ʻO ka mea kaulana ʻo Nema 17 pani pani ʻia i ka stepper me nā waihona hou
ʻO nā ʻano haʻalulu mechanical a pau i hana ʻia e ka kaʻa i ka hana e hoʻopau a hoʻopau i ka insulation coil, ʻo ka mea nui loa ʻo ia ka electromagnetic vibration, e pili ana i ka insulation o ka wili hope a me ka notch.Inā ʻaʻole maikaʻi ka maikaʻi o ke kaomi ʻana o ke kumu stator, a ʻaʻole maikaʻi ke kaʻina hana hoʻopaʻa ʻana i ka hopena, e paheʻe ka coil i loko o ka slot, a e neʻe aku ka pahu interlayer a me ke ana ʻana o ke ana wela ma waena o nā coils luna a me lalo. , ka mea e hoʻohana i nā wili luna a me lalo a hōʻino i ka insulation coil.ʻO ka mea hou aku, inā e holo ana ka wili, e hoʻohua ka mea e hele ana i kēia manawa i ʻelua mau manawa o ka ikaika haʻalulu electromagnetic, ʻaʻole ia e hoʻoneʻe wale i ka coil me ka poloka spacing ma ka hope o ka hao a me ka wili, akā ke kumu. ʻO ka haʻalulu ma waena o ka uea a me ka insulation, ma waena o nā huli a me nā kaula o ka uea, ka hopena i ka huli ʻana o ka wili a me nā kaula, pōkole pōkole, wehe a me nā pilikia ʻē aʻe.I ka manawa like, loaʻa nā poho hou ma ka ʻāpana pōkole, kahi e piʻi nui ai ka mahana kūloko o ka wili, hoʻemi ka ikaika insulation, a loaʻa ka hewa insulation breakdown.No laila, ʻo ka vibration electromagnetic ke kumu nui o ka pōʻino insulation coil.
ʻO ka hoʻohui ʻana o nā mea insulation, laminated cores, coil wires a me nā ʻāpana ʻē aʻe i hoʻohana ʻia i ka kaʻa e hana i kona rigidity structural a me nā kūlana o ka hoʻonui ʻana o ka wela a me ke anuanu i ka wā o ka hana, ʻo ia kekahi o nā kumu o ka haʻalulu kaʻa.ʻO ke kaulike ʻole o ka rotor, ka ikaika electromagnetic i loko o ke kaʻa, ka hopena torsional o ke kaʻa ma hope o ka huki ʻana i ka ukana, a me ka hopena o ka mana mana e alakaʻi i ka haʻalulu o ke kaʻa.
ʻO ka haʻalulu o ke kaʻa he mea pōʻino, no ka laʻana, e kūlou a uhaʻi i ka rotor o ke kaʻa;E hoʻokuʻu i ka pou mākia o ka rotor kaʻa kaʻa, e hopena i ka hoʻoheheʻe ʻana i ka stator kaʻa a me ka rotor a me ka hāʻule ʻole ʻana;I kekahi manawa, e hoʻolōʻihi i ka ʻaʻahu o nā bearings a hoʻopōkole loa i ke ola maʻamau o nā bearings;Hoʻokuʻu ʻia nā hopena wili kaʻa, ka hopena i ka hakakā ma waena o nā wili hope, ka hoʻemi ʻana i ke kūʻē ʻana o ka insulation, ka pōkole o ke ola insulation, a me ka haki ʻana i ka insulation i nā hihia koʻikoʻi.
ʻO nā ʻāpana nui e pili ana i ka vibration kaʻa kaʻa kaʻa kaʻa stator core, stator winding, base motor, rotor a me ka bearing.ʻO ka haʻalulu o ka stator core ka mea nui e ka mana electromagnetic, ka mea e hana ai i nā ʻano elliptical, triangular, quadrilateral a me nā ʻano vibration ʻē aʻe.I ka wā e hele ai kahi māla magnetic ma waena o ka stator laminated core, e hana ia i ka haʻalulu axial.Inā ʻaʻole paʻa paʻa ke kumu, e hoʻopuka ke kumu i ka haʻalulu ikaika, a hiki paha i ka haki ʻana o nā niho.I mea e pale aku ai i kēia ʻano haʻalulu, hoʻohana maʻamau ka stator core i ka pā paʻi a me ka hoʻoheheʻe ʻia ʻana o ka ʻōnaehana, akā i ka manawa like, pono e uku ʻia e pale i ka pōʻino i hana ʻia e ka nui o ke kaomi kūloko o ke kumu.
I ka wā o ka hana ʻana o ka kaʻa, hoʻopili pinepine ʻia ka stator winding e ka ikaika hana o ka manawa a me ka leakage flux i ka wili, ka huki magnetic o ka rotor, ka hoʻonui ʻana o ka wela a me ka ikaika contraction o ka wili, a me nā mea ʻē aʻe. ʻōnaehana alapine a i ʻole ʻelua alapine vibration o ka wili.I ka hoʻolālā ʻana i kahi kaʻa, ʻoi aku ka maikaʻi o ka noʻonoʻo ʻana i ka haʻalulu o ka slot a me ka piko o ka wili stator i hoʻokumu ʻia e ka mana electromagnetic.I mea e pale aku ai i kēia mau ʻano haʻalulu ʻelua, pono pinepine e hana i nā ʻano e like me ka hoʻopaʻa ʻana o ka pahu groove a me ka axial rigid bracket ma ka hopena.
