I am new to this forum. I offered to rewire a 1957 Westinghouse Riviera fan for a friend. It is turning into a complete motor rewind. It has 5 wires going from the 2 speed switch to the motor but, since the windings are bad, I can't use a meter to figure out the connections inside the motor. I think I could use just 3 wires to accomplish the same thing they did with 5. One wire would put AC on 4 coils in series (High speed). One wire would put AC on 6 coils in series (Low Speed) and one wire for return. Does anyone have any better ideas?

WHAT SIZE IS YOUR RIVIERA? THEY CAME 8 AND 10" (3 BLADE) AND THE LARGE 16" (FOUR BLADE) AND 17" (THREE BLADE AGAIN) ...IT WILL PINPOINT THE MOTOR FOR ADVISORS HERE

It is the 17 inch 3 blade with the hexagonal shaded pole motor.

WAS IT A SHORT PULL CHAIN LEVOLIER SWITCH?

It has a two speed rotating switch that starts at Off and rotates clockwise to High then Low. It is made by Bryant and it is a model Y-50191 15amp 1/2 H.P. 120-240v switch. It has male spade connections labeled 1 through 4 plus a 120v Line in connector. It also has another pair of connections that jumper together to other side of the 120v Line in to a wire going to the motor. On High speed, the Line voltage is applied to spades 1 & 4. On High speed, connections 2 & 3 are shorted together. On Low speed, Line voltage is applied to pin 4 only. On Low speed, connections 1 & 3 are shorted together.

Actually, I think the wire I am calling #1 is actually #5. The paint is smudged on my switch. I found a schematic for a Mobileaire that looks a lot like mine. I was assuming the 2 speeds were due to changing in the number of poles but it looks like it is just a change in impedence by running through longer coils. At least that's the way I read the post at http://www.afcaforum.com/view_topic.php?id=52651&forum_id=5&highlight=+westinghouse+hex. Please let me know if I am reading this correctly.

It looks as if you have struck gold by finding that link. That is a variation of a tapped winding shaded pole. It should not be terribly difficult to rewind, if you are careful about the wire size and turns count of each winding. There is a possibility that the motor is wound with the skein technique, where each winding is a large coil weaved around the poles. That could be more challenging.

I did more digging (literally in my shop trash) and verified that the 3ohm coil sets are 200 wraps x 2 coils of 22 ga wire and the 5ohm coil set is 200 wraps x 2 coils of 24 ga wire so there is no tap out of the center of any coil. I am finishing an updated schematic and a physical drawing of the actual windings and connections. I am also picking up another hex motor fan today to verify the location of each coil set. As soon as I can find the original post, I want to give credit to the member who posted the hand drawn schematic. It really helped.

Very nice. It looks as if you may have done this before!  Now, how does it run?

So quiet. Only draws 2.5 amps on high and motor frame only gets to 100 degrees Fahrenheit. My wraps may not be quite as tight as the factory so my DC resistance was an ohm or two higher but that may be better from a heat standpoint. Used a camber vacuum and ATF to re-oil the bearings and felts. So much easier than heating on the stove. Low speed seems very slow but moves a lot of air. I should have put a tach on it to test before I gave it back to it's owner. She was thrilled.

Hook everything up the way shown and you're done. BTW, this IS as complete a wiring diagram as you will ever find for the fans this applies to.

I had 3 of those & all of the motors failed, so I stopped getting those later westy fans, nice work - what kind of number would you put on that rewind?

James Perkins wrote: You actually rewound a hex motor? I have a few questions. If those hex motors have 3 sets of windings, was each individual set wound on certain posts, or did you wind all 3 sets on all 6 posts? Did each set have different size wire, or were all 3 sets 24 gauge wire? Also, I assume you used all 5 wires in the stator line for the reconnection?
