Old Westing House Blower Motor

This motor has been kicking around since I can remember. I have no idea how old it is, but if anyone knows send me a message. It is partially enclosed with only vents placed at the bottom of the unit. The only thing I had to do was disassemble if to clean and polish the shaft ends and bearings, add a little oil, and she fired right up!

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

[More350Power]

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

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.

I will be keeping this great WW motor.

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

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.

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...
