Hi  
My name is Silvio e y love eletronic circuit for bobbies.  
My project is a PWM motor DC controler, but i can’t understand what is a problem with my Fritzing project, that not simulate a variable DC or CC to simulate a motor variable DC.

Best bet is to upload the sketch (the .fzz file, upload is 7th icon from the left in the reply menu which you appear to already know.) That would allow us to try it and see if it works for us. Before that insure that all the parts in your sketch have spice data like this for the motor
