I posted about this motor a couple of days ago, and wanted to follow up in another direction. The motor in question is 1-hp Craftsman motor from a table saw and is about 45 years old. After rewiring it for 220 volt service, it started a few times and now doesn't want to. When completely cold, it starts fine, but after running for a few minutes (no load) it warms up a bit and then will not restart. When power is applied, it rotates backward slowly.
This motor is labelled "1 Horsepower Capacitor Motor" and also "Ball Bearing". I assume that the bearings are pretty good, because it takes 70 seconds to spin to a stop after power is turned removed (yeah, I timed it). More importantly, it apparently has a capacitor for starting, but I don't see it anywhere. There is no external capacitor housing or cover like I'm used to seeing on more modern motors. Could it be inside the frame? I hesitate to take it apart just to see. Also, I assume that this a brushless motor since it's gone nearly a half century without replacements.
Can anyone tell me more about this motor and/or direct me to a site with such information? TIA.
