Chifukwa chomwe maginito okhazikika amatha kupulumutsa mphamvu ndi chifukwa chake!

Pamene magawo atatu a stator windings a okhazikika maginito galimoto (aliyense ndi kusiyana 120 ° mu ngodya magetsi) amadyetsedwa ndi magawo atatu alternating panopa ndi pafupipafupi f, ndi kasinthasintha maginito kuti amayenda pa liwiro synchronous adzakhala. kupangidwa.

Pamalo okhazikika, gawo lalikulu la maginito limazungulira molumikizana ndi maginito ozungulira, motero liwiro la rotor limakhalanso liwiro lolumikizana, maginito ozungulira maginito ndi gawo lalikulu la maginito lomwe limakhazikitsidwa ndi maginito okhazikika amakhalabe osasunthika, imalumikizana ndikupanga torque yamagetsi, Galimoto yoyendetsa imazungulira ndikupanga kutembenuka kwamphamvu.

Makina okhazikika a maginito osinthika pafupipafupi amatengera maginito okhazikika amagetsi + inverter (PM motor).The screw host ndi maginito okhazikika okhazikikamota imagawana shaft yayikulu yomweyo.Galimoto ilibe mphamvu., mphamvu yotumizira ndi 100%.Kapangidwe kameneka kamachotsa malo olephereka amtundu wa mota ndikuzindikira kusakonza kwagalimoto.

Maginito osowa padziko lapansi ali ndi maginito abwino kwambiri.Pambuyo magnetization, akhoza kukhazikitsa amphamvu okhazikika maginito munda popanda mphamvu yakunja, amene ntchito m'malo magetsi mathamangitsidwe munda wa Motors chikhalidwe.., Ntchito yodalirika, kukula kochepa ndi kulemera kochepa.Sizingangokwaniritsa magwiridwe antchito apamwamba (monga kuchita bwino kwambiri, kuthamanga kwambiri, kuthamanga kwambiri) kosayerekezeka ndi ma mota achikhalidwe othamangitsa magetsi, komanso amatha kupangidwa kukhala ma mota apadera omwe amatha kukwaniritsa zofunikira zinazake., monga ma elevator traction motors, mota zamagalimoto, etc.

Kuphatikizika kwa maginito osowa kwambiri padziko lapansi omwe ali ndi ukadaulo wamagetsi amagetsi ndi ukadaulo wowongolera ma microcomputer kwathandizira magwiridwe antchito a mota ndi njira yopatsirana pamlingo winanso:

Makina othamanga kwambiri a maginito osinthika nthawi zonse amakhala ndi mphamvu zambiri pansi pa katundu uliwonse, kupulumutsa mphamvu zoposa 38% poyerekeza ndi ma mota wamba komanso kupulumutsa mphamvu kwa 10% kuposa ma motere osintha ma frequency.

Kuchita bwino kwambiri kwa mota kumatha kuyambika injiniyo ikangoyimitsidwa.Ikhoza kuyamba ndi kuyima kosatha popanda kusokoneza moyo wa injini.Zomwe zimayambira sizidutsa 100% ya katundu wathunthu wapano.

Chifukwa maginito okhazikika a ma frequency motor ali ndi maubwino a liwiro lotsika komanso torque yayikulu, mawonekedwe ake owongolera ma frequency ndi otakata kuposa ma induction frequency frequency motor.Makina okhazikika amagetsi amtundu wamagetsi ndi 30% yaying'ono mu voliyumu ndi 35% yopepuka kulemera kuposa ma mota omwe ali ndi mphamvu zomwezo, komanso yosavuta kuyisamalira.Chifukwa chake, kuwongolera magwiridwe antchito ndi mulingo wa zida zothandizira zaukadaulo ndi gawo lofunikira lachitukuko chamakampani opanga magalimoto kuti asinthe momwe mafakitale amagwirira ntchito.

Pakadali pano, injini yamagetsi yamagetsi yokhazikika yokhazikika ndiye chisankho chabwino kwambiri cha screw air compressor drive motor.Ndiwothandiza komanso yopulumutsa mphamvu kuposa wamba magawo atatu asynchronous variable frequency motor!
