After some research in the web and some test this is my last version of a motor controlor. I'm not very good in electronic but It's working great. I put the fire on it after running it back and foward at 100% whit a car fan motor for charge for 2 hour stress test and no heat sink and ventilation. 1 mosfet dead and a other not very good anymore. If someone can verify if I can make some upgrade I will appreciate.
Source, a car batterie!
Control by a arduino on a pwm pin!
