Re: Mini lathe motor temperature

 

With temperature gauge I can see I needs to run at full speed
It low cost cost item to save from buying a $160.00 motor .

1) I first was think of using a time delay fuse.? The remember thd low speed may not use full ampage.?
2) Next fan sounds great but fan gets block of dies not good.?
3) Then thermal switch ok but motor is And not running.?

I want to before it happens so take it easy or a coffee with lathe running to cool down. I also did find after the motor burn up and is ready for new motor.?

Dave?

Dave, I am wondering.... Have you been running the motor at less than full speed? The cooling on these is typically based on the motor running at full speed so the fan can move enough air to maintain somewhat reasonable cooling. If you find you are running the lathe slower then I would recommend either an increased reduction belt drive (so the motor can run faster whilst keeping the spindle speed lower) and/or a separate cooling fan for the motor.?

On my first heavily modified mini I added a cover to the rear of the motor and attached some light flexible hose (Hoover vac hose) that is attached to a small squirrel cage blower with a bit of filter media on the blower inlet. This keeps the motor cooler and also keeps swarf from being taken in the motor.

Just my thoughts, Cheers
