So I’m pretty decent with electric and electronics in a broad sense.. but I’m having trouble with this. I’ve got an old table drill press powered by a 1/3hp, 110vac, 1600rpm, 6.3A motor.
The bearings are free, not binding in any way. The windings are super clean… no obvious over heating damage or corrosion. Powering it up it appears to hit max rpm’s.., it’s pretty quick, but I’m able to stop the rotation with my hand.
It just has no umph.
Motor has a single capacitor.. unknown whether it’s starting or running but it’s only 14uf. Also of note.. inside the casing I found a quad of diodes, so it’s a DC motor behind a rectifier. I find that odd, but maybe it’s more common than I know.
I have not measured voltage before and after that yet. But is it possible it’s just not getting enough dc voltage?
