Hey Guys,
I have a MT4-G3 and I am finding my motor is getting to the point where you can't touch it due to heat. Are heatsinks worth it? I have heard that due to the magnets not touching the can that heatsinks don't work. As it's warming up here in Australia I thought it's time to do something.
Any advice would be greatly appreciated
Cheers

What I have heard is that heatsinks only cool down the can and not inside the motor giving false readings..Not sure how true this is

The heat is created in the windings. Why would a magnet get hot from moving through a magnetic field? It wouldn't. A heatsink dissipates the heat created by the windings, thus allowing less heat to be transfered to the rotor. I know, thermodynamics are difficult to understand.

If it ran coolish before and is running hot now maybe bearings need to be replaced or something else is causing drag that wasn't there before. Maybe even motor bearings? The motor temps would not vary that much with the weather heating up a bit.
As said above, heatsinks do help. If you can cool down the can, your motors internals will be cooler. Hence fins on some motors cans. If the manufacturers didn't see a cooler motor from machining edges in the can, they wouldn't do it. The can works as a heatsink itself along with it's other jobs.
Find where your problem is first though, don't band-aid it with a heatsink. Once you found where the drag is coming from, add a heatsink to your already cooler running happy motor.
