I need circuit give me 1000 MA

[Muthanna]

Hi :

I am new and beginner in electron and hope to get u r help.

I need a circuit give me 12V with 1000 MA or up using transistors because I want to drive a stepper motor with 12-24 V & 1000 ma .
pleas I want the circut with numbers of all parts


thankx

It will take considerable time and expense to build this circuit. What is your bid, and can I receive your mark when you submit it?

Hey... get your notations right... 1000MA is different from 1000mA

MA = Mega ampere
mA = Milli ampere

There are some driver ICs available... look for them - They may be H Bridges or use transistors like SL 100/ SK 100 oe any of the ones with Ic >1400mA

wow , sorry ..

can u give me the complete circuit ??

Hi,

I use this circuit for my motors.

Not an extraordinary design but working not so bad.

Thank u

Alain what is the max current out from this circuit ?

 

[AlainB]

It will give you the one amp. you need.

It is rated at 5 amp. My motors are rated at 1,2 amp. The transistor are not heating a lot but I did put huges heat sinks with fans anyway. But it is not really needed.

You can easily find datasheets on the web.
