[JTknives]

well as some of you know im building a nwgs, grinder. i allredy have a disk grinder which is atatched to my 2.5 hp dc motor but my cuestion is should i scrap it and use the motor for my grinder 2x72 or should i get another motor. i found a drill press i can get for 120 it is a jet bench model but the motor has been changed out and i dont think the place selling it knowes that . the motor is a Dayton 3hp 230v 1ph cony duty motor and it looks sealed. but i did not see any case type marking on the tag but some fo the tag looks like it was worn or rubed agenst somthing pointy so the lable is torn off in the corner but not very much. i do have so other info on this motor

FLA 16 (if this is the amps it pulls that does not make sence because thats 3680W and each hp is 746 so that comes to allmost 5hp.

The motor is an ODP compressor motor, an ODP motor would be common on a drill press. Dayton should be rating their motors very close to actual output. Remember that neither AC nor DC motors are 100% efficient, you can probably expect something more like 60 or 70% in a good motor. If you don't try to account for less than 230 volts, 60% efficiency puts the motor just shy of 3HP @ 16amps, I'd say it is rated accurately. The service factor of 1.00 is also a good indicator that you're not getting more than 3HP out of it.

I'd probably not buy it just to salvage the motor, it would probably be a really nice drill press to have though.

I would want a TEFC motor on a grinder, personally. Does this motor have a fan?
