Chris Jacobsen Posted October 4, 2023 Share Posted October 4, 2023 I have a ceiling fan with the shaded poles that are actually wire wound and connected somehow. I did not open the housing yet but it seems they might be wired up separately. Is this some method of making a shaded pole reversible?

Steve Cunningham Posted October 5, 2023 Share Posted October 5, 2023 Emerson produced one for years. We called them round nose models. Quote Link to comment Share on other sites More sharing options...

I have an older roundnose but not reversible. The shading coils are solid and welded I recall. This one is different but I don't know how the impedance can be changed to make it reverse.

Stan Adams Posted October 8, 2023 Share Posted October 8, 2023 With reversible, there are usually two sets of wires on the shade. One for clockwise and one for counterclockwise. 1 Quote Link to comment Share on other sites More sharing options...

One for clockwise and one for counterclockwise. Right on, Stan. There are two sets of shading coils, and each shading coil is many winds on its respective pole face, instead of the familiar single short-circuited turn. Each pole face has two slots, one on each side. Each set is series'ed together. On one set, the coils are placed to cause a clockwise magnetic shift (rotation),... the other set, CCW. A single-pole double-throw switch will either short-circuit the series of CW shading coils or the CCW shading coils. 1 Quote Link to comment Share on other sites More sharing options...
Derek Warnecke Posted October 12, 2023 Share Posted October 12, 2023 Yep. You should get about an ohm of resistance per set. A two-position SPDT toggle or Levolier selects either the CW or CCW set. Quote Link to comment Share on other sites More sharing options...
Chris Jacobsen Posted October 16, 2023 Author Share Posted October 16, 2023 I have been pretty busy fixing up a house, just got to thos today. Thanks for the input, especially Jim! That was exactly what I was looking for. Now I can open it up and poke around not-so-blindly. I know some of these Diehl fans were reversible, usually levolier switches. Maybe this can even be modified as such since the shaded poles are actually wound. Quote Link to comment Share on other sites More sharing options...
Andrew Block Posted October 17, 2023 Share Posted October 17, 2023 I've never seen a reversible Diehl, only Emerson and Century, but they may be out there. Quote Link to comment Share on other sites More sharing options...
