Yuav ua li cas nce lub sij hawm deceleration ntawm brushless lub cev muaj zog maub los?

Muaj ntau hom motors, tab sis lawv cov qauv kev ua haujlwm yog tag nrho raws li cov cai ntawm electromagnetic induction thiab electromagnetic force. Yog li ntawd, lub hauv paus ntsiab lus ntawm lawv cov kev tsim kho yog siv cov khoom sib nqus thiab cov khoom siv hluav taws xob tsim nyog los tsim cov hlau nplaum thiab cov hluav taws xob hluav taws xob uas sib koom ua ke ntawm cov hluav taws xob hluav taws xob, yog li tsim hluav taws xob hluav taws xob thiab ua tiav lub zog hloov dua siab tshiab. Raws li lawv txoj kev pib thiab khiav, lub cev muaj zog tuaj yeem muab faib ua capacitor- pib ib zaug-theem asynchronous motors, capacitor-khiav ib zaug-theem asynchronous motors, capacitor-pib{7}}khiav ib zaug-phase asynchronous{9} asynchronous motors, thiab peb -theem motors.

Raws li cov qauv rotor, lub cev muaj zog tuaj yeem muab faib ua squirrel- tawb induction motors (hom koj siv, yav tas los hu ua squirrel-cage asynchronous motors) thiab qhov txhab-rotor induction motors (yav tas los hu ua qhov txhab-rotor asynchronous motors). Lub tawb squirrel tsuas yog ib lub kauj kaw.

(1) Thaum peb lub-theem asynchronous lub cev muaj zog txuas nrog peb-theem AC fais fab mov (txhua theem sib txawv los ntawm 120 hluav taws xob degrees), peb-theem stator windings tsim peb-theem magnetomotive quab yuam (stator rotating magnetomotive force6}) los ntawm qhov thib peb - flow meter rotating magnetic teb. Qhov no magnetic teb rotates clockwise ntawm synchronous ceev raws lub puab voj voog ntawm lub stator thiab rotor.

(2) Qhov no rotating magnetic teb muaj txheeb ze txiav suab nrog cov rotor conductors. Raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, lub rotor conductors (rotor windings yog kaw Circuit Court) tsim ib tug induced electromotive quab yuam thiab induced tam sim no (kev taw qhia ntawm induced electromotive quab yuam yog txiav txim los ntawm txoj cai- tes txoj cai).

(3) Raws li txoj cai lij choj ntawm electromagnetic quab yuam, nyob rau hauv qhov kev txiav txim ntawm induced electromotive quab yuam, ib tug induced tam sim no yuav raug generated nyob rau hauv lub rotor conductors, nrog rau cov kev taw qhia yog yeej ib yam li cov induced electromotive quab yuam. Cov tam sim no - nqa rotor conductors raug rau lub zog electromagnetic nyob rau hauv magnetic teb generated los ntawm stator (kev taw qhia ntawm lub zog yog txiav txim los ntawm sab laug- tes txoj cai). Lub electromagnetic quab yuam tsim ib qho hluav taws xob torque ntawm lub cev muaj zog rotor ncej, tsav lub cev muaj zog rotor kom tig raws cov kev taw qhia ntawm rotating magnetic teb. Thaum lub cev muaj zog ncej nqa ib tug neeg kho tshuab load, nws outputs mechanical zog. Txij li thaum lub nplhaib sib nqus tsis muaj qhov luv - lub nplhaib hluav taws xob ua rau cov hlau nplaum sib nqus nrog luv luv - lub nplhaib hluav taws xob, cov kev taw qhia ntawm lub cev muaj zog yog tib yam li cov kev taw qhia ntawm cov hlau nplaum rotating.
