Introduction to the Principple of
NF DC brushless magnetic twj tso kua mis, raws li lub npe qhia, siv lub zog sib nqus los hloov lub zog kinetic hauv lawv cov qauv, thiab lawv tau tsav los ntawm DC brushless motors, li no lub ntsiab lus: DC brushless magnetic twj.
Peb lub twj tso kua mis muaj plaub qhov tseem ceeb: lub taub hau twj tso kua mis, lub tshuab nqus hlau nplaum, DC brushless lub cev muaj zog, thiab tus maub los. Lub magnetic actuator muaj ib tug stator thiab ib tug sib nqus rotor, sib cais los ntawm ib tug nyias phab ntsa, tshem tawm qhov yuav tsum tau rau cov tsoos mechanical ncej ntsaws ruaj ruaj thiab yog li muab ib tug tag nrho kaw system.
Lub cev muaj zog torque yog tsim los ntawm energizing cov coils ntawm silicon steel los xij (stator), tsim ib qho chaw sib nqus uas tsav cov hlau nplaum ruaj khov (rotor). Magnetizing cov hlau nplaum ntawm n (n yog tus lej lej) qib tsim kom muaj qhov sib nqus sib nqus tag nrho. Thaum cov hlau nplaum tsim los ntawm stator coils thiab cov hlau nplaum yog qhov sib txawv (piv txwv li, lub kaum sab xis txav ntawm ob tus ncej yog 0), lub zog sib nqus ntawm lub cev yog qhov qis tshaj. Thaum cov ncej tig mus rau tib tus ncej (piv txwv li, lub kaum sab xis txav ntawm ob tus ncej yog Φ=2π / n), lub zog sib nqus ntawm lub cev yog qhov siab tshaj plaws. Tom qab lub zog sab nraud raug tshem tawm, cov hlau nplaum ntawm cov hlau nplaum sib nqus sib nqus sib nqus, thiab cov hlau nplaum yuav rov qab los rau nws lub zog sib nqus qis tshaj plaws. Qhov no ua rau cov hlau nplaum txav mus, tsav cov hlau nplaum rotor tig.
Lub stator thiab rotor ntawm lub twj tso kua mis sib nqus yog sib cais tag nrho, kom tsis txhob muaj teeb meem ua kua dej tam sim no hauv cov twj tso kua mis DC. IP67 waterproof ntsuam xyuas tsim tau zoo txhim kho lub twj tso kua mis lub neej kev pab cuam thiab kev ua tau zoo.
