Hello
Am wondering if someone has had experience with or has built a Variable
Freq. Drive for a brushless AC motor , I have a 1/12 HP motor for a welder
fan , this is a sealed brushless motor that I would like to run at a slower
speed , part of the time it would be at the full 1550 RPM and I would like
to run it about half that speed , motor normally runs on 230 volt , have had
it running for about an hour at 115 volt , does get a little warm , am not
sure if it would last all day at that temp. , lowering voltage is a simple
solution , not very efficient and breaks every rule , I just thought someone
might have been down this road before and could give me a few words of
wisdom , lots of [3] speed motors on the market , most of them have an open
cage that lets all the dirt go inside , or go in the wrong direction , would
really like to keep the motor I already have .
Thanks
Phil
