Sharaxaadda xuduudaha matoorka stepper (I)

一、Xoogga haynta;

Xuddunta loo baahan yahay si loo rogo usha soo saarista matoorka marka labada weji ee wareegga matoorka stepper-ka lagu tamareeyo koronto DC ah oo la qiimeeyay. Xuddunta haysa ayaa wax yar ka weyn wareegga socda ee xawaaraha hooseeya (ka hooseeya 1200rpm);

二、 hadda la qiimeeyay;

Haddaynu ku socono waxay la xiriirtaa dhexroorka iyo tirada wareegyada gariiradda wareegaysa. Guud ahaan, xoogga qabashada ayaa asal ahaan la mid ah matoorada u dhigma cabbirka isku midka ah, laakiin sifooyinka xawaaraha sare ee matoorada leh hadda weyn ayaa si weyn uga wanaagsan kuwa leh hadda yar oo la qiimeeyay;

三,dhaqaajin;

Inductance sidoo kale waa halbeeg muhiim u ah matoorada stepper, oo u dhigma matoorka cabbirka isku midka ah, inductance weyn macnaheedu waa in matoorku uu yar yahay, iyo wareegga xawaaraha sare uusan u fiicnayn sida matoorka inductance yar;

Saxnaanta farsamada;

rotor-ka kor iyo hoos laba qaybood oo saxnaanta ilkaha khaldan iyo dheelitirka farqiga hawada ee stator-rotor ee u dhexeeya saxnaanta (xaaladaha ku habboon farqiga hawada ee hal dhinac ah 0.04mm), waxay inta badan saameysaa wareegga shaqada ee matoorka iyo simanaanta hawlgalka;

五, Qayb-hoosaad;

Waxaa jira laba siyaabood oo lagu muujin karo kala-qaybsanaanta matoorada stepper-ka; N (400, 1000, 5000, 6400, iwm.), garaaca N/leexashada; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, iwm.), hoosaadka M;

Beddelidda: matoor laba-waji ah (xagal tallaabo 1.8 °) wadista, tusaale ahaan, qayb-hoosaad la'aan (1 qayb-hoosaad), darawalku wuxuu aqbalaa 360 ° / 1.8 ° = 200 garaac, matoorku wuxuu rogaa goobaabin N = 200 * M;.

六、 hadda;

Waxaa jira laba fikradood oo ku saabsan hadda: hadda lagu qiimeeyay matoorka iyo hadda lagu dejiyay darawalka. Marka la isticmaalayo, darawalka wuxuu dejinayaa hadda ≤ matoorka lagu qiimeeyay hadda * 1.2, haddii kale, matoorku wuu gubi karaa;

七、 Unipolar iyo bipolar;

Waxaa jira laba fikradood oo kala ah laba-geesood iyo hal-bolarity:

1, matoor: hal-boole iyo laba-jibbaarane;

2, wadista: hal-polar iyo laba-polar; darawalka hal-polar wuxuu wadi karaa oo keliya matoorka hal-polar, darawalka laba-polar wuxuu wadi karaa matoorka laba-polar iyo hal-polar; matoorka hal-polar wuxuu isticmaalayaa darawalka hal-polar iyo darawalka laba-polar iyo saameynta badh-winding waa isku mid;

Soo gelitaannada Calaamadaha;

Waxaa jira laba nooc oo gelinta calaamadda ah: gelinta calaamadda hal-dhammaad leh iyo gelinta calaamadda kala duwan.

Calaamadaha hal-dhammaad leh: 1, kuwa guud ee togan: kuwa guud ee koontaroolaha nooca NPN; 2, kuwa guud ee taban: kuwa guud ee koontaroolaha nooca PNP;

Calaamadda kala duwan: 1, kala duwanaansho: kaararka xakamaynta dhaqdhaqaaqa badankood; 2, togan guud: dhammaadka togan ee calaamadda gaaban; 3, taban guud: dhammaadka taban ee calaamadda gaaban.
