Hi.. I'm building a light follower type bot.. i'm using a basic opamp, n 2 power bjts for driving da motor.. havent used a specific refernce circuit.. Driver circuit is working fine..but i has 1 prob..
I'm using a PNP MJE2955 n NPN MJE3055.. THey're complementary pair.. icmax is 10 A..
Now, i'm usng a Vcc of four 1.5V batteries.. I thus get 6v n around 1.5A as input to the driver ckt.. But on the output i get only 0.5A.. So da motor with a wheel runs in air, but on ground it dosent get that much force.. So i wanted to increase the output current to atleast 1A.
Any suggesions? I cant put in more batteries.. i mean 8 batt wud giv me 1A, but it wud b heavy then..
So, lukin forward for fiddling with the transistors..
Plz give your valuable suggestions..
Thank you..
