dc motor interface with 8051

[pradeep23]

hi everyone i want to program for dc motor interface with 8051 using c language ....in that i want to control the dc motor speed using pwm ....i don't know how to generate the pwm please give me some reference to that program or give some good web links to find about that.....thanks......

this link is very useful to u.....

this link is useful for pic16f877a pwm motor control.....

Also for the power section that will drive the motor u can use
L293 ----> if the motor current below 1A
L298 ----> if the motor current below 2A
or u can build a MOSFET H bridge if your motor current is larger

how to drive a dc motor using PWM ....

- - - Updated - - -

i want to program for that in C language....in that first i want run the motor and stop the motor using PWM.... can anyone help in that i am using this circuit only currently.......

first you need to disconnect EN1 & EN2 of L293D from Vcc. then put it to a PIN of your controller and then make a PWM like ON and OFF ing that perticular PIN.speed of that toggling will increase the speed of the motor and will also decrease the speed with slowing the switching

sorry i changed the circuit i am using this only

- - - Updated - - -

in that i take that pin 2 & 7 as input and 1 is for enabling in that how can i generate pwm to run the run the motor i want to run the motor using pwm concept only.... i dont know how to do that .....please help us

 

[thunderboympm]

connect the EN2 also to PWM.

What is you problem in running a motor with pwm and stopping it?

 

[Hz2020]

i want to run the motor using pwm concept only.... i dont know how to do that .....please help us

if u only want to run the motor or stop it, PWM is not necessary.
PWM is used only for speed control.

If u want a PWM code, U should inform us about your controller.

how to do that for controller in 8051.....

i dont know how to give PWM for 8051 controller .........

 

[pradeep23]

ok if i want to control the speed of dc motor what can i do for that i need to program in c language then i need to change my circuit or please provide any circuits or web links to me it will be useful to me
