Need advice on motors, gearboxes, and ESCs

CIMs are able to cool off all right because of the surface area and size of the motor. BAG motors just overheat all the time!

I agree that pulling 100 amps continuously from a motor means that you are doing something wrong. That is nearly the max threshold of CIM windings!

I doubt speed was the root cause of the BAG motor failure. Improper side-loading on the bearing due to a shaft-mounted shooter wheel or an overtensioned belt was likely a root cause if the bearing itself failed.
