ʻO ka wehewehe ʻana i nā ʻāpana kaʻa stepper (I)

一、Hoʻopaʻa torque;

Pono ka torque e hoʻohuli i ke kumu hoʻopuka kaʻa ke hoʻoikaika ʻia nā ʻāpana ʻelua o nā wili kaʻa stepper me ka helu DC o kēia manawa. ʻOi aku ka liʻiliʻi o ka torque paʻa ma mua o ka torque holo i nā wikiwiki haʻahaʻa (ma lalo o 1200rpm);

二、 ka helu o kēia manawa;

Pili ke au i ke anawaena a me ka helu o ka huli ana o ka wili wiliwili. ʻO ka ʻōlelo maʻamau, ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i ka torque no nā kaʻa e like me ka nui like, akā ʻoi aku ka maikaʻi o nā hiʻohiʻona kiʻekiʻe o nā motika me ka nui o kēia manawa ma mua o ka poʻe me ka helu liʻiliʻi;

三、inductance;

ʻO ka Inductance kekahi mea kī nui no nā kaʻa stepper, e like me ka nui o ka mīkini, kahi inductance nui ʻo ia ka liʻiliʻi o ka mīkini helu i kēia manawa, a ʻaʻole maikaʻi ka torque kiʻekiʻe e like me ka mīkini inductance liʻiliʻi;

四、Mechanical precision;

rotor i luna a i lalo ʻelua ʻāpana o ka pololei o ka niho a me ke koena o ka ea stator-rotor ma waena o ka pololei (nā kūlana kūpono unilateral air gap 0.04mm), pili nui i ka torque hana o ka kaʻa a me ka maʻalahi o ka hana;

五、 Māhele;

ʻElua ala e hōʻike ai i ka mahele o nā kaʻa stepper; N (400, 1000, 5000, 6400, a me nā mea'ē aʻe), N pulses / huli; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, etc.), M mahele;

Ka hoʻololi ʻana: ʻelua-phase motor (1.8 ° step angle) kaʻa, no ka laʻana, ʻaʻohe māhele (1 subdivision), ʻae ke kaʻa i ka 360 ° / 1.8 ° = 200 pulses, huli ke kaʻa i ka pōʻai N = 200 * M;.

六、 current;

ʻElua mau manaʻo o kēia manawa: ka mīkini helu i kēia manawa a me ka hoʻonohonoho hoʻonohonoho o kēia manawa. I ka hoʻohana ʻana, hoʻonohonoho ka mea hoʻokele i kēia manawa ≤ motor i helu ʻia i kēia manawa * 1.2, inā ʻaʻole, hiki ke wela ke kaʻa;

七、 Unipolar a me ka bipolar;

ʻElua mau manaʻo o ka unipolarity a me ka bipolarity:

1, motor: unipolar a bipolar;

2, hoʻokele: unipolar a bipolar; Hiki i ke kaʻa unipolar ke hoʻokele i ke kaʻa unipolar wale nō, hiki ke hoʻokele i ke kaʻa bipolar a me ka moto unipolar; ka mīkini unipolar e hoʻohana ana i ka unipolar drive a me ka bipolar drive half winding hopena like;

八、 Hoʻokomo hōʻailona;

ʻElua ʻano hoʻokomo hōʻailona: hoʻokomo hōʻailona hoʻokahi a me ka hoʻokomo hōʻailona ʻokoʻa.

Nā hōʻailona hoʻokahi: 1, maikaʻi maʻamau: hoʻokūkū i ka mea hoʻokele ʻano NPN; 2, ʻino maʻamau: hoʻokūkū ʻano ʻano PNP;

Hōʻailona ʻokoʻa: 1, ʻokoʻa: ka hapa nui o nā kāleka hoʻokele; 2, maikaʻi maʻamau: hōʻailona pōkole hopena maikaʻi; 3, ʻino maʻamau: hōʻailona pōkole hopena maikaʻi ʻole.
