Ingave diki robhoti mbeva kana diki IoT yemagetsi fan, kuziva kudzora zvinhu neDC mota inemuchina wemidziyoinovhura akawanda ekugadzira DIY mapurojekiti kuti urambe wakabatikana.Muchidzidzo ichi, tiri kushandisa iyola38mota controller pane amuchina wemidziyokusimbisa uye kutenderera peya yeDC mota!
Thela38Mota Controller Module ibhodhi rinobatsira microcontrollers uye microprocessors sengemuchina wemidziyomagetsi DC mota dzinoda kupfuura 3.3V kana 5V.
Inoshandisa iyola38IC yekugonesa zvese zvine musoro uye simba manejimendi inodiwa kutanga mota uye kuparadzanisa iyomuchina wemidziyokubva kumagetsi epamusoro akaiswa kune iyo DC mota.
Thela38module ndiyo hombe mota controller mune yekutanga marobhoti kit nekuti iri nyore kushandisa.Iine misoro yepini kwaunogona kuisa majumper kuti uibatanidze kune yakomuchina wemidziyo.Iwe unogona zvakare kumhanyisa kana kudzikamisa mota nekushandisa pulse-width modulation (PWM) chiratidzo kune yayo pini inogonesa.terminal.
Pane zvecurrents, iyela38ari ahigh current.Chaizvoizvo a10 amp currents inosanganisira mota dzine inakwechinguvana magetsi ekuchinja contact.Izvi zvinokutendera kuti uise iyo yazvino kutungamira pasina kubatanidzazve mota.Kushandura kutungamira kweiyo ikozvino paH-bhiriji inoshandurawo mafambiro ekutenderera kwemota.Iyo la38 ine maviri ekudzora kuonana kwavo, iyo inobvumidza iwe kudzora peya yemotor wakazvimirira.Kana iwe uri mutsva kuPython programming, usapotsa aya anobatsira Python one-liners.
Mune loop yenguva, mapini ekuruboshweKumberi uye ekurudyiMberi anotanga kubatidza kwesekondi imwe.Kuti udzore kumhanya, shandura kutendeuka-kubuda kwebasa kutenderera.Chekutanga uzviise ku100% duty cycle kwesekondi imwe, wozoisa ku50%.Basa rekutenderera kwe100% rinomhanyisa mota nekumhanya kwakanyanya, nepo kutenderera kwe50% kunomhanya nehafu yekumhanya.
Chengetedza se "rpi-dcmotor.py" kana chero rimwe zita refaira kana richipera ne ".py" kuwedzera.Mushure mazvo dzima yakomuchina wemidziyo.
CHERECHEDZA.Aya mapini ejumper anobatanidza otomatiki iyo EN pini ku5V, "ichikubvumidza" iwe kudzora iyocurrentkuburikidza neIN pin.Kunyange iwe uchinge uchiri kupa simba kuburikidza nepini iyi, 5V inogona kukonzera mamwe matambudziko kunemuchina wemidziyosezvainofanirwa kushandisa 3.3V pachinzvimbo che5V.Zvakare, kubatanidza mapini aya kunemuchina wemidziyoichakubvumidza iwe kudzora kumhanya kwemamotor gare gare..
Zano: Kuti uzive kuti nhamba yepini iri paurimuchina wemidziyo, ibate kuitira kuti mapini eGPIO ave kurudyi.Aya tumarata tudiki twakagara patireyi nhema.Zvino kana ukatarisa pamusoro pepini yekuruboshwe kubva patireyi iyoyo, ipini 1. Kurudyi kwayo pane pini 2. Pasi pepini 1 pane pini 3, zvichingodaro.
CHERECHEDZA.Mazhinji emagetsi eDC haawanzo kuve newaya dzekutengesa.Unogona kuzvitengesa iwe pachako.Chero geji ichashanda, asi tambo yemhangura yakasungwa inoshanda zvakanyanya.
Unogona kumhanya kodhi nekumhanyisa script pane terminal.Asi zvisati zvaitika, iwe unofanirwa kuwedzera simba kune iyola38module.
Thela38DC Motor Controller Module inogona kubatana kune chero DC magetsi emagetsi chero bedzi voltage isingapfuure 45V.Panyaya yekushandisa, zvingave nyore kushandisa bhatiri re9V uye plug yeDC yakabatana nemagetsi emodule.
Iwe zvakare haufanirwe kunetseka nezve 9V mabhatiri achikuvadza akomuchina wemidziyo.Thela38module inoshandisa yakakosha IC inonzi MOSFET inoita senge yakaderera simba relay, ichiva iyonguva yemagetsichinja chinoparadzanisa mapini ako kubva kune magetsi.
Ndingatumira sei ikozvino kubva papini kugadzira DC mota kutenderera?Ngatitarisei zvakanyanya kuti tinogadzira sei mota kutenderera.
Thela38mota controller module inoshandisa akati wandeinguva yemagetsiswitches kudzora kutenderera kwemota.Unogona kufunga nezvema switch aya senge switch yemadziro, kunze kwekunge vasingashandise zvigunwe zvako kushanda - vanoshandisa 3.3V kubvamuchina wemidziyo.
Uye ndipo pane GPIO.output(, GPIO.HIGH).Iyi iGPIO.output(, GPIO.HIGH).Kuisa pini iyi kuGPIO.HIGH kunoita kuti pini iyi ibudise 3.3V.Izviinomutsa switch, kubvumira ikozvino kuyerera kune injini.Ikozvino inobva yatenderera injini.Kutenderedza mapini aya kuGPIO.LOW kunodzima switch, iyo inocheka simba kumota.
Tinogona kushandura mafambiro ekutenderera kwemota nekuchinja mafambiro ezvino kuburikidza nemota.Ndokusaka tine mapini maviri akaparadzana ekudzora kutenderera kwemota imwe: kumashure uye kumberi.Vanoshandanguva yemagetsimaswichi kumativi ese emagetsi emota, anotungamira simba kumberi kana kumashure.
Zvimwe chetezvo zvinoenda kune speed.Kusiyana nemapini ekumberi uye ekudzosera kumashure, pini inogonesa inodzora huwandu hwesimba rinoyerera kuburikidza nemota chero nguva.
Nekuwedzera magetsi pakubata-kuvhura, switch yavo inovhura zvishoma "yakafara" uye inobvumira yazvino kuyerera kuburikidza nemota.Kuwedzera simba remainjini kunoita kuti dzifambe nekukurumidza.Kuderera kunoita kuti vanonoke.
Pamuchina wemidziyo, tinoshandisa PWM kana Pulse Modulation kudzora kubuda kwemagetsi emapini.Kuwedzera kutenderera kwebasa kunounza iyo yakanyanya voltage padyo ne3.3V, uye ichidzikisira padyo ne0V.
Chokwadi, unogona "dzima” injini neimwe nzira nekuisa injini inogonesa pini ku0V.Funga nezvazvo sechinhu chakaita semota: mapini ekugonesa anopa gasi rinopa simba mota, uye mapini ekumberi nekumashure anofambisa magiya, achiabvumira kuenda mberi kana kumashure.
Ivo vanosiyana zvichienderana nekuti solenoid coils yavo iri kupi.Iyo DC brushed mota ine coil pakati inotenderera pakati pemhete yemagineti asingagumi.Brushless DC mota dzine makoiri kune rimwe divi - macoil awo emagetsi anotenderedza magineti echigarire.
Mota dzekuunganidzira dzakachipa uye dzine kuita kwakanaka nekumhanya kwakaderera.Nekudaro, ivo vanowanzopisa nekukurumidza kupfuura mabhurashi mota uye haashande nesimba.Nekune rimwe divi, mota dzisina mabhurashi dzinogona kusvika pakumhanya zvakanyanya, kupisa zvishoma, uye kushandisa simba shoma kutenderera nekukurumidza kupfuura mota dzakabhurwa.
Kana uri kushandisa mota mukati amuchina wemidziyorobhoti vhiri giya bhokisi, mota yakabhurwa inofanira kunge iri nani.Nekudaro, kana iwe uri kushandisa isina-giya mota senge diki feni yemagetsi, mota isina brashi inofanira kunge iri nani.
Kunyangwe izvi zvingasiyana nemugadziri, unogona kutarisira 2A peak ikozvino pamota munela38mota mutyairi module.
Terence anofarira marobhoti ari kuyedza kuvaka iro rakanakisa robhoti munyika.Dai asina kunge achipisa maLED sechinhu chechipiri chekuzvivaraidza, angadai akatora izvi kare kare.
