I have been told the motors I have are rated at 110C (DANG HOT!) but I am building mounts to put small blower under them to direct airflow over them (bfb1012h or bfc1212a) . Either one move a massive amount of air even when restricted thru a filter

Hot Motors Hello all,
I am nearing completion of my JGRO router. I have all three axis running with TurboCNC and only to mount the router.
In the mean time though, I have been trying to tech myself to write G Code. The file I wrote is to cut the cross slide ways pattern out for the Gingery lathe. After about 15 minutes of run time, I aborted the program happy that it was moving where I told it, afterwards I felt the motors with my hands. They were pretty hot, not enough to burn you but hot none the less.
I am running 111 oz-in motors from some Genicom printers I scrapped. They are 200 steps per revolution and I am running them half step.
Any feedback would be greatly appreciated.
Regards,
Joe Hildreth

even if they are hot enough to burn you, they're probably rated much higher. At least 70C, usually up to 100C

I had been told 200°f is what most are rated at, so you shuld not have to worry, and like ger21 mentioned in another thread, you can run them 15-20 x the rated voltage, so lets say you have a 3v motor running at 33vdc then that is only 11x the rated v.
I have made a 30 and 45 minute run with them. They don't seem to be getting any hotter and the performance is fine. Thanks for all the help everyone.
Joe
