Jim Roadt Posted June 23, 2023 Share Posted June 23, 2023 Just something to move air and keep mosquitoes away. Pulled out of a barn today. Now off to chrome everything. First timer venturing into the post 1950 section Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted June 24, 2023 Share Posted June 24, 2023 1498396176194554773-02792512 (storage.googleapis.com) The motor of the present invention is particularly intended for applications where the lowest possible cost is required, and Where appearance is of somewhat less importance. A skeleton frame construction is well suited for such applications, but conventional low-cost skeleton frame motor designs do not have sufficient accuracy of bearing alignment and air gap concentricity for good performance and quiet operation. Sufficient accuracy can be obtained with these constructions, but only by undesirably increasing the cost. The conventional skeleton constructions, therefore, do not combine low cost and accuracy, and it has always been necessary to sacrifice either one or the other in the design of such motors. Another disadvantage of conventional skeleton frame motors is that they are inherently noisy in operation, since the bearing brackets are drawn tightly against the laminated stator core, thereby increasing the magnetic noise radiated by the motor. The principal object of the present invention is to provide an electric motor of skeleton frame construction which combines low cost and great accuracy of air gap concentricity and bearing alignment. ~ Gustav Koch Westinghouse motor patent description US2792512 filed 1953 1498385916626999123-02628020 (storage.googleapis.com) Quote Link to comment Share on other sites More sharing options...
David Allen Posted June 24, 2023 Share Posted June 24, 2023 Like the blue color; but chrome would definitely look pretty amazing on this one! As for the motor design, it seems that many collectors have experienced motor winding problems on these. Might want to ensure is clean and has an extra coating of insulating varnish on the winding - as well as use an inline fuse to minimize the effects if a failure were to occur.

FWIW...I am not trying to paint the Westinghouse Mobilaire bad. They look cool. Just a heads up to check out your motor condition when you buy one. The hex motor appears to be at the greatest risk based on cost cutting design. 1 Quote Link to comment Share on other sites More sharing options...
Jim Roadt Posted June 25, 2023 Author Share Posted June 25, 2023 How does that switch knob come off? Does not appear to be any set screw in that opening Quote Link to comment Share on other sites More sharing options...
Tony Clayton Posted June 25, 2023 Share Posted June 25, 2023 I would suspect it just pulls off. Its not the original knob. Here's pictures. Quote Link to comment Share on other sites More sharing options...
Jim Roadt Posted June 25, 2023 Author Share Posted June 25, 2023 Thanks I bet they glued it on Quote Link to comment Share on other sites More sharing options...
Tom Zapf Posted June 26, 2023 Share Posted June 26, 2023 IT MIGHT HAVE A SETSCREW ON THE OPPOSITE SIDE OF THE "POINTER" ..PLEASE OIL THAT MOTOR TOO> THE HEX MOTORS WINDINGS CAN COME LOOSE . USE YOUR FAVORITE METHOD TO TIGHTEN THEM BACK UP IN TO THE STATOR. A TOOTHPICK OR TWO ON EACH ONE BEFORE VARNISH DOES A GOOD JOB OF HOLDING THEM IN PLACE Quote Link to comment Share on other sites More sharing options...
Jim Roadt Posted June 26, 2023 Author Share Posted June 26, 2023 It came off with just enough to pry it off and not break it 1 Quote Link to comment Share on other sites More sharing options...
Jim Roadt Posted June 29, 2023 Author Share Posted June 29, 2023 Done ....Baby Blue and fake chrome Hardest part was getting front badge back on , hence the missing screw 1 Quote Link to comment Share on other sites More sharing options...
Arjun Saini Posted June 30, 2023 Share Posted June 30, 2023 I have one of these fans I don’t know if I can trust it’s switch. Quote Link to comment Share on other sites More sharing options...
Stan Adams Posted July 7, 2023 Share Posted July 7, 2023 The hex motor gets a bad wrap, but in my experience it isn’t the motor as much as the switch. Many of these used a Levolier & as soon as it energized high & low at the same time, goodbye motor. 1 Quote Link to comment Share on other sites More sharing options...
