Mini Mill Harborfrieght

John Meyer All Messages By This Member #70 I have a Harborfrieght Mini Mill and I noticed that the motor and spindle were hot to touch after 25-30 minutes of use in this current warmer summer temperature. My question is, is this a concern? Should I be worried, can it get over heated or is it just normal use? I hope this isn't an extremely dumb question but I just don't want to inadvertently burn out the motor or melt wires. Thank you in advance!?

As long as the motor stays cooler than that it's withing spec. Notes: temperature rise means above ambient.? 40C rise in a 40C room is getting kind of warm the closer to room temperature you can keep the motor, the longer it will last On 6/18/21 10:51 AM, John Meyer wrote: I have a Harborfrieght Mini Mill and I noticed that the motor and spindle were hot to touch after 25-30 minutes of use in this current warmer summer temperature.

davesmith1800 All Messages By This Member #72 The 40°C is hot.? To find the temp you add in the room temperature to 40°C? So room is 30°,C plus 40°C then motor is running at 70°C or 158°F. Dave?
Bill in OKC too All Messages By This Member #73 How hot? That would be kind of important. They will run warm. If you can lay your hand on it, and keep it there, it's probably not too hot. If you can't, it is too hot. You might try aiming a fan at it, and see if that helps. Also blow the dust and dirt out of it, and check the brushes. if they're worn out, it has to work harder, and that will cause it to heat up more than it should. HTH! Bill in OKC William R.

Typically it is over 100°C or 212°F Dave? toggle quoted message Show quoted text On Fri, Jun 18, 2021 at 9:42 AM, Bill in OKC too via groups.io <wmrmeyers@...> wrote: How hot?
