1 Gịnị bụ aNEMAmoto stepper?

Moto stepping bụ ụdị moto njikwa dijitalụ, nke a na-ejikarị eme ihe n'ọtụtụ ngwa akpaka.NEMA moto nzọụkwụbụ moto nzọụkwụ nke e mere site na ijikọta uru nke ụdị magnet na-adịgide adịgide na ụdị reactive. Nhazi ya yiri nke moto nzọụkwụ reactive. A na-ekewa rotor ahụ n'ime ngalaba abụọ n'akụkụ axial. A na-ekesa akụkụ abụọ nke isi ígwè ahụ n'otu aka ahụ na otu ọnụọgụ na nha nke obere ezé n'akụkụ gburugburu, mana ọkara nke pitch ezé na-agbagọ ha.

Nhazi nke moto steepụ NEMA yiri nke moto reluctance, nke nwekwara stator na rotor. Stator nkịtị nwere ogidi 8 ma ọ bụ ogidi 4. A na-ekesa ụfọdụ obere ezé n'otu n'otu n'elu ogidi ahụ. Enwere ike inye coil dị na ogidi ahụ ike n'akụkụ abụọ iji mepụta ogidi a na ogidi a, yana ogidi b na ogidi b.

Ezé niile dị n'otu akụkụ nke agụba rotor nwere otu polarity, ebe polarity nke agụba rotor abụọ dị na ngalaba dị iche iche dị iche. Ihe dị iche n'etiti moto steepụ NEMA na moto steepụ reactive bụ na mgbe ihe magnetik na-adịgide adịgide nke magnetized mebiri emebi, a ga-enwe ebe oscillation na mpaghara ndị na-apụ apụ.

 

Uru 3 nkeNEMAmoto nzọụkwụ

Rotor nke moto steepụ NEMA bụ magnetik, yabụ ike ọkụ eletrik nke a na-emepụta n'okpuru otu ọkụ ọkụ stator ahụ karịrị nke moto steepụ reactive, akụkụ steepụ ahụ na-adịkarị obere. N'otu oge ahụ, ka ọnụọgụ nke usoro (ọnụọgụ nke windings ikere ọkụ) na-abawanye, akụkụ steepụ nke moto steepụ NEMA na-ebelata ma na-eme ka izi ezi dịkwuo mma. A na-ejikarị ụdị moto steepụ a eme ihe nke ukwuu.

 

Uru nkeNEMAmoto nzọụkwụ:

1. Mgbe ọnụọgụgụ nke ụzọ abụọ nke ogidi hà nhata na ọnụọgụ nke ezé rotor, enwere ike ịgbanwe mgbanwe ya dịka ọ dị mkpa;

2. Inductance na-agbagharị agbagharị anaghị agbanwe agbanwe ma ọ bụrụ na rotor ahụ dị, nke a na-eme ka ọ dị mfe inweta njikwa ọrụ kacha mma;

3. Mgbe ejiri ihe magnetik ọhụrụ na-adịgide adịgide nwere ngwaahịa ike magnetik dị elu mee ihe na sekit magnetizing axial, arụmọrụ nke moto ahụ nwere ike imeziwanye;

4. Rotor nwere ike inye mkpali maka ígwè magnetik.
