This is a drip proof motor from a self serve car wash. It ran the high pressure pumps for the spray wands. I bought it off a guy who rescues stuff like this. I changed to sealed bearings and removed the grease nipples. Bearings are 6206 2NSE and 6203 2NSE. Output shaft is 1 1/8"
This motor is unusual in that when wired for 230 volt operation the capacitors are in series with the start windings. When wired for 115 volts each capacitor and it's winding are in series and parallel to the other start winding. Photo 4 shows the two 115 volt capacitors.
Even with new bearings it runs a bit noisily. Maybe due to the sheet metal internal shroud used to direct air around the windings.
