temp on motor/esc

[bruce5385]

were should i measure the temp on motor?(on can or at rotor) also were on esc compacitors or board?

For our purpose of estimating performance in FE boating typically you should measure your motors heat on the end bell approximate to the outer shell. Not inward toward the rotor end shaft. Now thats a generalism. Because its assuming you have a water jacket and that will influence a motors true temperature, so you want to be at some distance away from the motors coolest locations. All a water jacket does is cool the shell and whats approximate. If you really want to know how hot your motor is measure the copper windings if you can get to them with your temp device. Now thats the motors true temperature. While they can cool fast since they are copper, the steel laminations surrounding the windings will not. They will retain heat for much longer. So the copper cannot get much cooler before the steel does.

Measuring heat on an ESC is typically difficult, much like the motor, most decide to use the heat value off the caps. Thats an accepted location but you might find it better to measure right at the heat sink since thats more approximate to the true generators of heat, the FET's.

If your using a laser/infrared gun make sure you do not measure off bright/ shinny surfaces. That can lead in inaccurate readings. Read the guns warnings. Most will list the operation for taking a measurement.
