Tlhaloso ea liparamente tsa enjene ea stepper (I)

一, torque e tšoereng;

Torque e hlokahalang ho potoloha shaft ea tlhahiso ea enjene ha mekhahlelo e 'meli ea li-winding tsa enjene ea stepper e matlafatsoa ka motlakase oa DC o lekantsoeng. Torque ea ho tšoara e kholo hanyane ho feta torque e mathang ka lebelo le tlase (ka tlase ho 1200rpm);

二、 hona joale e lekantsoeng;

Motlakase o amana le bophara le palo ea ho reteleha ha coil e kobehang. Ka kakaretso, torque ea ho tšoara e lekana hantle bakeng sa lienjene tse tsamaellanang le boholo bo tšoanang, empa litšobotsi tsa lebelo le phahameng tsa lienjene tse nang le motlakase o moholo o lekantsoeng li betere haholo ho feta tse nang le motlakase o monyenyane o lekantsoeng;

三, inductance;

Inductance le yona ke parameter ya bohlokwa bakeng sa dienjene tsa stepper, tse tsamaellanang le enjene ya boholo bo tshwanang, inductance e kgolo e bolela hore motlakase o lekanyeditsweng ke enjene o monyane, mme torque ya lebelo le phahameng ha e ntle jwalo ka enjene e nyane ya inductance;

Ho nepahala ha mechini;

rotor ho ea holimo le tlase likarolo tse peli tsa ho nepahala ha leino le fosahetseng le ho leka-lekana ha lekhalo la moea la stator-rotor pakeng tsa ho nepahala (maemo a loketseng lekhalo la moea la lehlakore le le leng la 0.04mm), haholo-holo ho ama torque ea ts'ebetso ea enjene le boreledi ba ts'ebetso;

五、 Karohano;

Ho na le litsela tse peli tsa ho hlalosa karohano ea li-stepper motors; N (400, 1000, 5000, 6400, jj.), N pulses/turn; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, jj.), M karohano;

Phetoho: enjene ea mekhahlelo e 'meli (sekhutlo sa mohato oa 1.8 °), mohlala, ha ho na karohano (karolo e le 'ngoe), enjene e amohela li-pulse tsa 360 ° / 1.8 ° = 200, enjene e potoloha selikalikoe N = 200 * M;.

六、 ea hona joale;

Ho na le mehopolo e 'meli ea hona joale: hona joale e lekantsoeng ke enjene le hona joale e behiloeng ke drive. Ha o sebelisa, mokhanni o beha hona joale ≤ hona joale e lekantsoeng ke enjene * 1.2, ho seng joalo, enjene e ka 'na ea cha;

七、 Unipolar le bipolar;

Ho na le mehopolo e 'meli ea unipolarity le bipolarity:

1, enjene: e polar le e ferekanyang maikutlo;

2, kganna: unipolar le bipolar; unipolar drive e ka kganna feela unipolar motor, bipolar drive e ka kganna bipolar le unipolar motor; unipolar motor e sebedisang unipolar drive le bipolar drive half winding e tshwana;

八、 Likenyelletso tsa Matshwao;

Ho na le mefuta e 'meli ea ho kenya lets'oao: ho kenya lets'oao le nang le pheletso e le 'ngoe le ho kenya lets'oao le fapaneng.

Matshwao a fellang ka motsotso o le mong: 1, ntho e tloaelehileng e ntle: taolo ya mofuta wa NPN e tshwanang; 2, ntho e tloaelehileng e mpe: taolo ya mofuta wa PNP e tshwanang;

Letšoao la phapang: 1, phapang: boholo ba likarete tsa taolo ea motsamao; 2, kakaretso e ntle: lets'oao le ntle qetello e khutšoanyane; 3, kakaretso e mpe: lets'oao le mpe qetello e khutšoanyane.
