Problem finding correct condenser fan motor

I have a Trane XL13i built in 2002. The fan stopped spinning last week but was still humming. If I gave it a boost with a stick at the right time, it would spin right up and run just fine. I replaced the start capacitor and run capacitor. The run capacitor was replaced because it was swelling and two of the wires attached to it had corroded. I also replaced the wires in the process.
The fan blades spin freely when the unit is powered down, but they have significant resistance when the unit tries to kick on. It takes some effort to make them turn. I’m looking at replacement motors and am having issues finding one with the same specs. It’s an Emerson motor, Model K55HXJAE-8958. It claims to have 1/4hp. When I search the model number, every motor that pops up is 1/6hp. I was under the impression that you should never replace a motor with a lower HP one, so I'm a bit confused. Any help would be greatly appreciated. Thanks!

Welcome to the forums.

The manufacturers buy those motors by the thousands and have their own part number put on it.
To properly buy a motor you need the full model number of the condenser off the ID plate.

The upgraded motor based on the old part number is 1/6hp which may be a little light.

Thanks for the help! Here is the label that's on the outside of the condenser unit.

seems it calls for a 1/6HP motor on this label. What would y'all recommend as a good replacement motor?

Geochurchi,
the label on the existing motor had it listed as 1/4HP. My apologies that the photo didn't work for you!

I see data for a capacitor on the motor nameplate. You state you changed two. Were the new ones the same mfd/vac ratings as the ones removed as well as the motor nameplate? Since the motor rotates after assistance starting, I doubt it's the motor windings.

The replacement capacitors had the exact same ratings as the ones that were in the unit to begin with.

Apparently the original OEM part number is still available....K55HXJAE-8958.
1/6hp looks correct.
The new replacement Trane motor is showing 1/8hp which doesn't seem right.

Based on your condensing unit model number the motor listed below is the correct one.
