Re: [taigtools] How hot is too hot?
- Do you have a link to the motor that you are using (that has a picture and the specs)? I have the standard Taig Marathon AC 110VAC motor and is does not get hot when running under no load. If possible, you might want to measure the AC current draw under no load and see how that compares with the specs for the motor.

Subject: [taigtools] How hot is too hot?
I bought a Taig lathe from Peatol here in the UK a few years ago. To my shame I've only used it a few times since assembling it on a board.
The last time I used the machine I noticed the motor becoming rather warm at the pulley end when removing the belt.
Today I decided to test the motor. I ran it with no load for about 10 minutes during which the time the metal housing had become very hot, using my coffee thermometer (it was at hand!) produced a reading of 55 degrees Celsius (131 F).
Does this sound ok, are high temperatures associated with these types of AC motors?
The model in question is the Elvem 6MY63b4 which is S1 rated.

- I've uploaded a picture of the motor and a shot of the spec. plate.
The motor is the 6MY type - http://www.elvem.it/pdf/monofase.pdf
By the sounds of it there's nothing to worry about, the motor hit 75 degrees C (167F) in use last night but this appears to be within the permissible range.
Thanks for all of your responses,

While it is not a problem, adding an extra cooling fan would not hurt. You are
lucky you got a 230V motor. The recent shipments have been 110V with a
I'm currently investigating an alternative to my own Variable Speed motor

Chinese DC motor options. I need something lighter to complete the installation
of the lathe on the bed of my mill ...
