I got a 1-phase induction motor (230v/50hz) that was taken from a tile cutting saw that I planned to use in a home made disc sander, the labeling on the machine says it's a 600W motor but the motor itself has no information at all on it.
I am doubting that it's 600W because last night as I was truing up the plywood disc by mounting it and using the motor as an improvised lathe. The motor got incredibly hot from running only 5 minutes or so and I stopped to let it cool down, and to considerif this was going to work at all. I don't think I could put that much stress on a 600W motor (.8HP) by spinning a 24cm diameter piece of 12mm plywood.
It also looks smaller than other 600w motors I've seen, I have a 750w 3-phase motor (400V/50hz) that is much larger and heavier, but I do not know how good an indicator size alone is.
I am wondring if there are some simple ways to determine what kind of power range this motor falls into? Perhaps using a power meter and checking the amp draw while the shaft is spinning without any load? Not sure what kind of draw I should be having for a 600W motor though.
