All good to hear chaps.
Like you say, the driving style and grip will determine temps and longevity. All the motor failures I've had have been brushes wearing out and dropping off their copper spring mounts. I wonder how long they will run for, continuously from new? I expect all teams will suffer similar wear rates and all the motors will die within an hour of each other. Whether that's after 5 hours or 25 hours we shall see! All I know is we'll be starting with a fresh motor right out of the packet. No amount of extra cooling will reduce brush wear, but it might improve performance by reducing magnet temperatures. That in turn might actually promote brush wear by offering extra torque/revs.... we shall see
I hear some teams are trying different drive shafts etc, I hope that is frowned upon as we are trying to run the standard cars to keep costs down. I see there is a heavy motor plate heatsink available as an aftermarket upgrade, similarly I doubt that would be allowed, though home made clip on motor heat sinks will of course be allowed I expect. John?
