokungafuniyimoto elawulwa ngesantya ephuhliswe emva kwemoto ye-DC kunye ne-brushless DC motor, kwaye isetyenziswa kakhulu kwizixhobo zasekhaya, inqwelomoya, i-aerospace, i-elektroniki, oomatshini kunye nezithuthi zombane.

Ezona mpawu ziphambili zenkqubo yokulawula isantya sokutshintsha kwesantya semoto:
Ulwakhiwo olulula; i-motor inesakhiwo esilula kunye neendleko eziphantsi, kwaye ingasetyenziselwa ukusebenza ngesantya esiphezulu. Ulwakhiwo lwe-motor ye-reluctance etshintshiweyo ilula kuneye-squirrel-cage induction motor. I-rotor yayo inamandla amakhulu omatshini kwaye ingasetyenziselwa ukusebenza ngokukhawuleza (njengamashumi amawaka eenguqu ngomzuzu). Ngokubhekiselele kwi-stator, ine-windings embalwa egxininiswe kuphela, ngoko kulula ukwenza kunye nesakhiwo se-insulation silula.

Ukuthembeka kwesekethe yemoto etshintshileyo yokungafuni; isiphaluka samandla silula kwaye sithembekile. Ekubeni ulwalathiso lwe-torque ye-motor alunanto yakwenza nolwalathiso lwangoku olujikajikayo, oko kukuthi, inqanaba elinye kuphela elifunekayo langoku, isekethe yamandla inokuqonda iswitshi enye yamandla ngesigaba ngasinye. Xa kuthelekiswa ne-asynchronous motor windings efuna i-bidirectional current, i-PWM inverter power circuit ebabonelelayo ifuna izixhobo ezibini zamandla ngesigaba ngasinye. Ke ngoko, inkqubo yokulawula isantya semotor etshintshileyo ifuna izinto ezincinci zamandla kunye nolwakhiwo olulula lwesekethe kunendlela yokuguquguqula i-pulse wide modulation inverter power supply circuit. Ukongeza, kwisekethe yamandla ye-PWM inverter, iityhubhu ezimbini zokutshintsha amandla kwingalo yebhulorho nganye zihamba ngokuthe ngqo kwicala lonikezelo lwamandla e-DC, ekunokwenzeka ukuba kubangele isekethe emfutshane ngokuthe ngqo ukutshisa isixhobo samandla. Nangona kunjalo, isixhobo ngasinye sokutshintsha umbane kwinkqubo yokulawula isantya semoto sidityaniswa ngokuthe ngqo kuthotho kunye ne-motor winding, ethi ithintele ngokusisiseko isenzeko sesekethe emfutshane ethe ngqo. Ngoko ke, isiphaluka sokukhusela isiphaluka sonikezelo lwamandla kwinkqubo yokulawula isantya sokutshintshwa kwemoto yokungafuni ukwenza lula, ixabiso liyancitshiswa, kwaye ukuthembeka kuphezulu.
