PWM (Pulse Width Modulation) ndi njira yomwe imagwiritsidwa ntchito kwambiri kuwongolera kuthamanga ndi kugwedezeka kwamphamvu ya DC kapena ma vibration motors. Pamene chizindikiro cha PWM chapamwamba chikugwiritsidwa ntchito pa injini, mphamvu yamagetsi yomwe imayendetsa galimotoyo ndi chizindikiro chimenecho. Izi zimalola kuwongolera kulondola kwa liwiro la mota ndi mphamvu yakunjenjemera. Ndi chida chofunikira pamagwiritsidwe osiyanasiyana kuphatikiza ma robotics, makina am'mafakitale, ndi zamagetsi zamagetsi.
Kumvetsetsa zoyambira za ma sign a PWM
Kuti mugwiritse ntchito PWM kuwongolera kuthamanga ndi kugwedezeka kwa injini, ndikofunikira kumvetsetsa zoyambira za ma sign a PWM. Chizindikiro cha PWM chimakhala ndi ma pulse angapo, pomwe kutalika kwa pulse (kotchedwa duty cycle) kumatsimikizira kuchuluka kwamagetsi komwe kumagwiritsidwa ntchito pagalimoto. Posintha kayendetsedwe ka ntchito ya siginecha ya PWM, voteji yogwira ntchito komanso yomwe imaperekedwa kugalimoto imatha kuwongoleredwa, potero kusintha liwiro ndi kugwedezeka kwagalimoto.
Mukamagwiritsa ntchito PWM ku acoin vibration motor, mafupipafupi a siginecha ya PWM amakhala ndi gawo lofunikira pakuzindikira momwe injini ikuyendera. Ma frequency apamwamba a PWM amalola kuwongolera bwino, kuwongolera bwino kwa liwiro la mota ndi mphamvu yakugwedezeka. Kuphatikiza apo, ma frequency a PWM amayenera kusankhidwa mosamala kuti apewe zovuta zilizonse monga phokoso lomveka kapena kumveka kwamakina mugalimoto.
Chitsanzo cha injini yoyendetsedwa ndi chizindikiro cha PWM
Sankhani chowongolera cholondola cha PWM kapena microcontroller
Kuti mugwiritse ntchito bwino PWM kuwongolera kuthamanga kwa mota ndi kugwedezeka kwamphamvu, chowongolera choyenera cha PWM kapena microcontroller chiyenera kusankhidwa chomwe chingapangitse chizindikiro cha PWM chofunikira. Woyang'anira akuyenera kupanga chizindikiro cha PWM chokwera kwambiri ndi ntchito yosinthika. Kotero ikhoza kukwaniritsa zofunikira zenizeni za ntchitoyo.
Kuonjezerapo, ndikofunikira kuganizira zainjini yaing'ono yogwedezaMafotokozedwe ndi mawonekedwe ogwiritsira ntchito pokhazikitsa ulamuliro wa PWM. Zinthu monga ma voliyumu, zamakono, zamakina, ndi mawonekedwe amagetsi agalimoto ziyenera kuganiziridwa kuti zitsimikizire kuti zikuyenda bwino komanso moyenera.
Mtengo wapatali wa magawo PWM
Powombetsa mkota
PWM ndi chida champhamvu chowongolera kuthamanga ndi kugwedezeka kwa aDC vibration motor. Pomvetsetsa mfundo za ma sign a PWM ndikusankha chowongolera choyenera cha PWM, kuwongolera kolondola komanso kodalirika kwa magwiridwe antchito agalimoto kumatha kukwaniritsidwa. Ndi ukadaulo wofunikira pakuwongolera magalimoto ndi kugwiritsa ntchito vibration.
Funsani Akatswiri Atsogolereni Anu
Timakuthandizani kupewa misampha kuti mupereke mtunduwo ndikuyamikira chosowa chanu cha micro brushless motor, panthawi yake komanso pa bajeti.
