Whenever I've tried to read PWM signals with my DMM - I may as well have guessed the figures.
I actually thought it's not a good way to measure PWM values with DMM, but while experimenting with a LED, it showed quite likely results, so I started believing it.
which you don't want to.
I didn't say I don't want to, I'm just trying to make out all this electronic things. And I won't be very glad just filtering the PWM to make it as simple DC voltage without understanding the reason for doing it.
It gets hot because of the power not the current.
Oh, this might be the thing I wanted to hear from the very beginning.
As I understand now, during those periods of time, when PWM signal is 5V, the transistor is fully on and lets the huge collector current to run through it. Multiplied on 9.5V (power supply of a motor), it hits the maximum power dissaption (65W) and makes the transistor boil. If it is so, everything falls into place :).
Thanks for links also, will study them..
