Isimiso sokusebenza kanye nezinzuzo ze-NEMA stepping motor kungaqondwa ngokushesha

1 Kuyini i-I-NEMAinjini ye-stepper?

I-Stepping motor uhlobo lwemoto yokulawula yedijithali, esetshenziswa kabanzi emishinini ehlukahlukene ezenzakalelayo.I-NEMA injini yokunyathelaiyimoto yokunyathela eklanyelwe ngokuhlanganisa izinzuzo zohlobo lwemagnethi oluhlala njalo kanye nohlobo lwe-reactive. Isakhiwo sayo sifana nesemoto yokunyathela ephendulayo. I-rotor ihlukaniswe izingxenye ezimbili ohlangothini lwe-axial. Izingxenye ezimbili zomgogodla wensimbi zisatshalaliswa ngokulinganayo ngenani elifanayo nosayizi wamazinyo amancane ohlangothini oluzungezile, kodwa zixazululwe yi-half pitch yezinyo.

2 Isimiso sokusebenzaI-NEMAinjini yokunyathela

Isakhiwo se-NEMA stepping motor sifana nese-nustress motor, esakhiwe ne-stator ne-rotor. I-stator evamile inezingodo ezingu-8 noma izingodo ezingu-4. Inani elithile lamazinyo amancane asakazwa ngokulinganayo ebusweni be-pole. I-coil epalini ingafakwa amandla ngezindlela ezimbili ukuze yakhe isigaba a nesigaba a, kanye nesigaba b nesigaba b.

Wonke amazinyo engxenyeni efanayo yama-rotor blades ane-polarity efanayo, kuyilapho i-polarity yama-rotor blades amabili ezingxenyeni ezahlukene iphambene. Umehluko omkhulu phakathi kwe-NEMA stepping motor kanye ne-reactive stepping motor ukuthi lapho izinto ezihlala zisebenza nge-magnetized zisuswa ku-magnetized, kuzoba namaphuzu okunyakaza kanye nezindawo ezingaphandle kwezinyathelo.

 

3 Izinzuzo zeI-NEMAinjini yokunyathela

I-rotor ye-NEMA stepping motor inobuthi, ngakho-ke i-torque ekhiqizwa ngaphansi komshini we-stator ofanayo inkulu kuneye-reactive stepping motor, futhi i-angle yesinyathelo ivame ukuba yincane. Ngesikhathi esifanayo, ngokwanda kwenani lezigaba (inani lama-windings anamandla), i-angle yesinyathelo ye-NEMA stepping motor iyancipha futhi ukunemba kuyathuthuka. Lolu hlobo lwe-stepping motor lusetshenziswa kakhulu.

 

Izinzuzo zeI-NEMAinjini yokunyathela:

1. Uma inani lama-pole pair lilingana nenani lamazinyo e-rotor, ushintsho lwawo lungalungiswa njengoba kudingeka;

2. Ukungena kwe-winding akushintshi kangako ngesimo se-rotor, okwenza kube lula ukufeza ukulawula ukusebenza okuhle kakhulu;

3. Uma kusetshenziswa izinto ezintsha ezihlala njalo ezisebenzisa amandla kazibuthe aphezulu kusekethe kazibuthe ye-axial magnetizing, ukusebenza kwemoto kungathuthukiswa;

4. I-rotor inganikeza ukuvusa insimbi edonsayo.
