PWM (Pulse Width Modulation) ndi njira yomwe imagwiritsidwa ntchito kwambiri powongolera liwiro ndi mphamvu ya kugwedezeka kwa ma DC kapena ma vibration motors. Pamene chizindikiro cha PWM cha pafupipafupi chikugwiritsidwa ntchito pa mota, mphamvu yapakati yomwe imayendetsa mota ndi chizindikiro chimenecho. Izi zimathandiza kuwongolera bwino liwiro la mota ndi mphamvu ya kugwedezeka. Ndi chida chofunikira kwambiri pa ntchito zosiyanasiyana kuphatikizapo maloboti, makina amafakitale, ndi zamagetsi.
Mvetsetsani zoyambira za zizindikiro za PWM
Kuti mugwiritse ntchito PWM polamulira liwiro ndi mphamvu ya kugwedezeka kwa mota, ndikofunikira kumvetsetsa zoyambira za zizindikiro za PWM. Chizindikiro cha PWM chimakhala ndi ma pulse angapo, pomwe m'lifupi mwa pulse (chotchedwa duty cycle) chimazindikira voltage yapakati yomwe imagwiritsidwa ntchito pa mota. Mwa kusintha kayendedwe ka ntchito ya chizindikiro cha PWM, voltage yogwira ntchito ndi mphamvu yoperekedwa ku mota imatha kulamulidwa, potero kusintha liwiro ndi mphamvu ya kugwedezeka kwa mota.
Mukagwiritsa ntchito PWM ku amota yogwedera ya ndalama, kuchuluka kwa chizindikiro cha PWM kumachita gawo lofunika kwambiri pakutsimikiza momwe injini imagwirira ntchito. Ma frequency apamwamba a PWM amalola kuwongolera bwino komanso molondola liwiro la injini ndi mphamvu yogwedezeka. Kuphatikiza apo, ma frequency a PWM ayenera kusankhidwa mosamala kuti apewe zotsatira zoyipa monga phokoso lomveka kapena kugwedezeka kwa makina mu injini.
Chitsanzo cha injini yoyendetsedwa ndi chizindikiro cha PWM
Sankhani chowongolera cha PWM kapena microcontroller yoyenera
Kuti mugwiritse ntchito bwino PWM powongolera liwiro la injini ya kugwedezeka ndi mphamvu ya kugwedezeka, muyenera kusankha wolamulira wa PWM kapena microcontroller woyenera yemwe angapangitse chizindikiro cha PWM chofunikira. Wolamulirayo ayenera kukhala wokhoza kupanga chizindikiro cha PWM chapamwamba chokhala ndi nthawi yosinthika. Kuti chikwaniritse zofunikira za pulogalamuyo.
Kuphatikiza apo, ndikofunikira kuganizira zamota yaying'ono yogwederaMafotokozedwe ndi makhalidwe a ntchito ya injini poika PWM control. Zinthu monga magetsi, mphamvu, makina, ndi magetsi a injini ziyenera kuganiziridwa kuti zitsimikizire kuti ikugwira ntchito bwino komanso motetezeka.
Mayendedwe antchito a PWM
Powombetsa mkota
PWM ndi chida champhamvu chowongolera liwiro ndi mphamvu ya kugwedezeka kwa aInjini ya DC yogwederaMwa kumvetsetsa mfundo za zizindikiro za PWM ndikusankha chowongolera choyenera cha PWM, kuwongolera kolondola komanso kodalirika kwa magwiridwe antchito a mota kumatha kuchitika. Ndi ukadaulo wofunikira kwambiri pakuwongolera ndi kugwedezeka kwa mota.
Funsani Akatswiri Anu Atsogoleri
Timakuthandizani kupewa mavuto kuti mupereke khalidwe labwino komanso kuyamikira zosowa zanu za injini yaing'ono yopanda maburashi, panthawi yake komanso pa bajeti.
