Kwemakore akawanda tichipa ma micro DC motors kuvatengi vemotokari, vezvekurapa, uye vezvemagetsi, takaunganidza mibvunzo inowanzo bvunzwa. Heano mibvunzo mishanu yepamusoro, ine mhinduro dzinoshanda kubva kuchikwata chedu chemainjiniya emufekitori.

Mubvunzo wekutanga: Mota yangu ine ruzha kupfuura zvandaitarisira - chii chingave chisina kumira zvakanaka?

Ruzha runowanzobva kuzvinhu zvemakanika kana zvemagetsi. Zvemakanika: tarisa kana masikuruu ekukwirisa akareba zvakanyanya, zvichikonzera kusangana kwemukati, kana kuti shaft coupling isina kumira zvakanaka. Zvemagetsi: mota dzakakweshwa dzinoburitsa ruzha runopfuta; kuwedzera ceramic capacitor (0.1µF) pamativi ese emagetsi kunogona kudzikisa ruzha rwacho. Kuti urambe uchichema kakawanda, chinja kuenda kuBLDC kana mota isina core.

Q2: Mota inotanga zvisingaite kana kuti inomira kana mutoro wakareruka.

Izvi zvinowanzova kudzikira kwevoltage kana kuti starting torque isina kukwana. Yera voltage pamamota terminals - waya dzakatetepa refu dzinogona kukonzera kudzikira kukuru. Zvakare, ma micro motors anoda starting current yakakwira kupfuura running current. Iva nechokwadi chekuti simba rako rinogona kupa kanenge kaviri rated stall current kwema milliseconds mashoma. Kana dambudziko rikaramba riripo, edza mota ine stall torque yakakwira kana giya rakaderera.

Mubvunzo wechitatu: Ndingadzivirira sei mota kubva kumatambudziko eEMC/EMI?

Mota dzakakweshwa dzinozivikanwa nekuburitsa utsi hunobuda nemwaranzi uye hunobva mumhepo. Kugadzirisa kuri nyore:

Ma capacitor eSolder (kazhinji 0.1µF + 0.01µF) kubva paterminal yega yega kuenda kukesi.

Shandisa waya dzakamonyoroka nesimbi yeferrite pedyo nemota.

Kuti zvinyatsotevedzwa (semuenzaniso, zvekurapa kana zvemotokari), funga nezvemota yeBLDC - kuchinja kwayo kwemagetsi hakunyanyi kukanganisa.

Mubvunzo wechina: Tembiricha yekushanda yakachengeteka ndeipi?

Mazhinji emota dze micro DC anoshandisa class E (120°C) kana class B (130°C). Tembiricha yemhepo pamwe nekudziyisa kwayo zvinofanirwa kugara pasi pemuganhu uyu. Kazhinji, mota haifanirwe kudarika 85°C yemamota akakweshwa, kana 100°C yeBLDC. Tembiricha yepamusoro inoshatisa magineti nemafuta. Kune nzvimbo dzinopisa (semuenzaniso, nzvimbo dzeinjini), kumbira magineti nemafuta anodziya panguva yekupisa.

Mubvunzo 5: Ndingawedzera sei hupenyu hwemota yangu ndichishanda nguva dzose?

Hupenyu hunoganhurirwa nekupfekwa kwebhurashi (mota dzakaputirwa) kana kupfekwa kwebheyaringi (mota dzese). Kuti ugone kushandisa simba rakawanda:

Mhanya nemagetsi akaderera anoenderana nekumhanya/torque yako - kupisa kushoma, brush shoma.

Dzivisa kutenderera kwekutanga/kumisa kakawanda - kutanga kwega kwega kunokonzera brashi current yakakwira.

Chengeta guruva nehunyoro mukati - shandisa nzvimbo yakavharirwa ine IP kana kuisa shaft seal.

Pakushandisa maawa makumi maviri nemana pazuva, chinja kuenda kumota yeBLDC - hupenyu hwebhurashi hahusisiri dambudziko.
