Every electric device is a heater. Some just do other things too.

A brushless motor only converts ~5% of its input to heat. That's low enough that you can reasonably call it a side effect.

Now, a computer, that's a heater that happens to produce math as a side effect. 100% of its input ends up as heat.

Main effect of a brushless motor is moving matter really fast, which, on a molecular level, is same as heating it.
