Tlhaloso ea li-parameter tsa stepper motor (I)

一、Ho tšoara torque;

Torque e hlokahalang ho potoloha shaft ea motlakase ha mekhahlelo e 'meli ea li-winding motor e matlafatsoa ke DC ea hona joale. Torque e ts'oereng e kholo hanyane ho feta torque e mathang ka lebelo le tlase (ka tlase ho 1200rpm);

二、 rated current;

Hona joale e amana le bophara le palo ea ho chenchana ha khoele e tsoelipanang. Ka kakaretso, torque e ts'oereng e lekana hantle le li-motor tse tsamaellanang le boholo bo lekanang, empa litšoaneleho tsa lebelo le phahameng tsa li-motor tse nang le palo e kholo ea hona joale li ntle haholo ho feta tse nang le maemo a manyane;

三, inductance;

Inductance e boetse e le parameter ea bohlokoa bakeng sa li-motors tsa stepper, tse tsamaellanang le li-motor tsa boholo bo lekanang, inductance e kholo e bolela hore motlakase o lekantsoeng hona joale o monyenyane, 'me torque e lebelo le phahameng ha e ntle joaloka mochine o monyenyane oa inductance;

四、Ho nepahala ha mochini;

rotor holimo le tlaase likarolo tse peli tsa ho nepahala leino le fosahetseng le stator-rotor moea lekhalo lekhalo pakeng tsa ho nepahala (maemo loketseng unilateral moea lekhalo 0.04mm), haholo-holo ama enjene tshebetso torque le boreleli tshebetso;

五、 Karohano;

Ho na le mekhoa e 'meli ea ho hlalosa karohano ea li-motors tsa stepper; N (400, 1000, 5000, 6400, joalo-joalo), N pulses/thinya; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, joalo-joalo), karohano ea M;

Phetoho: tse peli-mohato enjene (1.8 ° mohato angle) drive, ho etsa mohlala, ha ho karohano (1 karohano), koloi e amohela 360 ° / 1.8 ° = 200 pulses, enjene retelehela selikalikoe N = 200 * M;.

六、 ea hona joale;

Ho na le likhopolo tse peli tsa hona joale: motlakase o lekanyelitsoeng hona joale le koloi e behiloeng hona joale. Ha o sebelisa, mokhanni o beha hona joale ≤ motor rated current * 1.2, ho seng joalo, motlakase o ka chesa;

七、 Unipolar le bipolar;

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

1, enjene: unipolar le bipolar;

2, khanna: unipolar le bipolar; unipolar drive e ka khanna koloi ea unipolar feela, koloi ea bipolar e ka khanna koloi ea bipolar le unipolar; unipolar motor ho sebelisa unipolar drive le bipolar drive halofo ea matsoelintsoeke phello e tšoana;

八、 Litlhahiso tsa Lipontšo;

Ho na le mefuta e 'meli ea ho kenya lets'oao: ho kenya lets'oao le sa feleng le ho kenya lets'oao le fapaneng.

Matšoao a le mong: 1, e tloaelehileng e ntle: bapisa molaoli oa mofuta oa NPN; 2, e tloaelehileng hampe: bapisa mofuta oa PNP molaoli;

Letšoao le fapaneng: 1, phapang: likarete tse ngata tsa ho laola motsamao; 2, e tloaelehileng e ntle: pontšo e ntle e qetellang e khutšoanyane; 3, tloaelo e mpe: pontšo e mpe qetellong e khuts'oane.
