Measuring Motor Temps

[JackWood]

Hi,

What do you use to measure motor temps?

I have a Cat SX with Losi Xcelorin ESC and Motor. Is it normal for the motor to get to the temperature that it would bubble the paint on the inside of tray adjacent to the motor?

Thanks in advance.

A lot of people now seem to be using the IR temp guns that have been used in nitro for a while, it's a bit more precise than your finger (which is what I still use)!

I've never seen a motor flake paint before but that may be a reflection of the paint you are using rather than the temperature itself.

maplin - £15 for a IR pocket temp gun

If you're having paint bubble, then the motor is probably pretty hot to say the least. General rule of thumb is that if you can put your finger on it for 5 seconds or more without scalding yourself, then temps are probably safe...but it's a *very* good idea to grab yourself a temp gun to be sure. For £15, you could save your motor from cooking alive. Losi recommend not exceeding 190F with their motors, as doing so will run the risk of demagnetising the rotor; which is a very bad thing. Ideally though, you don't want the motor to be hitting over 160-170F, tops.

Are you still running that crazy pinion? Might be making it run hot...

Running a 19T now.

But this is not racing, and very very few bursts of full throttle.

I'll try and get an IR temp gauge.

Thanks for all the info. Very helpful.

Cheers
