Izimoto Ze-Access Control Turnstile: I-Brushed vs. i-Brushless vs. i-Servo Motors

Kwadalwa ngo 03.13
Ezinhlelweni zokulawula ukungena nge-turnstile, ukukhetha uhlobo lwemoto kuthinta kakhulu ukusebenza, impilo ende, kanye nezindleko zokugcinwa. Ngezansi kunokufaniswa okunemininingwane kwezinhlobo ezintathu zemoto: i-Brushed DC Motor (BDC), i-Brushless DC Motor (BLDC), kanye ne-Servo Motor.

1. i-Brushed DC Motor (BDC)

Indlela Yokusebenza

  • Isebenzisa amabhulashi kanye ne-commutator ukushintsha isiqondiso samanje, okudala ukujikeleza kwe-rotor.

Izici Eziyinhloko

  • Izinzuzo
    • Izindleko eziphansi
, isakhiwo esilula, ukulawula okulula (kusebenza ngqo ku-DC power).
(cishe amahora angu-1,000–3,000) ngenxa yokuguga kwe-brush/commutator.
(60–75%) – ukulahleka kwamandla ngenxa yokungqubuzana nokushisa.
– kudinga ukushintshwa kwe-brush ngezikhathi ezithile nokuhlanza.
ngenxa yokuthintana komshini.

Izicelo Ezijwayelekile

  • Ama-turnstile ebujetini anezidingo zokuqina okuphansi (ancishiswa kancane yi-BLDC).

2. i-Brushless DC Motor (BLDC)

Indlela Yokusebenza

  • Isebenzisa ukushintsha ugesi (ama-Hall sensors noma ama-FOC algorithms) esikhundleni samabhulashi.

Izici Eziyinhloko

  • Izinzuzo
    • Impilo ende
(amahora angu-10,000+) – akukho ukuguga komshini.
(85–95%) – ukulahleka kwamandla okuncane kakhulu.
– idinga ukugcotshwa kwe-bearing ngezikhathi ezithile.
– akukho msindo wokuhlikihla ibhulashi.
– kusekela ukulungiswa kwejubane nokuqala/ukuyeka okubushelela (kudinga umshayeli).
  • Okungalungile
    • Izindleko eziphakeme
– kudinga umshayeli ozinikezele (isb., i-3-phase inverter).
– kudinga izinzwa noma ama-algorithms okushintsha.

Izicelo Ezejwayelekile

  • Ama-turnstile esimanje (isb., amasango esitimela, izithiyo zehhovisi) lapho ukusebenza nezindleko kulinganisela khona.

3. I-Servo Motor

Indlela Yokusebenza

  • Uhlelo oluvaliwe olune-encoder feedback yokulungiswa kwesikhundla/isivinini/i-torque ngesikhathi sangempela.

Izici Eziyinhloko

  • Okulungile
    • Ukunemba okuphezulu kakhulu
– (iphutha < ±0.1°).
– kulungele ukusebenza okusheshayo, okuqala/ukuyeka kaningi.
– i-torque esheshayo ifinyelela ku-3x inani elilinganisiwe.
  • Okungalungile
    • Izindleko eziphakeme kakhulu
– idinga imoto + idrayivu + i-encoder.
– kudinga ukulungiswa kwamapharamitha e-PID.

Izicelo Ezijwayelekile

  • Ama-turnstile aphezulu (izikhumulo zezindiza, amasiko) noma izimo ezidinga ukunyakaza okusheshayo, okunembayo.

Kuncane kakhulu
Ukunemba Kokulawula
Phansi (umjikelezo ovulekile)
Phakathi (kungaba umjikelezo ovaliwe)
Kuphezulu kakhulu (umjikelezo ovaliwe)
Okulunge kakhulu
Izinhlelo ezishibhile, ezindala
Ama-turnstile ajwayelekile
Amageti esivinini esikhulu, anembayo kakhulu

Umhlahlandlela wokukhetha

  • Izindleko eziphansi, ukusetshenziswa okuphansi
: I-DC enoburashi (iyayeka ukusetshenziswa).
  • Ama-turnstile ajwayelekile
: I-BLDC (ibhalansi enhle kakhulu phakathi kwezindleko nokusebenza).
  • Isivinini esikhulu, ukunemba okuphezulu
: I-Servo (isibonelo, izindawo ezingama-60+ ngomzuzu).
Ngemisebenzi yangempela, izinto ezifana nohlobo lwe-turnstile (i-tripod, i-flap, njll.), izidingo zesivinini, nokuhlanganiswa kwesistimu kufanele kucatshangelwe.
