Re: FPs Gone Exothermic

One should note that even the older, 12 volt rated, motors are also prone to failure.

Basically it doesn't matter what FP motor you use if you don't design with it's limitations in mind. If you stall it, it will smoke and die. If it is under load, it will heat up. Who doesn't know the smell of fried FP motors?

100 watts is a lot for that little can. 400 is sadistic. 12 volt motors will last a little longer, but if you beat on them, they'll give up to.

All that said, we are going to try to run with the kit motors. The extra speed and torque are worth the risk to us. If/when they toast, we'll switch over to the 12 volt motors. We think with attention we've paid to keeping vents open and careful current monitoring, we can pull it off.

Theres no such thing as a safe FP motor.
