Mfundo yogwirira ntchito ndi zabwino za NEMA stepping motor zitha kumveka pang'ono

1 Kodi aNEMAstepper mota?

Stepping motor ndi mtundu wamagetsi owongolera digito, omwe amagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zodziwikiratu. TheNEMA moterendi makwerero agalimoto opangidwa pophatikiza ubwino wamtundu wa maginito okhazikika ndi mtundu wokhazikika. Mapangidwe ake ndi ofanana ndi a reactive stepping motor. Rotor imagawidwa m'magawo awiri munjira ya axial. Magawo awiri achitsulo chapakati amagawidwa mofanana ndi nambala yofanana ndi kukula kwa mano ang'onoang'ono mozungulira, koma amagwedezeka ndi theka la dzino.

2 Ntchito mfundo yaNEMAmotere

Mapangidwe a NEMA stepping motor ndi ofanana ndi amotor yakusafuna, yomwe ilinso ndi stator ndi rotor. Stator wamba ali ndi mitengo 8 kapena 4 mitengo. Mano ang'onoang'ono angapo amagawidwa mofanana pamtunda. Koyilo yomwe ili pamtengo imatha kupatsidwa mphamvu mbali ziwiri kuti ipange gawo A ndi gawo A, ndi gawo B ndi gawo B.

Mano onse pagawo lomwelo la masamba a rotor ali ndi polarity yofanana, pomwe polarity ya masamba awiri a rotor m'magawo osiyanasiyana amatsutsana. Kusiyana kwakukulu pakati pa NEMA poponda injini ndi yotakataka yopondapo ndikuti pamene maginito okhazikika a maginito achotsedwa, padzakhala malo oscillation ndikutuluka.

 

3 Ubwino waNEMAmotere

Rotor ya NEMA stepping motor ndi maginito, kotero torque yomwe imapangidwa pansi pa stator panopa ndi yayikulu kuposa ya reactive stepping motor, ndipo mbali yake nthawi zambiri imakhala yaying'ono. Nthawi yomweyo, ndi kuchuluka kwa magawo (chiwerengero cha ma windings amphamvu), mbali ya sitepe ya NEMA stepping motor imachepa ndipo kulondola kumatheka. Mtundu woterewu wa masitepe ndi womwe umagwiritsidwa ntchito kwambiri.

 

Ubwino waNEMAmotere:

1. Pamene chiwerengero cha ma poli awiri ndi ofanana ndi chiwerengero cha mano a rotor, kusintha kwake kungasinthidwe monga kufunikira;

2. Inductance yokhotakhota imasintha pang'ono ndi malo ozungulira, zomwe zimapangitsa kuti zikhale zosavuta kukwaniritsa kayendetsedwe kabwino ka ntchito;

3. Pamene zipangizo zatsopano zokhazikika za maginito zokhala ndi mphamvu zamagetsi zamagetsi zimagwiritsidwa ntchito mu axial magnetizing magnetic circuit, ntchito ya galimotoyo imatha kusintha;

4. Rotor ikhoza kupereka chisangalalo kwa chitsulo cha maginito.
