Simple VFD for six 55 watt Single Phase Induction motors


hi

for an art exhibition i need to control the speeds of six domestic floor fans with an arduino which will have some interactivities with the environement

each AC motor run at 220v/50hz/55w and seem to be of permanent split capacitor type

they will be driven each by a separate "channel" of the arduino


after desperatelly scrutining the web during the last weeks for a simple and quick solution i have found that there is aparently none apart possibly from VFDs.


could anyone here please help with some simple to build and not too much expensive circuit that could be driven by 5v from an arduino?


we are thinking maybe to buy several "cheap" VFDs (if that exists...) on ebay but we don't know what type could work for us and we need some advice from experts

would maybe anyone here have some other solution ?

we are are in a hurry to get a solution for this, our time and budget are getting smaller and smaller every day that passes

thankyou very much

you cant run single phase split capacitor motor from a vfd, you need a 3 phase motor or a dc motor with the right vfd

VFD will not work properly for that application. Have you tried a regular fan speed control (phase angle)?

not yet, in the next few days i'll try with phase angle and other moc/triac combinations,

i just was confused with so many people saying phase angle would not work...

so ok, no VFD in my case (slowly learning)

thanks

There's really no such thing as a cheap VFD anyway.
