Important note - fuses must be sized to match the SMALLEST size wire in the circuit you are trying to protect... This is particularly important in systems where there is a large difference between the thinnest and thickest wires, as the thinnest wires will develop almost all the heat if there is a short. (they have a higher resistance than the thick wires, so they will drop more voltage across their length...)
The motor label doesn't have enough information on it to be useful - it says 12V, but doesn't give Amp or Watt values, and it isn't possible to solve an Ohm's Law problem with only one known variable... You also didn't say what the motor was used on in a useful way, or give a big enough picture to show what it's driving or estimate the size... However from the "Motion" brand label, I'm guessing that it's an actuator motor, and probably about the size of a soup can... If so, the wires going to it are probably AWG 16 or 18, and it will draw about 10-20A at stall, less when running, If so, a 10 or 15A fuse is about the right size....
