A TT MOTOR, jerin TBC4370 suna wakiltar wani dandamali mai ƙarfi na injin DC mara goga wanda aka tsara don aikace-aikace masu buƙatar ci gaba da juyi, kewayon gudu mai faɗi, da tsawon rai na sabis. Tare da nau'ikan ƙarfin lantarki guda biyu na yau da kullun (24V da 48V), wannan injin mai firam 43mm yana isar da ƙarfin juyi har zuwa 2000 g·cm kuma ya wuce ƙarfin fitarwa na 90W. Amma menene ainihin ma'anar waɗannan lambobi ga ƙirar ku?

1. Ƙarfin Wutar Lantarki da Naɗewa Mai Kyau - 24V da 48V

Takardar bayanai tana nuna samfura guda biyu: TBC4370‑2450 (24V) da TBC4370‑4850 (48V). Sigar ƙarfin lantarki mafi girma ba wai kawai maye gurbin faduwa ba ce - tana amfani da juyi daban-daban na juyawa don cimma irin wannan saurin rashin kaya (~5000 rpm). Me yasa ake bayar da duka biyun?

Ana amfani da 24V a cikin motocin lantarki, na'urorin sarrafa masana'antu, da kayan aikin hannu (misali, AGVs, na'urorin kunna wutar lantarki).

48V yana samun karɓuwa a cikin na'urorin EV masu haske, kayan aikin wutar lantarki, da sanyaya uwar garken - yana rage wutar lantarki don irin wannan wutar, yana rage asarar I²R kuma yana ba da damar yin amfani da wayoyi masu siriri.

Zaɓin ƙirar TT MOTOR: Duk nau'ikan biyu suna da kusan ambulan injina iri ɗaya, don haka zaku iya canza ƙarfin lantarki ba tare da canza hanyoyin haɗin injina ba - mai sarrafawa da wayoyi ne kawai ke buƙatar daidaitawa.

2. Babu Lodawa idan aka kwatanta da Saurin da aka ƙayyade - Fahimtar Faɗuwar

Daga samfurin 24V:

Gudun babu kaya ≈ 4950 rpm

Saurin da aka ƙima (a kan ƙarfin juyi mai ƙima) ≈ 4500 rpm

Rage gudu yana kusan kashi 9% ne kawai daga rashin kaya zuwa ƙimar kaya. Wannan yana nuna halayyar ƙarfin juyi mai ƙarfi - alama ce ta kyakkyawan ƙirar BLDC tare da ƙarancin juriya na ciki. Babban raguwa zai nuna juriya mai ƙarfi ko raunin kwararar maganadisu. Ga aikace-aikace kamar na'urorin jigilar kaya ko tsarin fanka, wannan tauri yana nufin saurin da ya dace koda lokacin da kaya ke canzawa.

3. Ƙarfin da Aka Ƙimar - Inda Ainihin Aikin Ke Faruwa

TBC4370‑2450 yana isar da 2000 g·cm (≈0.196 Nm) idan aka kimanta nauyinsa.

Daidai yake da ƙimar 92.3W na takardar bayanai. Wannan shine wurin aiki mai ci gaba - injin zai iya aiki ba tare da iyaka ba a wannan ƙarfin wutar lantarki ba tare da wuce iyakokin zafi ba, muddin zafin ya nutse yadda ya kamata.

Dalilin da yasa 2000 g·cm yake da muhimmanci: Wannan karfin juyi zai iya ɗaga nauyin kilogiram 2 tare da pulley mai tsawon santimita 1, ko kuma ya tuƙa impeller na famfo wanda ke buƙatar matsakaicin matsin lamba. Ya dace da famfunan jiko na likita, ƙananan haɗin hannu na robot, ko sukurorin lantarki.

4. Amfani da Yanzu - Fahimtar Inganci

A lokacin da aka ƙididdige nauyin, samfurin 24V yana ɗaukar 6000 mA (6.0A). Wutar lantarki da aka shigar = 24V × 6.0A = 144W. Ƙarfin injin fitarwa = 92.3W → inganci ≈ 64%.

Ga injin da ba shi da gogewa mai wannan girman (diamita 43mm, tsawon mm 70), kashi 64% a cikakken kaya ya dace, musamman idan aka haɗa da asarar mai sarrafawa. A ƙananan kaya, inganci yakan tashi sama da kashi 75%. Sigar 48V, tare da ƙarfin juyi na g·cm 2000 da kuma wutar lantarki ta mA 2600 (48V × 2.6A = shigarwar 124.8W), tana samun inganci na kashi 74% - mafi kyau saboda ƙarancin asarar jan ƙarfe ya mamaye. Don haka, idan tsarin ku zai iya tallafawa 48V, za ku sami aiki mai sanyi da kuma tsawon lokacin aiki na baturi.

5. Tsarin Tsayawa da Saurin Kuɗi - Abin da ke Faruwa a Start‑Up

Ƙarfin juyi (rotor mai kullewa) na samfurin 24V shine 22,000 g·cm (≈2.16 Nm), kuma ƙarfin juyi shine 80A. Wannan shine ƙarfin juyi sau 11 kuma sama da sau 13 da aka kimanta.

Abubuwan da suka shafi injiniyanci:

Motar na iya karya kayan da suka makale da ƙarfi mai yawa na ɗan lokaci.

Dole ne a kimanta mai sarrafawa don aƙalla ƙarfin wutar lantarki na 80A (ko da na 'yan milliseconds).

Kada a yi aiki a wurin ajiye motoci fiye da daƙiƙa ɗaya - in ba haka ba na'urorin za su yi zafi sosai.

Ga aikace-aikace kamar birkunan ajiye motoci na lantarki ko masu kunna bawul waɗanda ke tsayawa na ɗan lokaci, wannan babban ƙarfin juyi yana da matuƙar amfani.

6. Gine-gine na Inji - Abin da Takardar Bayanai Ba Ta Nuna Ba

Duk da cewa ba a yi cikakken bayani a cikin wannan ɓangaren ba, jerin TBC4370 galibi suna ɗauke da:

Na'urori masu auna sigina na Hall don sauyawa matakai shida (ko kuma ba tare da firikwensin ba zaɓi ne).

Bearings na ƙwallon da aka riga aka ɗora don nauyin radial har zuwa 80N.

Kariyar IP40 (buɗaɗɗen firam), tare da zaɓi na IP54 don mahalli mai ƙura.

Tsarin rotor mai sanda 4 - daidaita ƙarancin coging tare da yawan ƙarfin juyi mai yawa.

An lissafa nauyi a matsayin 520g - ya dace da injin BLDC mai girman 43×70mm, wanda ke nuna lamination na ƙarfe mai ƙarfi da cika jan ƙarfe.
