nkhani

Ku TT MOTOR, mndandanda wa TBC4370 ukuyimira nsanja ya mota ya DC yopanda maburashi amphamvu kwambiri yopangidwira ntchito zomwe zimafuna mphamvu yopitilira, liwiro lalikulu, komanso moyo wautali wautumiki. Ndi mitundu iwiri yamagetsi wamba (24V ndi 48V), mota iyi ya 43mm‑frame imapereka mphamvu yofikira 2000 g·cm ndipo imaposa mphamvu yotulutsa ya 90W. Koma manambala awa amatanthauza chiyani kwenikweni pa kapangidwe kanu?

1. Voltage ndi Windings Zovomerezeka - 24V poyerekeza ndi 48V

Tsamba la deta likuwonetsa mitundu iwiri: TBC4370‑2450 (24V) ndi TBC4370‑4850 (48V). Mtundu wamagetsi wapamwamba siwongosintha malo - umagwiritsa ntchito ma curve osiyanasiyana kuti ukwaniritse liwiro lofanana lopanda katundu (~5000 rpm). N’chifukwa chiyani umapereka zonse ziwiri?

24V imapezeka kwambiri m'magalimoto, zowongolera zamafakitale, ndi zida zoyendera (monga ma AGV, ma actuator amagetsi).

48V ikupeza mphamvu mu ma EV amagetsi, zida zamagetsi, ndi kuziziritsa kwa seva - imachepetsa mphamvu yamagetsi yamagetsi omwewo, kuchepetsa kutayika kwa I²R ndikulola mawaya kukhala ochepa.

Kusankha kapangidwe ka TT MOTOR: Mabaibulo onsewa amakhala ndi ma envelopu ofanana kwambiri a makina, kotero mutha kusintha ma voltage popanda kusintha mawonekedwe a makina - chowongolera ndi mawaya okha ndi omwe amafunika kusinthidwa.

2. Liwiro Losanyamula Katundu Poyerekeza ndi Liwiro Loyesedwa - Kumvetsetsa Kutsika

Kuchokera ku chitsanzo cha 24V:

Liwiro losanyamula katundu ≈ 4950 rpm

Liwiro loyesedwa (pa torque yoyesedwa) ≈ 4500 rpm

Kutsika kwa liwiro ndi pafupifupi 9% yokha kuyambira pa katundu wopanda katundu mpaka katundu wovomerezeka. Izi zikusonyeza kuti mphamvu ya torque ndi yolimba - chizindikiro cha kapangidwe kabwino ka BLDC kokhala ndi kukana kochepa kwamkati. Kutsika kwakukulu kungasonyeze kukana kwakukulu kwa armature kapena kufooka kwa maginito. Pa ntchito monga ma conveyor drive kapena ma fan system, kuuma kumeneku kumatanthauza kuthamanga kokhazikika ngakhale katundu akasintha.

3. Mphamvu ndi Mphamvu Zoyesedwa - Kumene Ntchito Yeniyeni Imachitika

TBC4370‑2450 imapereka 2000 g·cm (≈0.196 Nm) pa katundu wovomerezeka.

Ikugwirizana ndendende ndi 92.3W ya datasheet. Iyi ndi nthawi yogwirira ntchito mosalekeza - mota imatha kugwira ntchito kosatha pa torque iyi popanda kupitirira malire a kutentha, bola ngati kutentha kumatsika bwino.

Chifukwa chiyani 2000 g·cm ndi yofunika: Mphamvu iyi imatha kunyamula kulemera kwa 2 kg ndi pulley ya 1 cm, kapena kuyendetsa pampu yofuna kupanikizika pang'ono. Ndi yoyenera pa mapampu olowetsera mankhwala, malo olumikizirana ang'onoang'ono a robot, kapena ma screwdriver amagetsi.

4. Kugwiritsa Ntchito Pakali pano - Kuzindikira Kugwiritsa Ntchito Bwino

Pakayikidwa mphamvu, chitsanzo cha 24V chimakoka 6000 mA (6.0A). Mphamvu yamagetsi yolowera = 24V × 6.0A = 144W. Mphamvu yamakina yotuluka = ​​92.3W → magwiridwe antchito ≈ 64%.

Kwa mota yopanda burashi ya kukula kotere (m'mimba mwake wa 43mm, kutalika kwa 70mm), 64% mukadzaza mokwanira ndikwabwino, makamaka pophatikiza kutayika kwa chowongolera. Pakulemera kochepa, kugwira ntchito bwino nthawi zambiri kumakwera kuposa 75%. Mtundu wa 48V, wokhala ndi torque ya 2000 g·cm ndi 2600 mA current (48V × 2.6A = 124.8W input), umakwaniritsa kugwira ntchito bwino kwa 74% - bwino chifukwa kutayika kochepa kwa mkuwa kumalamulira. Chifukwa chake, ngati makina anu akhoza kuthandizira 48V, mudzakhala ndi ntchito yozizira komanso nthawi yayitali yogwiritsira ntchito batri.

5. Torque & Current ya Stall - Zomwe Zimachitika Poyambitsa

Mphamvu ya stall torque (yotsekeka) ya mtundu wa 24V ndi 22,000 g·cm (≈2.16 Nm), ndipo mphamvu ya stall current ndi 80A. Ndi mphamvu ya stall torque yochulukira ka 11 ndipo mphamvu ya stall current yochulukira ka 13.

Zotsatira za uinjiniya:

Injiniyo imatha kuchotsa katundu womangika ndi mphamvu yayikulu kwakanthawi.

Wolamulira ayenera kuyesedwa kuti azitha kufika pamlingo wa 80A peak current (ngakhale kwa ma milliseconds ochepa).

Musagwiritse ntchito pamalo osungiramo zinthu kwa nthawi yoposa sekondi imodzi - apo ayi ma windings adzatentha kwambiri.

Pa ntchito monga mabuleki oimika magalimoto amagetsi kapena ma valve actuator omwe amangoima kwa kanthawi kochepa, mphamvu yayikulu iyi ndi yofunika kwambiri.

6. Kupanga Makina - Zimene Datasheet Sizikuwonetsa

Ngakhale kuti palibe tsatanetsatane mu gawo ili, mndandanda wa TBC4370 nthawi zambiri umakhala ndi:

Masensa a Hall a kusintha kwa masitepe asanu ndi limodzi (kapena opanda masensa ngati mukufuna).

Ma bearing a mpira omwe adayikidwa kale kuti azitha kunyamula ma radial load mpaka 80N.

Chitetezo cha IP40 (chimango chotseguka), chokhala ndi IP54 yosankha pa malo okhala ndi fumbi.

Kapangidwe ka rotor ya 4-pole - kulumikiza cogging yochepa ndi torque yambiri.

Kulemera kwalembedwa ngati 520g - koyenera mota ya BLDC ya 43×70mm, kusonyeza kulimba kwachitsulo ndi kudzazidwa kwa mkuwa.
