Isimiso sokusebenza kanye nezinzuzo ze-NEMA stepping motor singaqondwa shazi

1 Yini i-aI-NEMAi-stepper motor?

I-stepping motor iwuhlobo lwe-digital control motor, esetshenziswa kabanzi kumishini ehlukahlukene ezenzakalelayo. II-NEMA ukunyathela motoriyinjini yokunyathela eklanywe ngokuhlanganisa izinzuzo zohlobo lukazibuthe oluhlala njalo kanye nohlobo olusebenzayo. Isakhiwo sayo siyefana nesenjini yokunyathela esebenzayo. I-rotor ihlukaniswe yaba izingxenye ezimbili ohlangothini lwe-axial. Izingxenye ezimbili ze-iron core zisakazwa ngokulinganayo ngenani elifanayo nosayizi wamazinyo amancane ohlangothini oluyindilinga, kodwa zinyakaziswa ngesigamu sokuphakama kwamazinyo.

2 Umgomo wokusebenza weI-NEMAukunyathela motor

Isakhiwo se-NEMA stepping motor siyefana naleso semoto engabaza, equkethe ne-stator ne-rotor. I-stator evamile inezigxobo ezingu-8 noma izigxobo ezi-4. Inombolo ethile yamazinyo amancane asatshalaliswa ngokulinganayo endaweni yesigxobo. Ikhoyili esigxotsheni inganikwa amandla ngezindlela ezimbili ukwenza isigaba A nesigaba A, nesigaba B kanye nesigaba B.

Wonke amazinyo esigabeni esifanayo sama-rotor blades ane-polarity efanayo, kuyilapho i-polarity yama-rotor blades amabili ezingxenyeni ezihlukene iphambene. Umehluko omkhulu kakhulu phakathi kwe-NEMA stepping motor kanye ne-reactive stepping motor ukuthi lapho izinto ezisebenza kazibuthe ezihlala unomphela zikhishwa uzibuthe, kuzoba namaphoyinti oku-oscillation kanye nokuphuma kwezinyathelo.

 

3 Izinzuzo zeI-NEMAukunyathela motor

Irotha ye-NEMA stepping motor inguzibuthe, ngakho-ke i-torque ekhiqizwa ngaphansi kwe-stator yamanje nkulu kunaleyo yenjini yokunyathela esebenzayo, futhi i-engeli yesinyathelo ivamise ukuba yincane. Ngesikhathi esifanayo, ngokwanda kwenani lezigaba (inani lamawindi anamandla), i-angle yesinyathelo se-NEMA stepping motor iyancipha futhi ukunemba kuyathuthukiswa. Lolu hlobo lwenjini yokunyathela lusetshenziswa kabanzi.

 

Izinzuzo zeI-NEMAisitebhisi motor:

1. Uma inani lama-pole pair lilingana nenani lamazinyo e-rotor, ukuguqulwa kwalo kungalungiswa njengoba kudingekile;

2. I-inductance ephendukayo ishintsha kancane ngokuma kwe-rotor, okwenza kube lula ukufeza ukulawula ukusebenza kahle;

3. Lapho izinto ezintsha ezihlala njalo kazibuthe ezinomkhiqizo wamandla kazibuthe aphezulu zisetshenziswa kumjikelezo kazibuthe we-axial, ukusebenza kwemoto kungathuthukiswa;

4. I-rotor inganikeza injabulo yensimbi kazibuthe.
