Anthony Lindsey Posted April 17, 2022 Share Posted April 17, 2022 Picked this up. 75431 instead of the usual 75432. Also has a stamped circle in the Cycles box along with 40 1 Quote Link to comment Share on other sites More sharing options...
Stan Adams Posted April 18, 2022 Share Posted April 18, 2022 I used to have one of those. John McComas experimented with one & found it ran good on a half wave rectifier. Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted April 18, 2022 Author Share Posted April 18, 2022 I will play with it. Any idea what the stamped Circle is in the Cycles box? The 4 was stamped over/inside the circle. Quote Link to comment Share on other sites More sharing options...
Stan Adams Posted April 19, 2022 Share Posted April 19, 2022 I don't, don't think mine had that. Quote Link to comment Share on other sites More sharing options...
Steve Rockwell Posted April 19, 2022 Share Posted April 19, 2022 Quote "75431 instead of the usual 75432." I know nothing of a 75432 being offered, excepting the single image above... typo? What about spec. number? Info is incomplete... Assuming the rest of the tag reads like the lower image above i.e. Type AOU, then the 40 has likely not been altered to indicate DC application... "DC" stamped in the "cycles" field is what's customary... The motor frame for the DC fans is, naturally, identical to yours... I'd guess the circle is to highlight the 40-cycle specification for best running conditions..... Quote Link to comment Share on other sites More sharing options...
Steve Stephens Posted April 19, 2022 Share Posted April 19, 2022 That circled part is iron and magnetic on my Form AB, 1923 GE AOU. Also, the brass bell oscillator disc was always painted with the same paint as on the fan. Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted April 19, 2022 Author Share Posted April 19, 2022 I will be back to that fan on Friday, will report back on if that is a brass collar and take picture of other side of tag. Quote Link to comment Share on other sites More sharing options...
Steve Rockwell Posted April 20, 2022 Share Posted April 20, 2022 I can't explain away my assumption your fan is 12-inch... a little Old Forum search turned up the correct answer: https://www.afcaforum.com/view_topic.php?id=35267 Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted April 20, 2022 Author Share Posted April 20, 2022 It is 12". Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted April 22, 2022 Author Share Posted April 22, 2022 The neck is steel or cast iron. Looks gold in the photo but it's the light. Magnet sticks to it. Darn.😒 Quote Link to comment Share on other sites More sharing options...
