Uchwepheshe Wezimoto Ezingenawo Umgogodla Ucacisa Umehluko Obalulekile Phakathi Kwe-Locked-Rotor Torque Ne-Starting Torque Kumhlahlandlela Omusha Wobuchwepheshe

Umhlahlandlela uqala ngokuphendula umbuzo ovame ukuphakanyiswa onjiniyela bokuklama: Njengoba kokubili i-torque ekhiyiwe kanye ne-torque yokuqala kwenzeka ngesivinini esingu-zero, ingabe kuyipharamitha efanayo? Ngokwezinga le-IEC 60050-114 (elihambisana ne-GB/T 2900.25), izincazelo zembula umehluko obalulekile othinta ngqo izibalo zokusebenza kwezimoto.

I-torque ekhiyiwe ichazwa ngokuthi “i-torque encane elinganisiwe ekhiqizwa lapho injini inikwa amandla ngemvamisa elinganisiwe kanye ne-voltage lapho i-rotor ivaliwe kuzo zonke izikhundla ze-angular.” Ngokuphambene nalokho, i-torque yokuqala “i-torque ye-electromagnetic minus friction kanye ne-windage torque phakathi nesikhathi sokuqala kusukela esivinini se-zero kuya esivinini somthwalo.”

Iphuzu vs. Inqubo: Umehluko Oyisisekelo

Umehluko oyinhloko usekelwe emvelweni wawo oyisisekelo. I-torque ekhiyiwe-rotor imelela iphuzu ledatha elilodwa, elithile—inani eliphansi eliqinisekisiwe esimweni esibi kakhulu. Lokhu kucaciswa okulondoloziwe kubhekisela ekushintsheni kwe-torque okubangelwa ama-harmonics, ukwakheka kwe-slot, kanye ne-rotor magnetic circuit geometry, okubaluleke kakhulu kuma-motor asynchronous esigaba esisodwa lapho amasimu ajikelezayo angewona ajikelezayo angadala i-torque ripple ebalulekile.

I-torque yokuqala, nokho, ichaza inqubo yonke, hhayi inani elilodwa. Iveza umugqa oqhubekayo wamanani e-torque ngokuhamba kwesikhathi kanye nokuqhubeka kwesivinini. Ngenkathi i-torque eku-zero RPM ngqo ingasondela ngenani le-locked-rotor lama-motor aklanywe kahle lapho ukulahlekelwa kokungqubuzana kuncane khona, uhlaka lomqondo luhlala luhlukile.

Imiphumela Ewusizo Yezicelo Zemoto Engenawo Umgogodla

Kubasebenzisi bezimoto ezingenamgogodla, lo mehluko ungaphezu kwezemfundo. Ukucaciswa kwe-torque ekhiyiwe njengenani eliphansi elilinganisiwe kusebenza njengesivikelo sokuthembeka—kuqinisekisa ukuthi ngisho nangaphansi kwezimo zokuguquguquka kwe-torque ezimbi kakhulu, umkhiqizo ophansi kakhulu wemoto uzoqhubeka udlule izidingo zomthwalo wohlelo lokusebenza, okuqinisekisa ukuqala okuthembekile njalo.

“Yingakho amashidi ethu edatha enjini angenawo umgogodla echaza i-torque ekhiyiwe enemingcele elondolozayo,” kuchaza uDkt. Wang, iSikhulu Esiphezulu Sezobuchwepheshe eSinbad Motor. “Ezinhlelweni zokusebenza zedivayisi yezokwelapha lapho ukuqala okuhlulekile akuyona inketho, ukuqonda ukuthi le pharamitha imelela ubuncane obuqinisekisiwe—hhayi inani elimaphakathi noma elijwayelekile—kuvumela onjiniyela ukuthi baklame ngokuzethemba.”

Umhlahlandlela uphetha ngokuthi nakuba umkhuba wemboni yasendulo wawuvame ukusebenzisa amagama ngokushintshana, ubunjiniyela bokunemba bufuna ukucaciswa. Abaklami kufanele babhekisele ku-"i-torque yokuqala ngesivinini esingu-zero" noma "i-torque yokuqala encane" (iphuzu eliphansi kakhulu lejika, okungenzeka lingenzeki ngesivinini esingu-zero) ukuze kukhulunywe ngokusobala.

Mayelana neSinbad Motor

I-Sinbad Motor ingumkhiqizi ohamba phambili wama-motor e-DC angenawo umgogodla asebenza kahle kakhulu, eletha izixazululo zama-motor ezenziwe ngokwezifiso zezinhlelo zokusebenza zezokwelapha, zezindiza, zamarobhothi, kanye nezokuzenzakalela kwezimboni. Ngamakhono okuklama athuthukisiwe kanye nezinqubo zokuhlola ezihambisana ne-IEC, inkampani inikeza ama-motor ahlangabezana nezimfuneko ze-torque nokuthembeka ezifunwa kakhulu.
