Lub magnetic chuck yog cov khoom siv kho tshuab uas ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev sib nqus kev sib nqus. Nws feem ntau muaj rotor thiab stator. Lub rotor thiab stator txuas nrog kev sib nqus sib nqus, thiab lub zog tswj tau tso cai rau kev tswj hwm ntawm rotor txoj haujlwm, ceev, thiab raug.
Cov qauv yooj yim ntawm cov hlau nplaum chuck muaj xws li lub rotor, stator, cov lus qhia, thiab cov hlau nplaum. Cov kev taw qhia rails yog tsau rau lub stator, thiab cov hlau nplaum ua los ntawm cov ntaub ntawv xws li ferrite yog muab tso rau ntawm cov lus qhia. Thaum energized, ib tug magnetic teb yog tsim nyob rau hauv lub stator, generating magnetic quab yuam. Cov hlau nplaum nyob rau ntawm lub rotor, thiab cov hlau nplaum ntawm cov hlau nplaum thiab stator nyiam ib leeg, yog li ua tiav cov levitation thiab kev sib hloov ntawm lub rotor.
