Kunezinhlobo ezimbili zama-drive motors avame ukusetshenziswa ezimotweni zamandla amasha: ama-magnetic synchronous motors ahlala njalo kanye nama-AC asynchronous motors. Izimoto eziningi ezintsha zamandla zisebenzisa izinjini ezivumelanisa uzibuthe, futhi inombolo encane kuphela yezimoto ezisebenzisa ama-AC asynchronous motors.
Njengamanje, kunezinhlobo ezimbili zama-drive motors avame ukusetshenziswa ezimotweni zamandla amasha: ama-motor synchronous kazibuthe angapheli kanye nama-AC asynchronous motors. Izimoto eziningi ezintsha zamandla zisebenzisa izinjini ezivumelanisa uzibuthe, futhi inombolo encane kuphela yezimoto ezisebenzisa ama-AC asynchronous motors.
Umgomo wokusebenza we-magnetic synchronous motor unomphela:
Ukunika amandla i-stator ne-rotor kukhiqiza inkambu kazibuthe ezungezayo, okubangela ukunyakaza okuhlobene phakathi kwakho kokubili. Ukuze i-rotor isike imigqa yensimu kazibuthe futhi ikhiqize yamanje, isivinini sokuzungezisa sidinga ukuba sihambe kancane kunesivinini sokuzungezisa senkambu yakazibuthe ezungezayo ye-stator. Njengoba lezi zimbili zihlala zisebenza ngokulinganayo, zibizwa ngama-asynchronous motors.

Njengoba lezi zimbili zihlala zisebenza ngokulinganayo, zibizwa ngama-asynchronous motors. Njengoba kungekho uxhumano lwemishini phakathi kwe-stator ne-rotor, akulula nje ngesakhiwo futhi kulula ngesisindo, kodwa futhi kunokwethenjelwa ekusebenzeni futhi kunamandla aphezulu kunama-DC motors.
Amamotho anobungane ozibuthe ahlala njalo kanye namamotho asynchronous e-AC ngayinye inezinzuzo zayo kanye nokubi ezimweni ezihlukene zohlelo lokusebenza. Okulandelayo ezinye iziqhathaniso ezivamile:
1. Ukusebenza kahle: Ukusebenza kahle kwe-synchronous motor ehlala njalo kazibuthe ngokuvamile kuphakeme kunaleyo ye-AC asynchronous motor ngoba ayidingi i-magnetizing current ukukhiqiza inkambu kazibuthe. Lokhu kusho ukuthi ngaphansi kokukhishwa kwamandla okufanayo, injini ye-synchronous kazibuthe unomphela idla amandla amancane futhi inganikeza ibanga elide lokuhamba.
2. Ukuminyana kwamandla: Ukuminyana kwamandla kazibuthe unomphela we-synchronous motor ngokuvamile kuphakeme kunaleyo ye-AC asynchronous motor ngoba i-rotor yayo ayidingi ama-windings ngakho-ke ingaba compact kakhudlwana. Lokhu kwenza izinjini ezivumelanisiwe zikazibuthe ezihlala njalo zibe nenzuzo enkulu ezinhlelweni ezibambezeleke esikhaleni njengezimoto zikagesi nama-drones.
3. Izindleko: Izindleko zama-AC asynchronous motors ngokuvamile ziphansi kunama-motor synchronous kazibuthe unomphela ngoba isakhiwo sayo se-rotor silula futhi asidingi ozibuthe unomphela. Lokhu kwenza ama-asynchronous motors e-AC abe nenzuzo enkulu kwezinye izinhlelo zokusebenza ezingazweli izindleko, njengezinto ezisetshenziswayo zasendlini nemishini yezimboni.
4. Ukulawula inkimbinkimbi: Ukulawula inkimbinkimbi yama-motor synchronous kazibuthe unomphela ngokuvamile kuphakeme kunaleyo yama-asynchronous motors e-AC ngoba kudinga ukulawulwa okuqondile kwenkundla kazibuthe ukuze kuzuzwe ukusebenza kahle okuphezulu kanye nokuminyana kwamandla aphezulu. Lokhu kudinga ama-algorithms okulawula ayinkimbinkimbi kanye ne-electronics, ngakho kwezinye izinhlelo zokusebenza ezilula ama-asynchronous motors angase afaneleke kakhulu.
Kafushane, amamotho ayizibuthe angama-synchronous motors kanye nama-asynchronous motors e-AC ngayinye inezinzuzo zayo kanye nokubi, futhi idinga ukukhethwa ngokuya ngezimo nezidingo ezithile zohlelo lokusebenza. Kuzicelo ezisebenza kahle kakhulu nezinamandla amakhulu njengezimoto zikagesi, ama-motor synchronous azibuthe unomphela avame ukuba nenzuzo kakhulu; kuyilapho kwezinye izinhlelo zokusebenza ezizwelayo izindleko, amamotho asynchronous e-AC angase afaneleke kakhulu.
Amaphutha ajwayelekile amamotho amasha wokushayela imoto yamandla afaka okulandelayo:
- Iphutha le-insulation: Ungasebenzisa imitha yokushisa ukuze ulungise ama-volts angu-500 futhi ulinganise izigaba ezintathu ze-motor uvw. Ivelu yokwahlukanisa evamile iphakathi kuka-550 megohms kanye ne-infinity.
- Ama-splines agugile: Injini iyaduma, kodwa imoto ayiphenduli. Hlukanisa injini ukuze uhlole ngokuyinhloko izinga lokuguga phakathi kwamazinyo e-spline namazinyo omsila.
- Izinga lokushisa eliphakeme lezimoto: ihlukaniswe yaba izimo ezimbili. Esokuqala izinga lokushisa eliphezulu langempela elibangelwa iphampu yamanzi engasebenzi noma ukuntuleka kwesipholile. Okwesibili kubangelwa inzwa yokushisa ye-motor yonakaliswa, ngakho-ke kuyadingeka ukusebenzisa uhla lokumelana lwe-multimeter ukukala izinzwa ezimbili zokushisa.
- Ukwehluleka kwesixazululo: ihlukaniswe yaba izimo ezimbili. Okokuqala ukuthi isilawuli se-elekthronikhi sonakalisiwe futhi lolu hlobo lwephutha luyabikwa. Okwesibili kungenxa yomonakalo wangempela wesixazululi. I-sine, i-cosine ne-excitation yesixazululi se-motor nakho kukalwa ngokuhlukana kusetshenziswa izilungiselelo zokuphikisa. Ngokuvamile, amanani okumelana ne-sine ne-cosine asondelene kakhulu nama-ohms angama-48, okuyi-sine ne-cosine. Ukumelana nenjabulo kuyahluka ngama-ohm amaningi, futhi injabulo ingu-≈ 1/2 sine. Uma isixazululi sehluleka, ukumelana kuzohluka kakhulu.
Ama-splines enjini entsha yokushayela imoto yamandla agqokile futhi angalungiswa ngezinyathelo ezilandelayo:
1. Funda i-engeli yesixazululi senjini ngaphambi kokuyilungisa.
2. Sebenzisa okokusebenza ukuze ulungise uziro isixazululi ngaphambi kokuhlanganisa.
3. Ngemva kokuqedwa kokulungiswa, hlanganisa injini nokuhlukanisa bese uhambisa imoto. #electricdrivecyclization# #electricmotorconcept# #motorsinnovationtechnology# # motorprofessionalknowledge# # motorovercurrent# #深蓝superelectricdrive#
