Help!

It's a capacitive-start AC motor. Here's a photo of the wires & connector: Here's a photo of the connector with the DC resistance I measured across the various terminal combinations: ...and here's a photo of the only identification on the fan: The fan came from a range hood blower. This fan was one of two., the other motor has a broken internal support. As I read the label, it says Elica, which seems to be a maker of range hoods made in Italy. I searched for "Elica schematic", "Elica wiring", "Elica diagram", but wasn't able to find any helpful info. Any ideas? -AC_Hacker ? ? ? |

Brushless DC Motor Control using ATmega32M1
Quite by accident, I came across this app note: Brushless DC Motor Control using ATmega32M1 Looks like the ATmega32M1 is similar to the processor used by the Arduino community plus a Power Stage Controller. -AC_Hacker |

Sorry AC Hacker, I'm not familiar with US wiring, so I wouldn't want to speculate on how to wire it up correctly. I'm also not really a power EE, and haven't done anything in that area since university anyway. I'd be just googling the same as you.

There is some stuff around on the web.. Is there a switch in that fan unit?
One that opens, when the fan motor starts running? I had one of those flying balls centrifugal gizmos on an old oil burner motor once. It broke one night at 3AM.. I drilled two small holes in some spring thing that held one of the weights and tied them together with a paper clip.. It worked for years, until the system was replaced..

Hi,
i am new to this great group and i would like to thank you all for your contributions and thoughtful work. also i did not find the usual off topic sliding on private or ego issues thank you Dave Meinert for sharing your work and showing us that this is feasable and working. i am going to start building these weeks and would like to ask if any of the "plastic " versions have been finished and are working? is there anyone who tried the metal version in comparison? also, did someone experiment with the old AC/dehumidifiers (the surface is great, but just not even for both streams, due to the water-air mechanism )? thank you very much for your help laderload |
