I do at times but it's never long running stuff. A bit here and there. So I seriously doubt there would be any issues doing it that way. And it's not often. For sure I do more in the upper 80s so i

Here calculations for mini lathe in ambient temperature 104°F? [40°C] Motor rize in temperature 60°C Hot spot 5°C Total is 105°C Then check your insulation temperature along below you good

Using a mini lathe and other tools in 2004 most of time temperature of 105°F and maybe spikes to 108°. Today the temperature is over 108° and days to 113°F So odds of burning the mini lathe motor

A few months I add a temperature gauge to my lathe and the Calc on how down does a mini lathe motor gets. If go on internet you all garbage formulas on this subject for just few degrees.? But

Gerald you are right about Global Warming you can easily debunk it with a little research it is only making someone very rich.

This is gradually turning Into a discussion of politics which, some of us will remember, is what destroyed the 7x10 minilathe group. Let's not go down that road. Mike

While acknowledging that there are natural cycles of the earth heating and cooling, we also have to look at what drives feedback for those systems, and perhaps several of the changes made by man, such

We feel humidity as making the heat worse because our bodies are cooled by evaporation. humidity slows down the evaporation process. But this does not apply to motors. The more modern way to use

Most motors have? ambient temperature of 105°F [40°C] Now live a hotter location a reduced in horse power. Here simple clip on motors . It max winding temperature you watch for. If look on

Haven't heard that name in a while...

And now you also know one of the reasons why motors used in the lunar and Mars rovers, and in similar applications require so much engineering. When there is no atmosphere, you are left with only

Yeah, we went around and around on this a while back. The concept of “it’s the melting point of the enamel on the motor coils” that sets the temperature limit seems to have escaped Dave.

And if anyone isn’t aware, brushes have different hardness grades. The trade off is soft brushes need replacing more often but don’t wear the commutator, and the opposite for hard ones. Of

Whole lot of “maybes” in that article. Also says the excess water will be up there for “maybe 10-15 years”, while if you read the actual paper is says “maybe 5-10 years”, so who know what

If remember NEMA ia at sea leave I think at 40% humidity. So high you go less cooling. I have different outside temperature most are 105°F max for maximum horse power. If go hot hotter you need

Nope, that is not how it works. Per NEMA, the maximum ambient temp is 40C (104F). There is a required reduction for altitude (up to 1000m 40C, up to 2000m 30C, up to 3000m 20C). The IEC ratings are

Yes I can see now from the closer photo that the holder is molded as part of the end cap so clearly not a separate piece. I suppose the complete motor end cap complete with brushes might be available
