Hi guys,
I am controlling speed of motors using a PWM microcontroller board having 5 Amp drivers. It works fine for small DC motors running at 12 VDC.
I now have a heavy DC motor (1 hp, 180 Vmax, 5 Amax). I am planning to use LM741 as an inverting amplifier with gain 15 to amplify the output of the PWM signal by which I can control speed of this motor.
Is this the correct solution? Any better solutions welcome.
