I'm new on these boards, I do have a question already though.
As the topic title suggests, I want to control a large DC motor with an Arduino, I havent bought any arduino yet, because I'm not sure which to pick yet.
Now I know there are ways of using mosfet switch to power the motor directly from a battery.
Battery-----Mosfet-----DC-Motor | | Arduino PWM Signal
So the arduino sends a PWM signal to the mosfet, and makes the motor work at a certain % of its power.
However, I have only seen examples of this usage in small motors. Is there anyway I can do this on a larger motor ? different switch or something ?
Edit: I mean something along the lines of a 10 to 15 kw motor.
I hope someone can point me in the right direction.
Kind regards, Sean.
PS: I know there are motor controllers out there (ATX etc.) but whats the fun in that ?
