Awesome, thanks for clarification! I'm saving all of this info, might very well need to use it in the future.
So this transformator + rectifier is better option than Switching regulated power unit (links were provided), even if it has enough output for motors to work and not get PS burned out?
And I found another motor, this one is geared:

edit: Switching supply, but with more output current - 30A and 360W BUT only 12V - so that means lower speed of the motors right? Is it worth to sacrifice speed if the motor (
