Inkcazo yeeparameter ze-stepper motor (I)

一, i-torque yokubamba;

I-torque efunekayo ukuze kujikeleziswe i-output shaft ye-motor xa izigaba ezibini ze-stepper motor windings zinikwe amandla nge-DC current elinganisiweyo. I-torque yokubamba inkulu kancinci kune-torque ebalekayo kwisantya esiphantsi (ngaphantsi kwe-1200rpm);

二、 umsinga olinganisiweyo;

Umbane unxulumene nobubanzi kunye nenani lokujika kwekhoyili ejikelezayo. Ngokubanzi, i-torque yokubamba ilingana ngokusisiseko kwiimoto ezilingana nobukhulu obufanayo, kodwa iimpawu zesantya esiphezulu zeemoto ezine-current enkulu elinganisiweyo zingcono kakhulu kunezo zine-current encinci elinganisiweyo;

三、 inductance;

I-Inductance ikwayiparameter ebalulekileyo yeemoto ze-stepper, ezihambelana nemoto enobukhulu obufanayo, i-inductance enkulu ithetha ukuba umbane olinganiswe yimoto umncinci, kwaye i-torque yesantya esiphezulu ayilunganga njengemoto encinci ye-inductance;

四、Ukuchaneka koomatshini;

i-rotor phezulu nasezantsi amacandelo amabini okuchaneka kwamazinyo okungalunganga kunye nebhalansi yesithuba somoya se-stator-rotor phakathi kokuchaneka (iimeko ezifanelekileyo isithuba somoya esingaphantsi kwesinye i-0.04mm), ikakhulu ichaphazela i-torque yokusebenza kwemoto kunye nokuthamba kokusebenza kwayo;

五、 Ulwahlulo;

Kukho iindlela ezimbini zokubonakalisa ukwahlulwahlulwa kweemoto ze-stepper; i-N (400, 1000, 5000, 6400, njl.njl.), ii-N pulses/turn; i-1/M (1/2, 1/5, 1/25, 1/25, 1/32, njl.njl.), ukwahlulwahlulwa kwe-M;

Ukuguqulwa: i-drive yemoto enamanqanaba amabini (i-1.8 ° step angle), umzekelo, akukho candelo (1 candelo), i-drive yamkela ii-pulses ezingama-360 ° / 1.8 ° = 200, i-motor ijika isangqa N = 200 * M;.

六, okwangoku;

Kukho iingcamango ezimbini zamandla angoku: amandla angoku alinganiswa yimoto kunye namandla angoku ahleliwe yidrive. Xa usebenzisa, amandla angoku amiselwa ngumqhubi ≤ amandla angoku alinganiswa yimoto * 1.2, kungenjalo, imoto ingatsha;

七、 Unipolar kunye ne-bipolar;

Kukho iingcamango ezimbini ze-unipolarity kunye ne-bipolarity:

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

2, ukuqhuba: i-unipolar kunye ne-bipolar; i-unipolar drive inokuqhuba kuphela i-unipolar motor, i-bipolar drive inokuqhuba i-bipolar kunye ne-unipolar motor; i-unipolar motor esebenzisa i-unipolar drive kunye ne-bipolar drive isiphumo sokujika i-half winding siyafana;

I-八、 Iingeniso zeSignali;

Kukho iintlobo ezimbini zokufaka isignali: ukufaka isignali enesiphelo esinye kunye nokufaka isignali eyahlukileyo.

Imiqondiso ephela ngomda omnye: 1, into elungileyo eqhelekileyo: isilawuli sohlobo lwe-NPN esihambelanayo; 2, into embi eqhelekileyo: isilawuli sohlobo lwe-PNP esihambelanayo;

Isignali yokwahluka: 1, umahluko: uninzi lwamakhadi olawulo lwentshukumo; 2, i-common positive: isiphelo sesignali positive esifutshane; 3, i-common positive: isiphelo sesignali positive esifutshane.
