Taw qhia rau lub cev muaj zog
Feb 14, 2023| Hluav taws xob lub cev muaj zog yog cov cuab yeej uas hloov hluav taws xob hluav taws xob mus rau hauv lub tshuab hluav taws xob. Nws siv lub zog coil (xws li stator winding) los tsim cov rotating magnetic teb thiab ua rau ntawm lub rotor (xws li squirrel-cage kaw aluminium thav duab) los tsim cov magneto-electrodynamic rotating torque. Cov motors tau muab faib ua DC motors thiab AC motors raws li qhov sib txawv ntawm lub zog siv. Feem ntau ntawm cov motors nyob rau hauv lub hwj chim system yog AC motors, uas yuav ua tau synchronous motors los yog asynchronous motors (qhov ceev ntawm stator magnetic teb ntawm lub cev muaj zog tsis synchronous nrog ceev ntawm lub rotor rotor). Lub cev muaj zog yog tsim los ntawm stator thiab rotor. Cov kev taw qhia ntawm lub zog txav ntawm lub zog hlau nyob rau hauv cov hlau nplaum muaj feem xyuam rau cov kev taw qhia ntawm tam sim no thiab sib nqus induction kab (magnetic field direction). Lub hauv paus ntsiab lus ua haujlwm ntawm lub cev muaj zog yog qhov sib nqus ua haujlwm ntawm lub zog ntawm qhov tam sim no kom lub cev muaj zog tig.
