David Allen Posted December 6, 2022 Share Posted December 6, 2022 Hi folks I was looking on the old forum for patent drawings, or other discussion of the operating principle of the famous Meston desk fan motor. Sadly, there is so much chaff and argument about what is and is not a "real" Meston that the actual info about how the motor works, was lost in the noise. I remember seeing this info previously but cannot seem to locate it now. To clarify, I am looking for a concise explanation of the operating principle of the Meston motor which is not an induction motor. Thanks for any info. I really appreciate it. 1 Quote Link to comment Share on other sites More sharing options...

David Allen Posted December 6, 2022 Author Share Posted December 6, 2022 (edited) Excellent Jim. Much appreciated! Thanks for the links and the picture of the rotor. Would love to see how the commutation mechanism works, as in pictures of the parts. The functional descriptions make sense as to how it works. Just would love to see the actual parts.

Jim Kovar Posted December 6, 2022 Share Posted December 6, 2022 Finch explained the operation of the Meston motor in a much more understandable way, as compared to patent doc. 1 Quote Link to comment Share on other sites More sharing options...
