Stepper Motor Driver Using L297 and L298 IC

[umair512]

dear i need your help, am trying to do what u have done, plz help me in a sense that connecting motors to the driver board and computer, i have completed driver board

@umair512

Dear Umair where are you from if I may ask

I'll try to upload a presentation with the plans the motor wiring

And any other relevant stuff needed to complete this project.

Actually I have decided to drop this and buy a ready kit it costs a bit more

But I don't have to build it and lose time (which I don't have)

So it was a good practice.

Good luck

Why are you ussing a heat sink on your l298?

[mechanicalramy]

@jaspers22

This item gets very hot because it relays between the motor and the card

and it consists of transistors wich as you know gets realy hot when switched repeatedly .

hi, do u hace schematics for L298 IC alone used for 12v motor?

[MrRadjevic]

Could you give me schematics ? or link where you found schematics? please :)

@MrRadjevic

I'll try to send it as soon as possible .

I've seen your comment at work so it's not at reach .

I wouldn't mind if you nagged , good day .

@MrRadjevic I have seen one on either the 298 or 297 datasheet.

Love It. You are just like me.

(see my video)

I was building my own drivers but it worked out cheaper to buy them pre- made but I learned a lot

so now i understand it ....., all what you need just 2 wires from the printer port the step and dirction , was the right

[mechanicalramy]

using the L297 would give me a simpler

control over the stepper motor (Number of steps , direction) .

if the stepper motor needs more than 5V to run you won't be able to use the L297

(it can't handle these ratings).

[oqla2000]

i like it allot , but why do you use the L297 while you have l298 ?? i think the l298 can do work alone !!
