8051 Microcontroller se Stepper motor kaise interface kre in Hindi

8051 Microcontroller se Stepper motor kaise interface kre in Hindi:

Bahut se log apne project design m stepper motor use krte hein or unko exact pta nhi hota k stepper motor ko kaise interface kiya jaata h kisi microcontroller se, to chaliye baat krte hein “8051 Microcontroller se Stepper motor kaise interface kre in Hindi”.

Stepper motor bahut si applications m use ki jaati h jaise ki industrial, medical, consumer electronics etc. Jaha bhi hme kisi object ki precision rotation or positioning ki requirement hoti h vha stepper motor hi use ki jaati h.

Stepper Motor (in Hindi)

8051 Microcontroller se Stepper motor kaise interface kre in Hindi

Stepper motor ek brush less motor hoti h jo electrical pulses ko mechanical rotation m convert krti h. Ye input pulse k according steps m rotate krti h. Motor ka step size uske number of phases or rotor k number of Teeth pr depend krta h. Rotor k ek step m hue angular displacement ko motor ka Step size kehte hein.
Agr stepper motor k 4 phase or 50 Teeth hein to ye pura ek rotation complete krne m 4*50=200 steps lega or iska step angle 360/200= 1.8 degree hoga.

Types of Stepper Motor

1). Unipolar stepper: Unipolar stepper m normally 5 yaa 6 wires hote hein. Isme 4 coils hoti hein jiske 4 wires hote hein or 2 comman wires hote hein jaisa k picture m dikhaya gya h.

2). Bipolar stepper: Ye motor forward or reverse dono directions m move krti h. Isme sirf 4 wires hote hein or koi bhi comman wire nhi hota.

Stepper motor ko 8051 microcontroller se interface krana bahut asaan h bs hme iske 4 wires pr 0 or 1 logic apply krna h. Motor inerface ki coding m yha niche de rha hu.

Hm yha Unipolar stepper use kr rhe hein jiski coils ki 4 pins ko hmne 8051 microcontroller k Port2 se interface IC ULN2003A k through connect kiya h. Motor k comman points pr proper 12 volt power supply connect kr dein.

Microcontroller motor ki coils ko drive krne k liye enough current nhi de paata isliye hmne yha pr current drive IC ULN2003A ka use kiya h.
IC ULN2003A m 7 pins input ki hoti hein, 7 pins output ki or do power supply or Ground ki hoti hein. Hm yha sirf 4 input pins or 4 output pins use kr rhe hein.
Aap yha current amplification k liye ULN2003A k replace m IC L293D bhi use kr sakte hein.

Stepper motor k wires ko kaise justify kre:

Stepper motor m sbse pehle ye pta krna hota h k phase wires kon kon se hein or comman wire kon se. Aapko multimeter ko resistance pr set krna h or wires ke beech ka resistance measure krna h.
Comman point or kisi ek phase wire k beech apko kuch resistance show hoga usko note kr lein. Agr kisi coil k same wires k beech resistance mesaure krte hein to Commant point or phase wire k resistance se double resistance milega. Do different phases k wires k beech koi bhi resistance show nhi krega.

 

Circuit design kre:

Yha circuit design k according hi apna design kre.
Ceramic capacitor C1 or C2 k saath 11.0592 MHz ka crystal oscillator clock generate krne k liye use kiya jaata h jise microcontroller ka heart bhi kaha jaata h, bina iske controller operate nhi krta.
Resistance R1 or capacitor C3 microcontroller k liye reset circuitry design krte hein.
Controller ki Port2 ki 4 pins ko IC ULN2003A ki 4 pins se connect kre or baaki 2 pins power supply (12volt) se connect kre.

C Programming in Hindi:

C program yha se copy nhi hoga isliye m yha aapko download link de rha hu, usko open krke aap vha se prohram ko copy kr sakte hein.
#include<reg51.h>
void delay(unsigned int msec)
{
unsigned i,j ;
for(i=0;i<msec;i++)
for(j=0;j<1275;j++);
}
void main()
{
while(1)
{
P2=0x01;
delay(1);
P2=0x02;
delay(1);
P2=0x04;
delay(1);
P2=0x08;
delay(1);
}
}
