Zotsatira za Iron Core Stress pa Magwiridwe a Permanent Magnet Motors

Zotsatira za Iron Core Stress pa Magwiridwe aPermanent Magnet Motors

Kukula mwachangu kwachuma kwalimbikitsanso ukadaulo wamakampani okhazikika amagetsi amagetsi, kuyika patsogolo zofunika kwambiri pamachitidwe okhudzana ndi magalimoto, miyezo yaukadaulo, komanso kukhazikika kwa magwiridwe antchito. Kuti ma motors okhazikika a maginito akule m'malo ambiri ogwiritsira ntchito, ndikofunikira kulimbikitsa magwiridwe antchito mbali zonse, kuti mawonekedwe onse ndi zisonyezo zamagalimoto azitha kufika pamlingo wapamwamba.

Kwa maginito okhazikika amagetsi, pachimake chitsulo ndi gawo lofunikira kwambiri mkati mwa mota. Pakusankha zida zapakati pachitsulo, ndikofunikira kuganizira mozama ngati maginito a maginito amatha kukwaniritsa zofunikira za injini yokhazikika yamagetsi. Nthawi zambiri, Chitsulo chamagetsi chimasankhidwa kukhala chinthu chofunikira kwambiri pamakina amagetsi okhazikika, ndipo chifukwa chachikulu ndikuti Chitsulo chamagetsi chimakhala ndi maginito abwino.

Kusankhidwa kwa zida zoyambira zamagalimoto kumakhudza kwambiri magwiridwe antchito onse komanso kuwongolera mtengo wamagetsi okhazikika amagetsi. Panthawi yopanga, kusonkhanitsa, ndikugwira ntchito mokhazikika kwa maginito okhazikika a maginito, zovuta zina zimapangika pachimake. Komabe, kukhalapo kwa kupsinjika kumakhudza mwachindunji maginito a chitsulo chamagetsi, kupangitsa kuti maginito azitha kutsika mosiyanasiyana, motero magwiridwe antchito amagetsi okhazikika atsika, ndikuwonjezera kutayika kwagalimoto.

Pakupanga ndi kupanga maginito okhazikika amagetsi, zofunikira pakusankha ndikugwiritsa ntchito zida zikukulirakulira, ngakhale kuyandikira malire ndi kuchuluka kwa magwiridwe antchito. Monga maziko a maginito okhazikika a maginito, Chitsulo chamagetsi chiyenera kukwaniritsa zofunikira kwambiri pa matekinoloje ogwiritsira ntchito komanso kuwerengera molondola kutayika kwachitsulo kuti zikwaniritse zosowa zenizeni.

Njira yachikhalidwe yamagalimoto yomwe imagwiritsidwa ntchito powerengera ma elekitiromagineti a Chitsulo chamagetsi mwachiwonekere sicholondola, chifukwa njira zodziwika bwino izi ndizomwe zimachitika nthawi zonse, ndipo zotsatira zowerengera zidzakhala ndi kupatuka kwakukulu. Chifukwa chake, njira yatsopano yowerengera ndiyofunikira kuti muwerengere bwino madulidwe a maginito ndi kutayika kwachitsulo kwa chitsulo chamagetsi pansi pazovuta zamunda, kuti mulingo wogwiritsa ntchito zida zachitsulo ukhale wapamwamba, ndikuwonetsa magwiridwe antchito monga mphamvu ya maginito okhazikika amagetsi amafikira. mlingo wapamwamba.

Zheng Yong ndi ofufuza ena adayang'ana kwambiri kukhudzidwa kwa kupsinjika kwapakati pa magwiridwe antchito a maginito okhazikika, ndikuphatikiza kusanthula koyeserera kuti afufuze njira zoyenera za kupsinjika kwa maginito komanso kutayika kwachitsulo kutayika kwazinthu zokhazikika zamagetsi amagetsi. Kupsyinjika kwachitsulo pakati pa injini yokhazikika ya maginito pansi pazigawo zogwirira ntchito kumakhudzidwa ndi magwero osiyanasiyana a kupsinjika maganizo, ndipo gwero lililonse la kupsinjika maganizo limasonyeza katundu wosiyana kwambiri.

Kuchokera kumaganizo a mawonekedwe a kupsinjika kwa stator pachimake cha maginito okhazikika a maginito, magwero a mapangidwe ake akuphatikizapo nkhonya, riveting, lamination, kusokoneza msonkhano wa casing, etc. malo okhudzidwa kwambiri. Kwa rotor ya motor maginito okhazikika, magwero akulu a kupsinjika komwe amakhala nawo ndi kupsinjika kwamafuta, mphamvu ya centrifugal, mphamvu yamagetsi, ndi zina zambiri. imayikidwanso pakatikati pa rotor.

Chifukwa chake, kupsinjika kwa centrifugal ndiye gwero lalikulu la kupsinjika. Kupanikizika kwapakati pa stator komwe kumapangidwa ndi kusokoneza gulu la maginito okhazikika amagetsi amagetsi kumakhalapo ngati kupsinjika kopanikizika, ndipo gawo lake lochitapo kanthu limakhazikika mu goli la motor stator pachimake, ndikuwongolera kupsinjika kumawonekera ngati circumferential tangential. The kupsinjika katundu wopangidwa ndi mphamvu centrifugal wa okhazikika maginito galimoto rotor ndi kumavuta kupanikizika, amene pafupifupi kwathunthu amachita pa chitsulo pakati pa rotor. The pazipita centrifugal kupsyinjika amachita pa mphambano ya okhazikika maginito galimoto rotor maginito kudzipatula mlatho ndi nthiti kulimbikitsa, kupangitsa kukhala kosavuta kuti ntchito kuwonongeka kuchitika m'dera lino.

Zotsatira za Iron Core Stress pa Magnetic Field of Permanent Magnet Motors

Kuwunika kusintha kwa kachulukidwe ka maginito a magawo ofunikira a maginito okhazikika a maginito, zidapezeka kuti motengera machulukitsidwe, panalibe kusintha kwakukulu kwa kachulukidwe ka maginito pa nthiti zolimbitsa komanso milatho yodzipatula ya maginito ya rotor. Kachulukidwe ka maginito a stator ndi main magnetic circuit amasiyana kwambiri. Izi zitha kufotokozeranso zotsatira za kupsinjika kwapakati pa kugawa kwa maginito kachulukidwe ndi maginito amagetsi agalimoto panthawi yogwiritsa ntchito maginito okhazikika.

Zotsatira za Kupsinjika Maganizo pa Kutaya Kwambiri

Chifukwa cha kupsinjika, kupsinjika kwa goli la maginito okhazikika a motor stator kudzakhala kokhazikika, zomwe zimapangitsa kutayika kwakukulu komanso kuwonongeka kwa magwiridwe antchito. Pali vuto lalikulu lachitsulo chotayika pa goli la maginito okhazikika a galimoto ya stator, makamaka pamphambano ya mano a stator ndi goli, kumene kutaya kwachitsulo kumawonjezera kwambiri chifukwa cha nkhawa. Kafukufuku wapeza kudzera mawerengedwe kuti chitsulo imfa ya okhazikika maginito Motors chawonjezeka ndi 40% -50% chifukwa cha chikoka chakumapeto kupsyinjika, amene akadali odabwitsa ndithu, motero kumabweretsa kuwonjezeka kwambiri imfa okwana maginito okhazikika Motors. Kupyolera mu kusanthula, zitha kupezekanso kuti kutayika kwachitsulo kwa injini ndiyo njira yayikulu yotayika chifukwa cha kukhudzidwa kwa kupsinjika kwapakatikati pakupanga chitsulo chachitsulo cha stator. Kwa rotor ya injini, pamene chitsulo chachitsulo chili pansi pa kupanikizika kwapakati pa centrifugal panthawi yogwira ntchito, sichidzangowonjezera kutaya kwachitsulo, komanso chidzakhala ndi kusintha kwina.

Zotsatira za Kupsinjika pa Inductance ndi Torque

Kugwira ntchito kwa maginito a motor iron core kumasokonekera pansi pa kupsinjika kwapakati pachitsulo, ndipo kutsika kwake kwa shaft kumatsika pang'ono. Makamaka, kusanthula maginito amagetsi amagetsi okhazikika, shaft magnetic circuit imaphatikizapo magawo atatu: mpweya, maginito okhazikika, ndi stator rotor iron core. Pakati pawo, maginito okhazikika ndi gawo lofunika kwambiri. Kutengera pazifukwa izi, magwiridwe antchito a maginito a maginito okhazikika achitsulo chachitsulo akusintha, sizingabweretse kusintha kwakukulu mu inductance ya shaft.

Mbali ya shaft maginito yozungulira yomwe imapangidwa ndi gap ya mpweya ndipo pakatikati pa stator rotor ya injini yamagetsi yokhazikika ndiyocheperako kuposa kukana kwa maginito kwa maginito okhazikika. Poganizira kukhudzidwa kwa kupsinjika kwapakati, magwiridwe antchito a maginito amasokonekera ndipo inductance ya shaft imachepa kwambiri. Yang'anani momwe mphamvu yamaginito imakhudzira pakatikati pachitsulo cha injini yamagetsi yokhazikika. Pamene magwiridwe antchito a maginito a motor core akuchepa, kulumikizana kwa maginito kwa mota kumachepa, ndipo torque yamagetsi yamagetsi okhazikika imachepanso.
