Tsananguro yematanho emota yestepper (I)

一、Kubata torque;

Torque inodiwa kuti itenderedze shaft inobuda yemota kana zvikamu zviviri zve stepper motor windings zvasimbiswa ne DC current yakarongwa. Torque inobatirira yakakura zvishoma pane torque inomhanya nekumhanya kwakaderera (pasi pe1200rpm);

二、 iyo yakayerwa ikozvino;

Mwenje wemagetsi une chekuita nedhayamita uye huwandu hwekutenderera kwekoiri inotenderera. Kazhinji, torque yekubatirira yakaenzana nemamota akaenzana nehukuru hwakaenzana, asi hunhu hwemota dzinomhanya zvakanyanya dzine magetsi makuru ari nani zvakanyanya pane ane magetsi madiki;

三、inductance;

Kupinza simba (inductance) chinhu chakakoshawo kune mota dzinofamba netsoka, zvichienderana nemota ine saizi imwe chete, kupinza simba kukuru kunoreva kuti magetsi emota ari mudiki, uye torque yekumhanya kwakanyanya haina kunaka semota diki inopinza simba (inductance motor);

Kunyatsorongeka kweMechanical;

rotor kumusoro nekudzika zvikamu zviviri zvekunyatsojeka kwezino uye stator-rotor air gap balance pakati pekunyatsojeka (mamiriro ezvinhu akakodzera unilateral air gap 0.04mm), zvinonyanya kukanganisa torque yekushanda kwemota uye kutsetseka kwekushanda kwayo;

五、 Kugovanisa;

Kune nzira mbiri dzekuratidza kupatsanurwa kwemamota estepper; N (400, 1000, 5000, 6400, nezvimwewo), N pulses/turn; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, nezvimwewo), M subdivision;

Kuchinja: mota ine zvikamu zviviri (1.8 ° step angle) drive, semuenzaniso, hapana kupatsanurwa (1 kupatsanurwa), drive inogamuchira 360 ° / 1.8 ° = 200 pulses, mota inotenderera denderedzwa N = 200 * M;.

六、 current;

Pane pfungwa mbiri dzemagetsi: magetsi ane ratio yemota uye magetsi ane ratio yemota. Pakushandisa, magetsi anoiswa nemutyairi ≤ magetsi ane ratio yemota * 1.2, zvikasadaro, mota inogona kutsva;

Zvimwe, Unipolar uye bipolar;

Kune pfungwa mbiri dze unipolarity ne bipolarity:

1, mota: unipolar uye bipolar;

2, kutyaira: unipolar nebipolar; unipolar drive inogona chete kutyaira unipolar motor, bipolar drive inogona kutyaira bipolar ne unipolar motor; unipolar motor inoshandisa unipolar drive nebipolar drive hafu yekufambisa mafambiro akafanana;

Zviratidzo Zvinopinda;

Kune mhando mbiri dzekupinda kwechiratidzo: kupinda kwechiratidzo chine magumo rimwe chete uye kupinda kwechiratidzo chedifferential.

Zviratidzo zvinogumira chimwe chete: 1, chinhu chakanaka chakajairika: chinodzora mhando yeNPN; 2, chinhu chakaipa chakajairika: chinodzora mhando yePNP;

Chiratidzo chekusiyanisa: 1, musiyano: makadhi mazhinji ekudzora kufamba; 2, common positive: chiratidzo chakanaka magumo mapfupi; 3, common positive: chiratidzo chisina kunaka magumo mapfupi.
