Taw qhia rau Peb -Phase Asynchronous Motors

Peb -theem asynchronous lub cev muaj zog (los yog induction lub cev muaj zog) yog ib hom hluav taws xob lub cev muaj zog los ntawm cov khoom siv ib txhij ntawm 380V peb-theem alternating tam sim no (nrog rau theem sib txawv ntawm 120 degrees). Nws yog hu ua "asynchronous" vim hais tias nws rotor rotates nyob rau hauv tib txoj kev raws li lub stator lub rotating magnetic teb, tsis tau ntawm ib tug sib txawv ceev - ua rau ib tug phenomenon hu ua "slip." Lub rotor ntawm peb -theem asynchronous lub cev muaj zog rotates ntawm qhov ceev qis dua li ntawm rotating magnetic teb; Qhov kev sib txheeb ntawm cov rotor windings thiab cov hlau nplaum sib nqus ua rau lub zog hluav taws xob (EMF) thiab tam sim no nyob rau hauv cov windings, uas tom qab ntawd cuam tshuam nrog cov magnetic teb los tsim hluav taws xob torque, yog li ua kom lub zog hloov dua siab tshiab.

Piv rau ib zaug xwb -theem asynchronous motors, peb-theem asynchronous motors muab kev ua haujlwm zoo tshaj plaws thiab tso cai rau kev txuag hauv ntau yam ntaub ntawv. Raws li cov qauv rotor, peb -theem asynchronous motors raug faib ua ob hom: squirrel- tawb thiab qhov txhab-rotor. Squirrel-cage asynchronous motors muaj cov qauv yooj yim, txhim khu kev qha, lub teeb yuag, thiab tus nqi qis, ua rau lawv daim ntawv thov dav; Txawm li cas los xij, lawv qhov tsis zoo yog qhov nyuaj cuam tshuam nrog kev tswj ceev. Hauv qhov sib piv, lub qhov txhab-rotor peb-theem asynchronous lub cev muaj zog yog nruab nrog peb-theem windings ntawm nws lub rotor{12}}zoo li nws stator- uas txuas nrog rau lwm qhov sib txawv ntawm qhov sib txawv ntawm cov nplhaib thiab txhuam. Los ntawm kev kho qhov tsis kam ntawm qhov hloov pauv no, ib tus tuaj yeem txhim kho lub cev muaj zog pib ua haujlwm thiab tswj nws txoj haujlwm ceev.
