An samun ganyun sauyin da akaun shafin suna buƙatar sararin amfani da kewayon aiki masu damuwa sosai da kewayon zafi mai yawa. Yau da kullun, dukkanin sarayen amfani na mota suna tafi da yawan abubuwan canzawa, amma sarayen tsarin kontin mota yana goyon haske daga cikin waɗannan buƙatutu.

1. Tarihi na Tsarin Kontin Amfanin Motar Ga Ganyun Sauyar Da Akaun Shafin

1.1 Nuna Wurin Lahira

Tsarin kontin amfanin mota wanda ya ke nufi ne tsarin da ke amfani da tsarin duble-loop PID domin hada da juzu'in mota da kewayon rage, don haka yana hada da aikin sararin. Wannan yana iya kiyaye kusurwar motoci da kewayon da aka shigar da su a alamar da aka shigar, sannuwa bisa zuwa kusurwar sake sake da sake rage (DS).

Ganyunan sauyn da akaun shafin (DS) suna canzawa sosai a cikin nau’ikan wasan ganyun sauya. Suna ƙara kama’i na sauya a cikin taccunan uku, suna tarawa ayyukan sauya da sauya kuma suna da mahimmanci a cikin sauya kusan da sauya babban shafin. Mataimakin tsarin kontin amfanin mota shine domin iya kiyaye idogo da kewayon, sauya ganyoyin ganyun sauya, kuma kiyaye kwantar ganyun sauya.

1.2 Matsayin Bincike da Kuskuren Ci Gaba

(1) Matsayin Bincike
A cikin wasan ganyun sauya, an yi amfani da yawan sarayen tsarin kontin amfanin mota saboda tsarin saukin aiki da damuwa sosai, kuma suna da sauƙin amfani. Yan binciken da universityo na duniya dole suka fahimci farkon motar da zarar mota ko zarar mafura, kuma suka nuna saukin tsari, ingancin matsayi, saukin maganar gas mai yawa, da sauƙin aikin dibenshin tsarin da aka fi amfani da shi.

A cikin aiki, sararin ya fara aiki ta hanyar kewayon elektromagnetic da zaune mai kewayon kowane koilu da canje-canjen abin da ke cikin. Amfani da shi a cikin wasan ganyun sauya yana zama kyakkyawan halayyin, kuma manyan mutane na iya samun karuwa—dabbin dabbarorin mota da kuma nuna gyare-gyaren sababbi.

Kodayake wannan tsarin ana amfani da shi a cikin matakan kuɗi, binciken kan amfani da shi a cikin ganyoyin sauyn ba ya gama. Idan mota da abubuwan kontrol suna kasance abin mutumin ganyun sauya na mota, bammuka babu wani tsarin direct-drive da ke amfani da mota don direkta aiki ga sake sake da sake rage—wannan yana kama da iyakokin aikin.

(2) Matsayin Ci Gaba
Na kansu, masu amfurar ganyun sauya suna nan yanzu da saukin tsari da haɗin kayan nau’i da teknolojin sababbi domin iya ƙara kwamfuta na tsarin kontrol.

A China, tare da ci gaban sayarwa na kasar ganyun sauya, adadin masu amfani suna kara sosai, kuma yawan masu amfurar kasa mai yawa suna bayarwa. Sarayen ganyun sauya na ganyun sauya na zamani suna canzawa zuwa sama’yan ganyun sauya mai yawa, ingancin kwamfuta, ingancin kwamfuta, kara kwamfuta, karamar girman siriri, da haɗin modul:

• Sama’yan ganyun sauya da kwamfuta yana daidaita da karin buƙatar kasar ganyun sauya;

• Ingancin kwamfuta yana ƙara kwamfutar kewayon;

• Kayan nau’i mai kyau da teknikin kula da ruwa yana ƙara kyakkyawar tsari kuma kiyaye buƙatar gyara;

• Karamar girman siriri yana daidaita da karin buƙatar yankin tsarin da standard.

2. Tsarin Tsarin Kontin Amfanin Motar Ga Ganyun Sauyar Da Akaun Shafin

2.1 BLDCM Sararin Amfanin

BLDCM ita ce Brushless DC Motor. Ta canza AC zuwa DC kuma ta amfani da inverter don canza shi zuwa AC mai kontrol. Tana da ma'auni na motor na synchronized da driver, BLDCM ita ce abin da aka haɗa da elektron da mekanikal wanda ya kama da kurkurun motor na DC ta canza kommutator na mekanikal zuwa electronic.

Tana da saukin hada da kewayon kuma tana da ingancin motar AC, tana da kommutator mara kuskure, kwamfuta mai yawa, da sauƙin gyara. A cikin amfani na ganyun sauya na ganyun sauya, BLDCM yana da switch na kishiyar kuma yana hada da DS ta hanyar crank arm don sake sake da sake rage—wannan yana kama da kurkurun yanki da saukin tsari.

2.2 Sararin TS

"DS" ta nuna ganyun sauya mai ganyun sauya, wanda ta kara kama'ar sauya. Tana da tsarin sauki da kwamfuta mai yawa, abubuwan DS suna canzawa sosai kuma suna da mahimmanci a cikin shirye-shiryen, amfani da kasuwanci da ayyukan fasaha da fasaha.

A cikin tsarin kontrolin amfanin mota, sararin DS yana amfani da Digital Signal Processor (DSP) kamar mutumin tsarin domin hada da duk dukkanin ayyukan tsarin. Tsarin kuma tana da:

• Kontrolin sake sake da sake rage;

• Zabin wurin mota;

• Zabin kewayon.

Don zabin wurin, tsarin zabin wurin yana ba da irin sigina mai saukin kommutator zuwa tsarin kogon logic. An zaba kewayon ta hanyar encoder wanda ya zaba kewayon rotor, siginar LED ta nuna kewayon rage.

Zabin kewayon na zamanin yana tafi da shunt resistors, wanda ke da kurkuru na yanayi, kuma yana kama da kuskuren takaitaccen takaitaccen. Don haka, sauran ƙarfafawa ba su da sauya sosai bisa kansu da tsarin kontrol, kuma suna iya kara takaitaccen takaitaccen, kuma suna kama da kwantar tsarin.

A cikin tsarin taimakon charge/discharge, yanzu samun BLDCM yana canzawa tasiri na amfanin batiri zuwa capacitor. Ana sanya banki na capacitor sai dai kuma an fara daga kayan ikojin gida, wanda ke taimakawa wajen inganci da kama.

3. Canje-canje na Tsarin Yanki don Tsarin Taimako na Makin Sakawa

3.1 Tsarin Taimakon Sakin Gini/Kunya

Wannan tsari yana taimakawa kan idanin kwana ta abubuwan addinin uku ta hanyar hadura da abubuwan addinin uku kuma amfani da shakaran mai zurfi don takaitaccen addini. Yana kare sabon zafi da rashin addini, yayin da yake kiyaye aiki mai inganci da sauƙi.

Lokacin da aka sakawa switch, capacitor yana kara saƙon kaiwar ma'aji ta hanyar diode lokacin da aka sanya. Lokacin da aka kunya, zai kunna ta hanyar resistor. Doleshe za a amfani da diodes masu karin karbari da saƙonnin da suka fi saƙon tsarin gina. Don kare inductance na parasitic, ana kira mu'amalata da snubber capacitors masu karin karbari da kyau.

3.2 Tsarin Nayon Nemo Makin Sakawa

Wannan tsarin yana neman wurin maganetin rotor ta fahimtar saukake, yayin da yake ba da damar taimakawa kan takaitaccen control na winding stator. Ana riga suna saka sensorin Hall uku a cikin disk na Hall, yayin da magnet na gyare-gyare na gyare-gyare yana bayyane maganetin makinta don karin saukin nemo. Lokacin da ya girma, output na sensorin Hall yana canza, wanda ya bada damar nemo elektronikin nayon rotor.

3.3 Tsarin Nayon Nemo

Ana amfani da optical rotary encoder—wanda ke kama da infrared LED–phototransistor optocouplers da disk na shutter masu cuta—to neman nayon girman rotor. Optocouplers suna kai tsakanin sararin gwaggo. Disk na shutter, wanda ke tsakanin LEDs da phototransistors, yana kama da widows wanda ke hadura transmission na ruwa lokacin ya girma. Samun signalin pulsed ya bada damar hisabin karfi da nayon girman rotor.

3.4 Tsarin Nayon Nemo

Nemo na shunt-resistor na yauke yana da rashin karfi da kuskuren saukin nemo. Sai kuma, rashin isolation na electric a tsakanin tsarin kuɗi da tsarin taimako yana bada abin da zai iya zamun saƙon girman voltage wadda zai iya danna alamomin electronic.

Don kare wannan, tsarin mai zurfi yana amfani da sensorin Hall-effect na current masu isolation na electric. A lokacin aiki, alternating current a cikin winding na makin sakawa ana nemo shi, kuma amplifier na summing yana aiki kan output na sensor. Bayan tabbatar da matakin, ana samun saƙon current mai sauƙi da isolation.

3.5 Tsarin Taimakon Sanya/Kunna Capacitor

Yanzu samun BLDCM yana canzawa tasiri na amfanin batiri zuwa haɓakkin capacitor, wanda ke kara kama da sauya tsarin taimakon sanya/kunna. Digital signal processor yana buƙatar saƙon capacitor kada kusan kuma yana kulle sanya kawai lokacin da aka dum chi kowane limitin aiki. Wannan tsari yana farko a cikin taimakon kama da samun signal, wanda ke ba da damar taimakawa kan tsarin taimako.

4. Kammalitin

Tsarin taimakon makon sakawa don high-voltage disconnectors wata kadan daga cikin ayyukan kai tsakanin yaduwar girman kuɗi da tabbatarwa ga zaman lafiyar yau. Ta hanyar karkasa da karkashin tsarken disconnetor na yauke, wannan tsari tana da mahimmanci a cikin karainganci, kama, da inganta a cikin tsarin kuɗi.
