Here is my 555 timer based PWM motor speed controller. This uses a MTP75N03HDL power MOSFET which is good for up to 75A and triggers at logic (+5V) levels, so it was a perfect fit for this circuit. The final application will be a 3/4HP 24V motor that will be going on an electric tractor/ go cart I will be building. Videos of that will be coming soon.
it seems like you are controlling the frequency not the pulse width.
