Mumakore achangopfuura, magineti echigarire akananga dhiraivha motors akafambira mberi zvakanyanya uye anonyanya kushandiswa mukutakura-kumhanya mitoro, senge mabhandi ekutakurisa, musanganiswa, waya yekudhirowa michina, yakaderera-inomhanya pombi, kutsiva electromechanical masisitimu anoumbwa neakakwira-kumhanya motors uye mechanic. kuderedza nzira. Iyo yekumhanyisa huwandu hwemota kazhinji iri pasi pe500rpm. Permanent magineti yakananga dhiraivha motors inogona kunyanya kukamurwa kuita maviri ezvimiro mafomu: yekunze rotor uye yemukati rotor. Rotor yekunze inogara magineti yakananga dhiraivha inonyanya kushandiswa mumabhandi maconveyors.
Mukugadzira uye kushandiswa kwechigarire magineti yakananga dhiraivha mota, zvinofanirwa kucherechedzwa kuti yekusingaperi magineti yakananga dhiraivha haina kukodzera kunyanya yakaderera kubuda kumhanya. Kana mitoro yakawanda mukati50r / min inotyairwa nemotokari yakananga, kana simba richiramba riripo, rinoita kuti torque yakakura, inotungamira kumitengo yakakwira mota uye kuderera kwekuita. Kana simba nekumhanya zvatemwa, zvinodikanwa kuenzanisa kugona kwehupfumi kwemusanganiswa weakananga dhiraivha mota, yakakwira kumhanya mota, uye magiya (kana imwe kukurumidza kuwedzera nekudzikira kwemakanika zvimiro). Parizvino, ma turbines emhepo ari pamusoro pe15MW uye pazasi 10rpm zvishoma nezvishoma ari kutora semi yakananga dhiraivha chirongwa, achishandisa magiya kuti awedzere kumhanya kwemota zvakakodzera, kuderedza mutengo wemota, uye pakupedzisira kudzikisa mitengo yehurongwa. Izvo zvinoshandawo kune magetsi emagetsi. Naizvozvo, kana kumhanya kuri pazasi pe100 r/min, kufunga nezvehupfumi kunofanirwa kunyatsotariswa, uye semi direct drive scheme inogona kusarudzwa.
Yechigarire magineti yakananga dhiraivha mota dzinowanzo shandisa pamusoro yakamisikidzwa isingaperi magineti rotor kuwedzera torque density uye kuderedza kushandiswa kwezvinhu. Nekuda kweiyo yakaderera kutenderera kumhanya uye diki centrifugal simba, hazvifanirwe kushandisa yakavakirwa-mukati magineti rotor chimiro. Kazhinji, mabhawa ekumanikidza, simbi isina simbi maoko, uye fiberglass ekudzivirira maoko anoshandiswa kugadzirisa nekuchengetedza rotor zvachose magineti. Nekudaro, mamwe mamotor ane akavimbika epamusoro zvinodiwa, akati wandei nhamba dzedanda, kana akakwira vibrations anoshandisa akavakirwa-mukati magineti rotor zvimiro.
Iyo yakaderera-kumhanya yakananga dhiraivha mota inofambiswa neinoshandura frequency. Kana iyo pole nhamba dhizaini yasvika padanho repamusoro, kumwe kudzikiswa kwekumhanya kunokonzeresa yakaderera frequency. Kana kuwanda kweiyo frequency converter kwakadzikira, basa rekutenderera kwePWM rinodzikira, uye waveform haina kunaka, izvo zvinogona kutungamirira kukuchinja uye kusagadzikana kumhanya. Saka kutonga kweakanyanya kuderera kumhanyisa dhiraivha mota zvakare kwakaoma. Parizvino, mamwe ma-ultra-low speed motors anotora magnetic field modulation motor scheme kuti ashandise yakakwira kutyaira frequency.
Yakaderera yekumhanya inogara magineti yakananga dhiraivha motors inogona kunyanya kuve yakatonhodzwa nemhepo uye mvura yakatonhodzwa. Kutonhora kwemhepo kunonyanya kutora iyo IC416 yekutonhodza nzira yemafeni akazvimirira, uye kutonhora kwemvura kunogona kuve kutonhora kwemvura (IC.71W), iyo inogona kutsanangurwa maererano ne-on-saiti mamiriro. Mumvura inotonhorera modhi, iyo yekupisa inorema inogona kugadzirwa yakakwira uye chimiro chakanyanya compact, asi kutarisisa kunofanirwa kubhadharwa kuwedzera ukobvu hwemagineti asingagumi kudzivirira overcurrent demagnetization.
Kune yakaderera-kumhanya yakananga dhiraivha masisitimu ane zvinodiwa zvekumhanya uye chinzvimbo chechokwadi chekudzora, zvinodikanwa kuwedzera ma sensors enzvimbo uye kutora nzira yekudzora ine ma sensors enzvimbo; Uye zvakare, kana paine yakakwira torque inodiwa panguva yekutanga, nzira yekudzora ine sensor yenzvimbo inodiwa zvakare.
Kunyangwe kushandiswa kwechigarire magineti yakananga dhiraivha motors kunogona kubvisa iyo yekutanga yekudzikisa mashandiro uye kuderedza mari yekugadzirisa, dhizaini isingaite inogona kutungamira kumitengo yakakwira yekusingaperi magineti yakananga dhiraivha motors uye kudzikira kwekuita kwesystem. Kazhinji kutaura, kuwedzera dhayamita yeanogara magineti akananga dhiraivha motors kunogona kuderedza mutengo payuniti torque, saka yakananga dhiraivha mota inogona kugadzirwa kuita dhisiki hombe ine dhayamita yakakura uye ipfupi stack kureba. Zvisinei, kunewo miganhu yekuwedzera kwedhayamita. Iyo yakakura yakawandisa dhayamita inogona kuwedzera mutengo weiyo casing uye shaft, uye kunyange zvimiro zvekugadzira zvichapfuura zvishoma nezvishoma mutengo wezvigadzirwa zvinoshanda. Saka kugadzira yakananga dhiraivha mota kunoda kukwidziridza kureba kusvika kudhayamita reshiyo kudzikisa mutengo wese wemota.
Chekupedzisira, ndinoda kusimbisa kuti magineti echigarire akananga dhiraivha motors achiri ma frequency converter driven motors. Iyo simba chinhu chemota inokanganisa ikozvino padivi rekubuda reiyo frequency converter. Chero bedzi iri mukati mehuwandu hwehuwandu hweiyo frequency converter, iyo simba chinhu ine diki mhedzisiro pakuita uye haizokanganisa iyo simba chinhu padivi regidhi. Naizvozvo, iyo simba chinhu dhizaini yemota inofanirwa kuyedza kuve nechokwadi chekuti yakananga dhiraivha inoshanda muMTPA modhi, iyo inoburitsa yakanyanya torque neishoma iripo. Chikonzero chakakosha ndechekuti frequency yeakananga dhiraivha motors kazhinji yakaderera, uye kurasikirwa kwesimbi kwakadzikira zvakanyanya kupfuura kurasikirwa kwemhangura. Kushandisa MTPA nzira kunogona kuderedza kurasikirwa kwemhangura. Technicians haafanire kufurirwa neyechinyakare grid yakabatana asynchronous motors, uye hapana chikonzero chekutonga kushanda kwemota zvichibva pahukuru hwazvino padivi remota.
Anhui Mingteng Permanent-Magnetic Machinery &Electrical Equipment Co., Ltd ibhizinesi remazuva ano repamusoro-soro rinobatanidza kutsvagisa nekusimudzira, kugadzira, kutengesa, uye sevhisi yekusingaperi magineti mota. Izvo zvakasiyana-siyana zvechigadzirwa uye zvinyorwa zvakakwana. Pakati pavo, yakaderera-kumhanya yakananga dhiraivha inogara magineti motors (7.5-500rpm) anoshandiswa zvakanyanya mukuremerwa kwemaindasitiri senge mafeni, mabhandi anotakura, pombi dzepombi, uye zvigayo mune simende, zvekuvaka, migodhi yemarasha, peturu, simbi, uye mamwe maindasitiri. , nemamiriro akanaka ekushanda.
