Hello!

I'm curently doing very similar project.
I was planning to use four independent mosfets and steering them with one PWM signal.
The problem is that for one connected mosfet it works perfectly, but if I connect more mosfets it didn't.
Anynone know what is the problem?
I'm attaching the circuit

Perhaps someone could help if you described what not working perfectly actually means.
