Default Hot Y-Axis Motors

How hot should the Y-Axis Motors get?

I had not previously checked how hot the motors got. I just finished surfacing my spoilboard and I heard a rattle on the left Y Axis motor. Went to go tighten the shroud and accidentally touched the motor. Hot enough to make me jump a bit. Pretty hot to the touch. Wouldn't be able to keep my hand or finger on it for more than a couple seconds.

Will take temp after running my next job, but thought I would post here and ask if it was normal?

Thanks.

Glenn...
Normal operating mode will be around 80* above ambient with no concern below 180* F. Use an IR thermometer to be sure as its hard to tell 150 from 180 "by hand"

This is a during use guide, they should cool down somewhat when idle. If they are over 140* when idle, I would question that also.

I have a stinger II. All my motors run at 122-135 depending on duration and the kind of cutting. My Z axis is usually the hotter mtr because of the 3D cutting. My shop stays between 64deg-70deg year round.


Typical stepper/servo motors are rated around 70-90 C max or 158-194 F.
Size and application will vary temps to a degree. A general rule of thumb is if you can hold on without being burned your mtr is ok. If you are really wimpy the rule doesn't work or if you weld or work in a foundry all day the rule won't work either.

Thanks Guys.

Will take an IR thermometer to them in a bit and report back.

Pete... I may be the "wimpy" variant. I'll work on that ;)
