That looks messy, so I presume you are saying you had a faulty motor that has taken out the board rather than a faulty component on the board. If you are going to replace the motor & the board I would be inclined to fit an inline fuse & holder into the motor supply wire & tie wrap it into the harness in the area of the pcb. if you are wanting to prevent a repeat performance.
Although I would have said you were pretty unlucky as that's not the sort of thing you see often.
