Mu polojekitiyi, tikuwonetsani momwe mungapangiremota yogwederadera.
Amota ya vibrator ya dc 3.0vndi mota yomwe imagwedezeka ikapatsidwa mphamvu yokwanira. Ndi mota yomwe imagwedezeka kwenikweni. Ndi yabwino kwambiri pogwedeza zinthu. Ingagwiritsidwe ntchito m'zida zingapo pazifukwa zothandiza kwambiri. Mwachitsanzo, chimodzi mwazinthu zomwe zimagwedezeka kwambiri ndi mafoni am'manja omwe amagwedezeka akayitanidwa akayikidwa mu vibration mode. Foni yam'manja ndi chitsanzo cha chipangizo chamagetsi chomwe chili ndi vibration motor. Chitsanzo china chingakhale rumble pack ya game controller yomwe imagwedezeka, kutsanzira zochita za masewera. Controller imodzi komwe rumble pack ingawonjezedwe ngati chowonjezera ndi nintendo 64, yomwe imabwera ndi rumble packs kuti controller igwedeze kuti itsanzire zochita zamasewera. Chitsanzo chachitatu chingakhale chidole monga furby chomwe chimagwedezeka mukamachita zinthu monga kupukuta kapena kufinya, ndi zina zotero.
Koteromaginito ang'onoang'ono a dc akugwedezekaMa circuit a mota ali ndi ntchito zothandiza komanso zothandiza zomwe zingagwiritsidwe ntchito m'njira zambiri.
Kugwedeza kwa injini yogwedezeka n'kosavuta kwambiri. Chomwe tiyenera kuchita ndikuwonjezera mphamvu yofunikira ku ma terminal awiriwa. Mota yogwedezeka imakhala ndi ma terminal awiri, nthawi zambiri waya wofiira ndi waya wabuluu. Polarity siili yofunika pa ma motors.
Pa mota yathu yogwedera, tidzagwiritsa ntchito mota yogwedera ya Precision Microdrives. Mota iyi ili ndi mphamvu yamagetsi yogwira ntchito ya 2.5-3.8V.
Kotero ngati tilumikiza ma volt atatu kudutsa terminal yake, idzagwedezeka bwino kwambiri, monga momwe zasonyezedwera pansipa:
Izi ndi zokhazo zomwe zimafunika kuti injini yogwedera igwedezeke. Ma volt atatu amatha kuperekedwa ndi mabatire awiri a AA motsatizana.
Komabe, tikufuna kupititsa patsogolo kayendedwe ka injini ya vibration ndikulola kuti iziyang'aniridwa ndi microcontroller mongaarduino.
Mwanjira imeneyi, titha kukhala ndi mphamvu yolamulira mota ya vibration ndipo titha kuyipangitsa kugwedezeka nthawi ndi nthawi ngati tikufuna kapena pokhapokha ngati chochitika china chachitika.
Tidzakusonyezani momwe mungagwirizanitsire injini iyi ndi arduino kuti mupange mtundu uwu wa ulamuliro.
Makamaka, mu polojekitiyi, tidzapanga dera ndikulikonza kutimota yogwedeza ndalama12mm imagwedezeka mphindi iliyonse.
Dongosolo la injini ya vibration lomwe tidzapange likuwonetsedwa pansipa:
Chithunzi cha dongosolo la dera ili ndi:
Mukayendetsa mota pogwiritsa ntchito microcontroller monga arduino yomwe tili nayo pano, ndikofunikira kulumikiza diode reverse biased motsatira mota. Izi ndi zoonanso mukayiyendetsa ndi motor controller kapena transistor. Diode imagwira ntchito ngati chitetezo cha surge ku ma voltage spikes omwe mota ingapange. Ma windings a mota amadziwika kuti amapanga ma voltage spikes akamazungulira. Popanda diode, ma voltage awa amatha kuwononga microcontroller yanu, kapena motor controller IC kapena kutulutsa transistor. Mukangoyendetsa mota ya vibration mwachindunji ndi DC voltage, ndiye kuti palibe diode yofunikira, ndichifukwa chake mu simple circuit yomwe tili nayo pamwambapa, timagwiritsa ntchito gwero la voltage yokha.
Capacitor ya 0.1µF imatenga ma spikes amagetsi omwe amapangidwa pamene maburashi, omwe ndi ma contacts olumikiza magetsi ku ma windings a mota, amatsegulidwa ndi kutsekedwa.
Chifukwa chomwe timagwiritsa ntchito transistor (2N2222) ndichakuti ma microcontroller ambiri ali ndi mphamvu zochepa zotulutsa mphamvu, zomwe zikutanthauza kuti satulutsa mphamvu zokwanira zoyendetsera mitundu yosiyanasiyana ya zida zamagetsi. Kuti tipeze mphamvu zochepa izi, timagwiritsa ntchito transistor kuti tipereke mphamvu zowonjezera mphamvu. Ichi ndi cholinga cha transistor iyi ya 2N2222 yomwe tikugwiritsa ntchito pano. Mota yogwedera imafunika mphamvu yamagetsi pafupifupi 75mA kuti iyendetsedwe. Transistor imalola izi ndipo tikhoza kuyendetsaMota yamtundu wa ndalama ya 3v 1027Kuti tiwonetsetse kuti mphamvu yamagetsi yochuluka kwambiri sikuyenda kuchokera ku transistor yotulutsa, timayika 1KΩ motsatizana ndi maziko a transistor. Izi zimachepetsa mphamvu yamagetsi kufika pamlingo woyenera kotero kuti mphamvu yamagetsi yochuluka kwambiri siikuyendetsa mphamvu yamagetsi.Injini yogwedeza ya 8mm yaying'onoKumbukirani kuti ma transistors nthawi zambiri amapereka mphamvu yowonjezereka nthawi 100 kuposa mphamvu yamagetsi yoyambira yomwe imalowa. Ngati sitiyika resistor pansi kapena pa mphamvu yotulutsa, mphamvu yochuluka kwambiri ikhoza kuwononga mota. Mtengo wa resistor wa 1KΩ si wolondola. Mtengo uliwonse ungagwiritsidwe ntchito mpaka pafupifupi 5KΩ kapena kuposerapo.
Timalumikiza mphamvu yotulutsa yomwe transistor idzayendetsa ku chosonkhanitsira cha transistor. Iyi ndi mota komanso zida zonse zomwe zimafunikira pamodzi nayo kuti ziteteze magetsi amagetsi.
