Hi,
What might be missed is that the motor is running unloaded. While it is not at all unusual to run the motor for minutes at a time, the temp rise for an unloaded motor running continuously for 1 hour is interesting.
Best regards,

As others have pointed out this really doesn't seem out of the norm.
Remember what might seem hot to us is just getting warmed up for
electronics. Hot water at about 130F can burn skin yet most
electronics are capable of running just fine up to 185F or higher. I
had a motor once that was thermally kicking off to save itself and
that thing was HOT!

Hi All,
For those who might find it "interesting" ¨C I noticed the motor of
the HF 8x12-14 was a tad warm and thought a check was in order.
With a motor and ambient temp of 65F the lathe was turned on ¨C no
metal turning. The probe was located on the upper part of the motor
housing, between the motor body and the junction box.
Without noting all of the readings, in the course of:
13 minutes ¨C temp rise 39.3F;
30 minutes ¨C 49.7F;
46 minutes ¨C 58.1F;
63 minutes ¨C 63F ¨C shut-down motor
66 minutes ¨C 65.7F
I didn't run the motor unloaded yet.
So the motor runs hot - an auxiliary fan might be in order.
Take care,
DBN
