Direct Drive Permanent Magnet Motor Features

Ntchito Mfundo ya Permanent Magnet Motor

The okhazikika maginito galimoto amazindikira mphamvu yobereka zochokera zozungulira kasinthasintha maginito mphamvu mphamvu, ndipo utenga NdFeB sintered okhazikika maginito zinthu ndi mkulu maginito mphamvu mlingo ndi mkulu endowment coercivity kukhazikitsa munda maginito, amene ali ndi ntchito yosungirako mphamvu. Galimoto yokhazikika yamagetsi imakhala ndi mawonekedwe osavuta, okhala ndi zigawo zamkati monga pachimake ndi ma windings, zomwe pamodzi zimazindikira kuthandizira pachimake cha stator. Rotor imakhala ndi bulaketi ndi shaft yozungulira, etc. Maginito ake okhazikika amatengera kapangidwe kake kuti ateteze kuwonongeka kwa maginito okhazikika ndi mphamvu ya centrifugal, kuwonongeka kwa chilengedwe ndi zinthu zina zoyipa, ndipo makamaka zimadalira mphamvu yamaginito kuti izindikire mphamvu. kutembenuka panthawi ya ntchito. Pamene kulowetsedwa kwamakono kuchokera ku stator kumadutsa mu injini, mafunde amatha kupanga maginito, kupereka mphamvu ya maginito, ndipo rotor imazungulira. Kuyika chipangizo chofananira cha maginito pa rotor, rotor ikupitirizabe kusinthasintha pansi pa mgwirizano pakati pa mitengo ya maginito, ndipo mphamvu yozungulira sichidzawonjezeka pamene liwiro lozungulira likugwirizanitsidwa ndi liwiro la mitengo ya maginito.

Makhalidwe a maginito okhazikika a maginito oyendetsa galimoto

Kapangidwe kosavuta

Galimoto yokhazikika ya maginito yoyendetsera galimoto imalumikizidwa mwachindunji ndi ng'oma yoyendetsa, kuchotsa chochepetsera ndi kuphatikiza, kufewetsa njira yopatsira, kuzindikira "kuwonda" ndikuwongolera kuyendetsa bwino.

Otetezeka ndi Odalirika

Ubwino wa maginito okhazikika oyendetsa galimoto amawonekera kwambiri pakuthamanga kwapang'onopang'ono, komwe nthawi zambiri kumakhala kotsika kuposa 90 r/mphindi, pafupifupi 7% yokha ya liwiro la mota yamagawo atatu asynchronous motor, magwiridwe antchito otsika amatalikitsa moyo wautumiki. mayendedwe agalimoto. Kutsekemera kwa stator kwa maginito okhazikika pagalimoto kutengera njira ziwiri, kutengera VPI vacuum pressure dipping insulation process, kenako kutengera njira yopangira epoxy resin vacuum potting, yomwe imathandizira kutsekemera kwa stator ndikuchepetsa kulephera.

moyo wautali wautumiki

Poyerekeza ndi ma mota amtundu wa asynchronous, maginito okhazikika oyendetsa maginito amakhala ndi moyo wautali. Pakugwira ntchito kwa maginito okhazikika agalimoto, mphamvu yamaginito imasinthidwa kukhala mphamvu ya kinetic kuyendetsa chonyamulira lamba, ndikutayika kwa zinthu zochepa, kutsika kwamkati, kuchepa mphamvu zopanda pake zomwe zimadyedwa chifukwa cha kutentha, komanso kuchuluka kwa demagnetization kwake kosatha. maginito ndi zosakwana 1% zaka 10 zilizonse. Chifukwa chake, injini yokhazikika yoyendetsa maginito imatayika pang'ono pakugwira ntchito tsiku ndi tsiku komanso moyo wautali wautumiki, womwe ungakhale zaka zopitilira 20.

Torque yapamwamba

Galimoto yokhazikika ya maginito yoyendetsa galimoto imatengera mawonekedwe otseguka a ma synchronous vekitala, omwe amakhala ndi magwiridwe antchito anthawi zonse, amatha kuthamanga kwanthawi yayitali mkati mwa liwiro lovotera ndi torque yotulutsa, ndipo nthawi yomweyo imakhala yodzaza nthawi 2.0. torque ndi nthawi 2.2 kuyambira torque. Amisiri amatha kugwiritsa ntchito ntchito yowongolera liwiro kuti azindikire kuyambika kofewa kwa katundu wolemetsa pansi pamikhalidwe yosiyanasiyana yolemetsa kuti apewe kusokonezeka kwa kupanga, ndikusintha komanso kudalirika kolemetsa.

Malingaliro a kampani Anhui Mingteng Permanent-Magnetic Machinery & Electrical Equipment Co., Ltdhttps://www.mingtengmotor.com/low-speed-direct-drive-pmsm/ndi bizinesi yamakono komanso yapamwamba kwambiri yophatikiza kafukufuku wamoto wamagetsi okhazikika ndi chitukuko, kupanga, kugulitsa ndi ntchito. Maginito osunthika okhazikika akampani amayendetsedwa ndi ma frequency converter, omwe amatha kukwaniritsa zofunikira pakunyamula komanso kuthamanga. Chotsani ma gearbox ndi ma buffer m'makina otumizira, kugonjetseratu ma motor plus gear reducer power transmission system ilipo pazovuta zosiyanasiyana, ndikuyenda bwino kwambiri, kuyendetsa bwino kwa torque, kupulumutsa mphamvu, phokoso lotsika, kugwedezeka pang'ono, kutentha pang'ono. , ntchito yotetezeka komanso yodalirika, yotsika mtengo yoyika ndi kukonza, ndi zina zotero, ndiye mtundu wokonda kwambiri wama motors kuti ayendetse zinthu zotsika kwambiri!
