We had 2 motors burn out today, and we have a 30 amp breaker on it ( your only supposed to use the 30's I believe... not the 40's ) I think you were also a bit off on the stall I think its only at 58 amps.

However, just because you have a 30 amp fuse on it.. it can still spike above for a short period of time before the breaker trips or you blow the fuse. You could be spiking for a few seconds getting it really hot and then off. Thats what seems to happened to ours.

Also, be careful not to run them for too long at under too high of torque. It seems in our motors the insulation actually burned off and the coils began to touch. Shorting the motors and binding them up quite a bit. They would still work but when ne sort of torque was applied to it.. Smoke everywhere.

All in all, our team seems to finding that what these motors are " rated " at don't seem to be holding true. We doubled up on the motors and had extreme overkill ( as in 1 motor could do all the work ) and made sure with amp current sensors that we had an equal share and they still burned out very quickly when it locked for a very short second.

They heat up quickly, so let them cool off a bunch don't run them constantly, and try to keep the amps down around 20.. their constant running is rated at 28 amps their techinical " safe zone. " So try to shoot below.. when in doubt overkill but if you can't.. make sure you make sure! that they are running correctly..

These are but generals, I can't come to particulares without knowing your system better or offer ne other advise .. all I can say those fp's can be a pain so be careful with them. Bring plenty of spares to comps.
