Puas muaj qhov sib txawv ntawm brushless DC thiab brushless DC thaiv? Ob leeg tuaj yeem siv nrog DC ceev regulators?

Kev sib hloov ntawm brushed DC motors yeej ib txwm ua tiav los ntawm kev sib cuag graphite txhuam nrog lub nplhaib commutator ntsia ntawm lub rotor. Lub brushless DC lub cev muaj zog siv Hall sensor los pub rov qab rotor txoj hauj lwm mus rau kev tswj Circuit Court, kom nws thiaj li paub lub caij nyoog ntawm lub cev muaj zog commutation. Feem ntau brushless motor manufacturers tsim motors nrog peb Hall effect positioning sensors. Txij li cov brushless motors tsis muaj txhuam, tsis muaj kev cuam tshuam cuam tshuam, yog li lawv huv dua, tsis muaj suab nrov, thiab qhov tseeb yuav tsum tsis muaj kev saib xyuas, thiab muaj lub neej ntev dua.

Qhov thib ob, brushless DC yog tsim los ntawm lub hauv paus ntsiab lus ntawm AC ceev tswj. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, nws muaj ob qhov loj pib torque ntawm DC motors, ruaj khov ceev thiab yooj yim ceev kev tswj, thiab cov qauv yooj yim ntawm AC motors tsis hnav qhov chaw (tsis muaj carbon txhuam ntawm DC motors)

Peb, nqe. Vim hais tias nws yuav tsum tau ib tug tshwj xeeb tsav Circuit Court tsav, tus nqi yog hais txog 3 mus rau 4 lub sij hawm siab tshaj li ntawm cov zoo tib yam DC motors.

Thib plaub, technical level. Vim hais tias feem ntau brushless DC motors muaj lawv tus kheej tsav circuits (kev tswj ceev yog ua tau, ntawm chav kawm, kuj muaj qhov ceev ceev sawv daws yuav), yog li ntawd yuav tsum tau tsav nws, koj tsuas yog yuav tsum tau txuas nws mus rau lub ntsuas voltage thiab input lub ceev tswj PWM teeb liab. Qhov no tsis tas yuav tsum muaj qhov sib ntxiv ntawm lub zog tsav hluav taws xob. Tsis tas li ntawd, DC brushless lub cev muaj zog muaj Hall lub ntsiab lus rau kev tawm tswv yim, yog li qhov ceev yuav luag ruaj khov thiab tas li.
