Mfundo yogwirira ntchito ndi ubwino wa NEMA stepping motor zitha kumveka mwachidule

1 Kodi aNEMAmota ya stepper?

Injini yoponda ndi mtundu wa injini yowongolera digito, yomwe imagwiritsidwa ntchito kwambiri mu zida zosiyanasiyana zodziyimira payokha.NEMA mota yopondapondi mota yoyendera yopangidwa mwa kuphatikiza ubwino wa mtundu wa maginito wokhazikika ndi mtundu wa reactive. Kapangidwe kake ndi kofanana ndi ka mota yoyendera yoyendera. Rotor imagawidwa m'magawo awiri mbali imodzi. Magawo awiri a chitsulo chapakati amagawidwa mofanana ndi kuchuluka ndi kukula kwa mano ang'onoang'ono mbali inayo, koma amazunguliridwa ndi theka la dzino.

2 Mfundo yogwirira ntchito yaNEMAmota yopondapo

Kapangidwe ka NEMA stepping motor ndi kofanana ndi ka gaulu la gaulu, lomwe limapangidwanso ndi stator ndi rotor. Stator wamba ali ndi ndodo 8 kapena ndodo 4. Mano ang'onoang'ono angapo amagawidwa mofanana pamwamba pa ndodo. Chozungulira pa ndodocho chikhoza kupatsidwa mphamvu mbali ziwiri kuti apange gawo a ndi gawo a, ndi gawo b ndi gawo b.

Mano onse omwe ali pagawo lomwelo la masamba a rotor ali ndi polarity yofanana, pomwe polarity ya masamba awiri a rotor m'magawo osiyanasiyana ndi yosiyana. Kusiyana kwakukulu pakati pa NEMA stepping motor ndi reactive stepping motor ndikuti pamene maginito okhazikika a maginito achotsedwa mphamvu, padzakhala malo osinthasintha komanso malo opita kunja kwa sitepe.

 

3 Ubwino waNEMAmota yopondapo

Rotor ya NEMA stepping motor ndi ya maginito, kotero mphamvu yopangidwa pansi pa stator current yomweyi ndi yayikulu kuposa ya reactive stepping motor, ndipo ngodya ya sitepe nthawi zambiri imakhala yaying'ono. Nthawi yomweyo, ndi kuchuluka kwa magawo (chiwerengero cha ma windings olimbikitsidwa), ngodya ya sitepe ya NEMA stepping motor imachepa ndipo kulondola kumawonjezeka. Mtundu uwu wa stepping motor umagwiritsidwa ntchito kwambiri.

 

Ubwino waNEMAmota yopondapo:

1. Ngati chiwerengero cha ma pole pairs chili chofanana ndi chiwerengero cha mano ozungulira, kusintha kwake kungasinthidwe ngati pakufunika;

2. Kuzungulira kwa inductance kumasintha pang'ono ndi malo a rotor, zomwe zimapangitsa kuti zikhale zosavuta kukwaniritsa kuwongolera bwino ntchito;

3. Pamene zipangizo zatsopano zamaginito zokhazikika zokhala ndi mphamvu zambiri zamaginito zikugwiritsidwa ntchito mu dera la maginito la axial magnetizing, magwiridwe antchito a mota amatha kukonzedwa;

4. Rotor ikhoza kupereka chisangalalo cha chitsulo cha maginito.
