Incazelo yamapharamitha e-stepper motor (I)

一、I-torque yokubamba;

I-torque edingekayo ukuze kujikelezwe umgodi wokukhipha wemoto lapho izigaba ezimbili ze-stepper motor windings zinikwa amandla nge-DC current elinganisiwe. I-torque yokubamba inkulu kancane kune-torque egijimayo ngesivinini esiphansi (ngaphansi kuka-1200rpm);

二、 i-current elinganisiwe;

Ugesi uhlobene nobubanzi kanye nenani lokujika kwekhoyili egoqayo. Ngokuvamile, i-torque yokubamba ilingana ngokuyisisekelo nezinjini ezilingana nosayizi ofanayo, kodwa izici zesivinini esikhulu zezinjini ezinegesi elikhulu elilinganisiwe zingcono kakhulu kunezo ezinegesi elincane elilinganisiwe;

三, inductance;

I-inductance nayo iyipharamitha ebalulekile yama-stepper motors, ahambisana ne-motor enobukhulu obufanayo, i-inductance enkulu isho ukuthi ugesi olinganiselwe yi-motor mncane, futhi i-torque yesivinini esikhulu ayilungile njenge-motor encane ye-inductance;

Ukunemba komshini;

i-rotor phezulu naphansi izingxenye ezimbili zokunemba kwamazinyo okungalungile kanye nebhalansi yegebe lomoya le-stator-rotor phakathi kokunemba (izimo ezifanele igebe lomoya elingahlangene nelinye i-0.04mm), ikakhulukazi kuthinta i-torque yokusebenza kwemoto kanye nokushelela kokusebenza kwayo;

五、 Ukuhlukaniswa iziqephu;

Kunezindlela ezimbili zokuveza ukwahlukaniswa kwama-stepper motors; i-N (400, 1000, 5000, 6400, njll.), ama-N pulses/turn; i-1/M (1/2, 1/5, 1/25, 1/25, 1/32, njll.), ukwahlukaniswa kwe-M;

Ukuguqulwa: idrayivu yemoto enezigaba ezimbili (i-angle yesinyathelo esingu-1.8 °), isibonelo, akukho ukwahlukaniswa (ukwahlukaniswa okungu-1), idrayivu yamukela ama-pulse angu-360 ° / 1.8 ° = 200, i-motor ijika indilinga N = 200 * M;.

六, yamanje;

Kunemibono emibili yamanje: ugesi olinganiswe yinjini kanye nogesi obekwe yidrayivu. Uma usebenzisa, ugesi olinganiswe yidrayivu ≤ ugesi olinganiswe yinjini * 1.2, ngaphandle kwalokho, ugesi ungasha;

七、 Unipolar kanye ne-bipolar;

Kunemibono emibili ye-unipolarity kanye ne-bipolarity:

1, injini: i-unipolar kanye ne-bipolar;

2, ukushayela: i-unipolar kanye ne-bipolar; i-unipolar drive ingashayela kuphela i-unipolar motor, i-bipolar drive ingashayela i-bipolar kanye ne-unipolar motor; i-unipolar motor esebenzisa i-unipolar drive kanye ne-bipolar drive half winding effect iyafana;

Okungenayo kwesignali;

Kunezinhlobo ezimbili zokufaka isignali: ukufaka isignali okunesiphelo esisodwa kanye nokufaka isignali ehlukile.

Izimpawu eziphela ngokuphela: 1, okuhle okuvamile: isilawuli sohlobo lwe-NPN esihambisanayo; 2, okubi okuvamile: isilawuli sohlobo lwe-PNP esihambisanayo;

Isignali yokuhlukanisa: 1, umehluko: amakhadi amaningi okulawula ukunyakaza; 2, okuhle okuvamile: ukuphela okuhle kwesiginali; 3, okubi okuvamile: ukuphela okubi kwesiginali.
