Sharaxaadda cabbiraadaha mashiinka stepper (I)

一, Qabashada torque;

Wareegga loo baahan yahay inuu ku wareego shafka wax soo saarka mootada marka labada weji ee dabaylaha matoorka stepper lagu tamarsiiyo heerka hadda jira ee DC. Xawaaraha haynta ayaa wax yar ka weyn kan ku ordaya xawaaraha hooseeya (ka hooseeya 1200rpm);

二, hadda la qiimeeyay;

Hadda waxa uu la xidhiidha dhexroorka iyo tirada wareegyada gariiradda dabaysha. Guud ahaan marka la hadlayo, qulqulka xajinta asal ahaan waa siman yahay matoorada u dhiganta isla cabbirka, laakiin sifooyinka xawaaraha sare ee matoorrada leh hadda la qiimeeyay ayaa si weyn uga wanaagsan kuwa hadda la qiimeeyay yar yar;

三,dhaqaajin;

Inductance sidoo kale waa halbeeg muhiim ah oo loogu talagalay matoorrada jaranjarada, oo u dhiganta isla cabbirka matoorka, inductance weyn waxay ka dhigan tahay in matoorka la qiimeeyay hadda uu yar yahay, iyo qulqulka xawaaraha sarreeya uma fiicna sida matoor yar oo inductance ah;

四, Saxnaanta makaanikada;

rotor kor iyo hoos laba qaybood oo ka mid ah saxnaanta iliga qaldan iyo stator-rotor hawo dheelitirka farqiga hawada u dhexeeya saxda ah (xaalad ku haboon farqiga hawada hal dhinac 0.04mm), inta badan saamayn torque hawlgalka matoorka iyo simanaanta shaqada;

五, Qayb-hoosaad;

Waxaa jira laba siyaabood oo lagu muujinayo qayb-hoosaadka matoorada stepper; N (400, 1000, 5000, 6400, iwm.), N garaaca wadnaha / leexashada; 1/M (1/2, 1/5, 1/25, 1/25, 1/32, iwm), M hoosaadka;

Beddelka: motor laba-waji ah (1.8 ° xagal tallaabo) wadista, tusaale ahaan, ma qayb-hoosaad (1 qayb hoosaad), drive aqbala 360 ° / 1.8 ° = 200 garaaca, motor rogo wareeg ah N = 200 * M ;.

六、 hadda;

Waxaa jira laba fikradood oo hadda ah: motor rated current and drive set current. Markaad isticmaalayso, dareewalka dejinaya matoorka hadda ≤ ee hadda * 1.2, haddii kale, matoorku wuu guban karaa;

七, Unipolar iyo laba-cirifoodka;

Waxaa jira laba fikradood oo unipolarity iyo laba-cirifoodka:

1, motor: unipolar iyo laba-cirifood;

2, wadista: unipolar iyo laba-cirifoodka; Wadaadka unipolar-ka waxa uu wadin karaa matoor hal-xidhaale ah oo keliya, laba-cirifoodka waxa uu wadi karaa laba-cirifoodka iyo matoorka unipolar; matoor unipolar ah oo isticmaalaya darawal unipolar iyo laba-cirifoodka saamaynta dabaysha badhkeed waa isku mid;

八, Gelida signalada;

Waxaa jira laba nooc oo signalka gelinta: hal-dhammeedka gelinta signalada iyo gelinta calaamadaha kala duwan.

Calaamadaha hal-dhamaadka ah: 1, togan guud: isbarbardhigga nooca NPN; 2, taban caadi ah: isbarbardhigga nooca PNP;

Calaamadaha kala duwan: 1, kala duwanaansho: inta badan kaararka xakamaynta dhaqdhaqaaqa; 2, togan guud: calaamad dhamaadka togan oo gaaban; 3, taban guud: signal taban dhamaadka gaaban.
