Two questions - can you move (push) the vehicle while in gear (to make sure the motor is not stuck) - did you blow the wire when powering the controller or were you applying 12V directly to the motor?
Note that sometimes something can be thrown up from the street and enter the motor, possibly causing it to get stuck or short. Unless you have blower shrouds completely encasing the motor's air inlets. When applying power to the motor, was this though its power leads and were they still connected to the controller? Unless you power the motor at its terminals, there is still the possibility of the wires being shorted together or the output of the controller shorting the power you are applying. I guess that as soon as you take the brush covers off, you will know more about the internal state of the motor. I have several times towed my previous EV truck home with a blown controller. Just a heavy duty piece of Nylon rope that the Home Improvement store (Orchard Supply was my source) sells by the foot and a towing vehicle that can be anything - in my case a Toyota Prius - and going on local streets, staying under 35MPH since the max safe length of a tow rope makes it impossible to drive faster than that even with the towed vehicle driver hovering their foot over the brake pedal. I bought about 25 ft of rope and double-string it (run it though a tow hook or around a support member on each vehicle) then tie the ends together, so that the distance between the vehicles is about 10 ft. This to avoid anybody will try to squeeze in between the two vehicles. Success!

You might also try "pre-spinning" the motor to reduce the starting surge. I wouldn't give up on that motor so easily. I'm not a motor expert, and someone should correct me if I'm wrong, but from what I've seen, big EV motors seldom if ever fail dead shorted.
