Post your code and we should be able to rewrite it so that both motors go in the same direction. However, you can just switch the motor wires if you want.

So the speed and current draw and everything is the same in clock-wise and counterclockwise?


In theory I guess, but I think I have a motor which runs more slowly in one direction. I never investigated further though....


Some DC motors are intended to only spin one way - but most are happy to reverse.  If it goes a noticeably
different speed for the same voltage in the other direction something is wrong, there must be significantly more
friction on one direction, or the commutation point is advanced for greater efficiency with the rated load.

is possible with arduino to control a big electric motor ex 200 watt dc?

how can i study and understand the way to control this motor?

is there a book?

You might want to start your own thread.
I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.

Enrico, there is virtually no limit to what an arduino board can control, for instance, I have successfully controlled my milling machine spindles which has 2 by 2HP three phase electric motors on it! The trick is that the arduino board won't power these sorts of things directly (obviously), so you need to find something to interface with it, eg relays or in my case, a VFD (Variable Frequency Drive) which has a serial port interface. Also, when you get to these bigger items, you need to make sure your board is isolated from any feedback from these motors to protect your board and to ensure it functions properly.
