Umehluko phakathi kwe-DC motor kanye ne-AC motor

Uma kuziwa kuma-motor kagesi, kunezinhlobo ezimbili eziyinhloko: ama-motor amanje (DC) kanyealternating current (AC) motors. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili kubalulekile ekukhetheni injini efanele yohlelo oluthile.

Isebenza kanjani

Amamotho e-DC asebenza ngezimiso zozibuthe kagesi, ahlinzeka amandla akhona ngqo kuma-motor windings ukuze akhiqize inkambu kazibuthe esebenzisana nozibuthe unomphela noma ama-winding field. Lokhu kusebenzisana kudala ukunyakaza okujikelezayo. Ngokuphambene, amamotho e-AC asebenzisa amandla ashintshayo futhi ashintsha indlela ngezikhathi ezithile. Uhlobo oluvame kakhulu yi-i-induction motor, ethembele ekwenziweni kukazibuthe kagesi ukukhiqiza ukunyakaza, lapho i-stator ikhiqiza inkambu yakazibuthe ezungezayo engenisa i-current ku-rotor.

Izinzuzo kanye Nemibi

I-DC Motor:

inzuzo:

- Ukulawula Isivinini: Amamotho e-DC ahlinzeka ngokulawula kwejubane okuhle kakhulu, okuwenza alungele izinhlelo zokusebenza ezidinga isivinini esiguquguqukayo.

- I-Torque Yokuqala Ephezulu: Ihlinzeka nge-torque ephezulu yokuqala, ezuzisa izinhlelo zokusebenza zomthwalo osindayo.

ukushiyeka:

- Ukunakekela: Amamotho e-DC adinga ukunakekelwa okwengeziwe njengoba amabhulashi kanye nezihambisi ziguga ngokuhamba kwesikhathi.

- Izindleko: Ngokuvamile, zibiza kakhulu kunamamotho e-AC, ikakhulukazi ezisetshenziswa zamandla aphezulu.

I-AC Motor:

inzuzo:

- Ukuqina: Amamotho e-AC ngokuvamile ahlala isikhathi eside futhi adinga ukulungiswa okuncane ngoba awanawo amabhulashi.

- Ukusebenza Kwezindleko: Ngokuvamile abiza kakhulu ekusetshenzisweni kwamandla aphezulu futhi asetshenziswa kakhulu kuzilungiselelo zezimboni.

 ukushiyeka:

- Ukulawulwa Kwesivinini: Amamotho e-AC anokulawula ijubane okusebenza kahle kakhulu kunamamotho e-DC, okuwenza angalungeli kakhulu izinhlelo zokusebenza ezidinga ukulawulwa kwejubane okunembayo.

- I-Torque yokuqala: Ivamise ukuba netorque ephansi yokuqala, okungase kube umkhawulo kwezinye izinhlelo zokusebenza.

Ngakho-ke ukuzimisela kokugcina kwemoto kagesi kuncike ezidingweni ezithile zohlelo lokusebenza, kufaka phakathi izici ezinjengokulawula isivinini, ukulungiswa. Kokubili i-3 isigaba sikagesi ac motorfuthi injini ye-DC inamandla azo ngakho ukuqonda lo mehluko kungakusiza wenze izinqumo ezinolwazi ngokusebenza kahle.
