If they are 12 volt motors, use a car battery to test and get set up. You would have to measure the current they are using for each motor and from that , find a power supply.
A switchmode power supply will do. You could use a 20 amp 13.8v power supply in parallel with the battery. Thats a simple setup. I use it as do a few others as well.
