Incazelo yamapharamitha e-stepper motor (I)

一、Ukubamba itorque;

I-torque edingekayo ukuze kuzungezwe shaft yokukhipha injini lapho izigaba ezimbili zama-stepper motor windings zinikwa amandla nge-DC elinganiselwe yamanje. I-torque yokubamba inkulu kancane kune-torque egijima ngesivinini esiphansi (ngezansi kwe-1200rpm);

二、 umsinga okaliwe;

Umsinga uhlobene nobubanzi kanye nenani lokuphenduka kwekhoyili ejikajikayo. Ngokuvamile, i-torque yokubamba ilingana ngokuyisisekelo namamotho ahambisana nobukhulu obufanayo, kodwa izici zejubane eliphezulu zamamotho anamanje amakhulu akalwe zingcono kakhulu kunalawo anamanje amancane akaliwe;

三, inductance;

I-inductance iphinde ibe ipharamitha eyinhloko yama-stepper motors, ahambisana nosayizi ofanayo we-motor, i-inductance enkulu isho ukuthi i-motor rated current incane, futhi i-torque yejubane eliphezulu ayilungile njenge-motor inductance encane;

四、Ukunemba komshini;

i-rotor phezulu naphansi izingxenye ezimbili zokunemba kwezinyo okungalungile kanye nebhalansi yegebe lomoya we-stator-rotor phakathi kokunemba (izimo ezifanele igebe lomoya elihlangene elingu-0.04mm), lithinta ikakhulukazi i-torque yokusebenza kwemoto nokushelela kokusebenza;

五、 Ukuhlukaniswa iziqephu;

Kunezindlela ezimbili zokuveza ukuhlukaniswa kweziqephu zamamotho ahamba phambili; N (400, 1000, 5000, 6400, njll.), N pulses/turn; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, njll.), ukuhlukaniswa kwe-M;

Ukuguqulwa: i-motor yesigaba ezimbili (i-1.8 ° step angle) idrayivu, isibonelo, akukho ukuhlukaniswa (1 ukuhlukaniswa), idrayivu yamukela i-360 ° / 1.8 ° = 200 pulses, i-motor iphendulela indilinga N = 200 * M;.

六, yamanje;

Kukhona imiqondo emibili yamanje: motor rated current kanye drive set current. Uma usebenzisa, umshayeli usetha okwamanje ≤ motor rated current * 1.2, ngaphandle kwalokho, injini ingashisa;

七、 Unipolar kanye ne-bipolar;

Kunemiqondo emibili ye-unipolarity ne-bipolarity:

1, motor: unipolar kanye bipolar;

2, ukushayela: i-unipolar ne-bipolar; i-unipolar drive ingashayela i-unipolar motor kuphela, i-bipolar drive ingashayela i-bipolar kanye ne-unipolar motor; i-unipolar motor esebenzisa i-unipolar drive kanye ne-bipolar drive uhhafu wokuzungeza umphumela kuyafana;

八, Okokufaka Kwesiginali;

Kunezinhlobo ezimbili zokufakwayo kwesignali: okokufaka kwesignali enesiphetho esisodwa kanye nokufaka isignali ehlukile.

Izimpawu ezinomkhawulo owodwa: i-1, i-positive evamile: fanisa isilawuli sohlobo lwe-NPN; 2, negative evamile: fanisa isilawuli sohlobo lwe-PNP;

Isignali ehlukile: 1, umehluko: amakhadi amaningi okulawula ukunyakaza; 2, iphozithivu evamile: isignali evumayo isiphetho esifushane; I-3, i-negative evamile: isiphetho esinegethivu sesiginali sifushane.
