Lub luag haujlwm ntawm Hall Sensor Rau Brushless DC Tsav

Brushless DC motors ua haujlwm zoo ib yam li cov motors brushed. Brushless motors siv hluav taws xob commutation ntawm winding currents, thaum brushed DC motors siv txhua yam txhuam thiab commutators commute winding tam sim no. Niaj hnub no, peb yuav qhia koj txog lub luag haujlwm ntawm Hall sensors hauv brushless DC motors

DC motors tsim torque hauv DC motors los ntawm kev sib cuam tshuam ntawm cov hlau nplaum ruaj khov magnetic teb thiab tam sim no ntws los ntawm windings. Nyob rau hauv brushless DC motors, Hall txoj hauj lwm sensor pom txoj hauj lwm ntawm lub rotor lub rotating magnetic teb thiab, los ntawm logic thiab tsav circuitry, muab excitation rau sib xws winding. Hall plays lub luag hauj lwm nyob rau hauv sensing cov magnetic ncej rau tus maub los zoo li cas pub cov windings. Peb Hall sib raug mus rau peb-theem winding, kuj tseem muaj ib qho winding ib leeg Hall, thiab ob chav Hall ob chav winding ob chav Hall, lub hom phiaj yog los hloov lub luag hauj lwm ntawm mechanical commutator. Nyob rau hauv dav dav, lub winding reacts raws li lub magnetic teb ntawm lub cev muaj zog hlau nplaum mus tas li los tsim lub torque yuav tsum tau.

Cov saum toj no yog lub luag haujlwm ntawm brushless lub cev muaj zog Hall sensor, cov ntaub ntawv ntau ntxiv txog Vshida micro lub cev muaj zog txais tos sab laj txhua lub sijhawm!
