I have a White Westinghouse 1/4 hp motor, split phase. My motor plate is kind of similar look, it is also showing the 1725 rpm, 5.6 amps, and my motor says it could have been built in 1942, 1943, 1951 or 1956. So your motor could have perhaps been built up during these years ? It sounds the same as mine, however I did put a ON/OFF switch on a special switch box to replace the plate. When my motor starts, it does make the lights flicking a little.
Variations on this theme are the capacitor-run (also called psc or permanent split-capacitor) motor, which uses an oil-filled capacitor in series with the start winding (usually called the auxiliary winding) and which is always on-no start switch. Many furnace blowers now use this type of motor. Not quite as much start torque, but very efficient. The capacitor start-capacitor run motor combines both types, and has a start switch.
@Friendoffreedom Thank you for the information, appreciate it! Those are the motors they use on the direct drive blowers in most furnaces now, if im not mistaken.
This is a Westinghouse split-phase motor made in the middle to late 1950's. The difference between this and a capacitor-start motor is that the latter has an electrolytic capacitor in series with the start winding. Depending on the resistance and no. of turns on the start winding and the degree of capacitance, the capacitor can 1) reduce the starting current considerably, and 2) if so designed, can considerably increase the starting torque.
@Friendoffreedom That would explain the 1/4 capacitor start that I use as a bench wire wheel buffer kicks right on. Thanks, always appreciate comments and additional information!!
I wonder if A.O. Smith is usa? I had an old dayton motor replaced it with another dayton and was pissed when I saw mexico on it. I have a couple marathon motors. Thanks for the list, appreciate it! I had a GE that said assembled in mexico, dont know if thats all of them though.
I saw one of those marathon motors when I was changing blower bearings on an OLD oil furnace. It ran perfect, but the furnace being 40 years old or so, was in bad shape and got replaced. I have the burner from it on a video on my channel. Didnt get a chance to grab the old motor, I did get a newer marathon motor though. I made a power wire wheel out of a dayton motor using a drive arbor attachment that I cant find anymore. The best thing I ever put together! Thanks for the comment!
I'd say it's older than the 60's. I have a Marathon brand blower motor that came out of the original furnace in my parents house. It looks newer than this one, and their house was built in 1957. I'd guess it's from the 40's or 50's. I made a power wire wheel out of mine ;-)
It might have been. If it was ever used before I got it, I doubt it. There were no wear marks on the pulley and it didnt look like it was ever wired up. It sat in the corner behind the old furnace for years. It would have worked on the old fucnace, rotation is wrong direction and cant be changed.

I will be keeping this great WW motor.

I guess this is a split phase motor, is it better than a capacitor run motor?

@sayrocknoanime I believe this is a split phase. It uses more amps on startup than one with a capacitor assist. Thanks!

i had a much newer WestingHouse Motor, but the bearings failed, so i burnt it up. xDD

A lot of motors used in the USA are made in the USA. Here they are:
Leeson
GE
Baldor
Marathon
Bodine
Reliance
Imperial Electric
Advance DC
Too bad Emerson and Dayton no longer make it to this list since now they have their motors assembled in Mexico...

definently an early 60's motor!
