Basic qauv ntawm induction lub cev muaj zog:
1. Cov qauv ntawm ib theem asynchronous lub cev muaj zog
Ib-theem asynchronous lub cev muaj zog yog lub cev muaj zog uas tsuas yog xav tau ib-theem AC fais fab mov. Ib-theem asynchronous lub cev muaj zog muaj stator, rotor, bearing, casing, kawg npog, thiab lwm yam. Lub stator muaj ib tug ncej thiab ib tug hlau core nrog windings. Cov tub ntxhais hlau yog ua los ntawm silicon steel los xij punched thiab laminated hauv grooves. Ob txheej ntawm lub ntsiab windings (tseem hu ua khiav windings) thiab auxiliary windings (tseem hu ua pib windings tsim auxiliary windings) spaced 90 ° sib nrug yog embedded rau hauv grooves. Lub ntsiab winding yog txuas nrog AC fais fab mov, thiab cov pab cuam winding txuas nrog rau hauv series mus rau lub centrifugal hloov S los yog pib capacitor, khiav capacitor, thiab lwm yam, thiab ces txuas nrog lub hwj huam mov. Lub rotor yog lub tawb-hom cam khwb cia txhuas rotor. Cov tub ntxhais hlau yog laminated thiab tom qab ntawd aluminium yog cam khwb cia rau hauv lub qhov ntawm cov tub ntxhais hlau. Cov rings kawg kuj tau muab pov tseg ua ke kom luv luv ntawm lub rotor qhia tuav rau hauv hom squirrel-cage.
Ib-theem asynchronous motors tau muab faib ua ib-theem tsis kam-pib asynchronous motors, ib-theem capacitor-pib asynchronous motors, ib-theem capacitor-khiav asynchronous motors thiab ib-theem dual-tus nqi capacitor asynchronous motors.
2.Basic qauv ntawm peb-theem asynchronous lub cev muaj zog
Peb-theem asynchronous lub cev muaj zog feem ntau muaj stator, rotor thiab bearings. Lub stator feem ntau yog tsim los ntawm cov tub ntxhais hlau, peb-theem winding, ncej thiab kawg npog. Cov tub ntxhais stator feem ntau yog xuas nrig ntaus thiab laminated los ntawm 0.35 ~ 0.5 hli tuab silicon steel nplooj ntawv nrog ib txheej insulating ntawm qhov chaw. Muaj qhov sib npaug sib npaug ntawm qhov punched hauv lub voj voog sab hauv ntawm cov tub ntxhais kom embed lub stator windings. Peb-theem winding yog tsim los ntawm peb lub windings nrog tib lub qauv uas muaj qhov sib nrug ntawm 120 ° sib nrug los ntawm ib leeg thiab npaj symmetrically. Txhua kauj ntawm cov windings yog embedded nyob rau hauv txhua qhov ntawm lub stator raws li tej kev cai. Nws muaj nuj nqi yog kom dhau nyob rau hauv peb-theem alternating tam sim no thiab tsim ib tug rotating magnetic teb. Lub hauv paus feem ntau yog ua los ntawm cam khwb cia hlau. Lub hauv paus ntawm loj asynchronous motors feem ntau welded nrog steel daim hlau. Lub hauv paus ntawm micro motors yog ua los ntawm cam khwb cia txhuas. Nws txoj haujlwm yog txhim kho lub stator core thiab pem hauv ntej thiab nram qab kawg npog los txhawb lub rotor, thiab ua lub luag haujlwm hauv kev tiv thaiv thiab cua sov dissipation. Muaj cov cua kub dissipation tav nyob rau sab nraud ntawm lub hauv paus ntawm lub cev muaj zog los ua kom cov cua sov dissipation cheeb tsam. Qhov kawg npog ntawm ob qho kawg ntawm lub hauv paus ntawm lub cev muaj zog tiv thaiv muaj lub qhov cua kom tso cai ncaj qha convection ntawm huab cua sab hauv thiab sab nraud lub cev muaj zog los pab kom muaj cua sov. Qhov kawg npog feem ntau ua lub luag haujlwm ntawm kev kho lub rotor, txhawb nqa thiab tiv thaiv nws. Lub rotor feem ntau yog tsim los ntawm cov tub ntxhais hlau thiab windings.
Lub rotor core yog ua los ntawm cov khoom siv tib yam li stator. Nws yog xuas nrig ntaus thiab laminated los ntawm 0.5 hli tuab silicon steel los xij. Lub voj voog sab nrauv ntawm cov ntawv silicon steel yog xuas nrig nrog cov qhov sib npaug sib npaug rau tso cov rotor windings. Feem ntau, lub voj voog sab hauv ntawm silicon steel ntawv punched tawm ntawm stator core yog siv los xuas nrig ntaus lub rotor core. Feem ntau, lub rotor tub ntxhais ntawm me me asynchronous motors yog ncaj qha nias ntawm lub rotating ncej, thaum lub rotor cores ntawm loj thiab nruab nrab asynchronous motors (rotor txoj kab uas hla yog ntau tshaj 300 ~ 400 hli) yog nias ntawm lub rotating ncej nrog kev pab los ntawm lub rotor cores ntawm me me asynchronous motors. ib tug rotor bracket.
