Ayini amandla okushayela kwe-brushless motor?
Nazi izindlela ezimbalwa zokushayela i-brushless DC motor.Ezinye izimfuneko zesistimu eziyisisekelo zibalwe ngezansi: a.Ama-transistors kagesi: Lawa ngokuvamile ama-MOSFET kanye nama-IGBT akwazi ukumelana nama-voltage aphezulu (ahambisana nezidingo zenjini).Izinto zikagesi eziningi zasendlini zisebenzisa izinjini ezikhiqiza amandla angu-3/8 amahhashi (1HP = ...Funda kabanzi -
Ubuchwepheshe bemikhono yokunciphisa ukushisa buthuthukisa kakhulu ikhono lokubamba nokuvikela omazibuthe bezimoto abangenamabhulashi
Ukushisa kwe-multilayer shwabanisa amashubhu anokumelana okuphezulu komshini kanye ne-thermal coefficient ephezulu ukuze kuvikelwe futhi kuvikelwe ama-rotor motors e-brushless, kulinganisa zonke izinhlobo zamandla aphakathi nendawo asetshenziswa kuzibuthe ezihlala njalo.Ayikho ingozi yokuqhekeka noma ukulimaza omagnethi baphakade ngesikhathi ...Funda kabanzi -
Yimaphi amapharamitha athinta isivinini esikhulu kanye nenani eliphakeme lamanje kumathuluzi wamandla ezimboni?
Amathuluzi wamandla ezimboni asebenza ngebhethri ngokuvamile asebenza ngamavoltheji aphansi (12-60 V), futhi amamotho e-DC abhulashiwe ngokuvamile ayinketho enhle yokonga, kodwa amabhulashi anqunyelwe ugesi (amanje ahlobene ne-torque) kanye nemishini (ehlobene nesivinini) Ukungqubuzana. ) isici sizodala ukuguga, ngakho-ke inani le-cycl...Funda kabanzi -
Okuqukethwe okuyisisekelo kokukhetha kwezimoto
Okuqukethwe okuyisisekelo okudingekayo ekukhethweni kwezimoto yilezi: uhlobo lomthwalo oshayelwa, amandla akaliwe, i-voltage elinganiselwe, isivinini esilinganisiwe, nezinye izimo.1. Uhlobo lomthwalo ozoshayelwa lushiwo ngokuphambene kusukela ezicini zemoto.Ama-Motor angahlukaniswa kalula abe ama-DC motors kanye nama-AC motors, futhi i-AC igcwele ...Funda kabanzi -
Amandla kagesi aphezulu kanye nama-low-voltage motors, umehluko obalulekile enqubweni yokukhiqiza
Ngokombono wokusetshenziswa, umehluko phakathi kwama-motor voltage aphezulu naphansi umehluko ku-voltage elinganiselwe phakathi kokubili, kodwa ngenqubo yokukhiqiza, umehluko phakathi kokubili usemkhulu kakhulu.Ngenxa yomehluko ku-voltage elinganiselwe ye-motor, umehluko ku-clean ...Funda kabanzi -

Icala Lokuhluleka Kwekhwalithi: I-Shaft Currents iyi-Hacker ye-Motor Bearing Systems
I-Shaft current iwumbulali omkhulu wama-motor frequency motors, ama-motor amakhulu, ama-voltage aphezulu namajeneretha, futhi iyingozi kakhulu ohlelweni lokuthwala izinjini.Kunezimo eziningi zokuhluleka kwesistimu yokuthwala ngenxa yezinyathelo zokuphepha zamanje ze-shaft ezinganele.I-shaft current iyisici...Funda kabanzi -
Indlela isikhathi nezinga lokushisa okuthinta ngayo ukuzinza kozibuthe unomphela
Ikhono likakazibuthe unomphela lokusekela insimu yamagnetic yangaphandle kungenxa ye-crystal anisotropy ngaphakathi kwempahla kazibuthe "evala" izizinda ezincane ezizibuthe endaweni.Uma i-magnetization yokuqala isimisiwe, lezi zikhundla zihlala zifana kuze kube yilapho amandla angaphezu kwe-lo...Funda kabanzi -
Ikhuluma ngobudlelwano phakathi kwesiguquli semvamisa nemoto
Sekuwumkhuba ongeke wahlehliswa ukushayela injini nge-inverter.Enqubweni yokusetshenziswa kwangempela, ngenxa yobudlelwano obungenangqondo bokuqhathanisa phakathi kwe-inverter ne-motor, ezinye izinkinga zivame ukwenzeka.Lapho ukhetha i-inverter, kufanele uqonde ngokugcwele izici zomthwalo we-t ...Funda kabanzi -
