series parallel
«  »
I have 4 230v ac fans. I hooked them up in parallel and used it to suck the hot air out of the roof window of my house.

worked great, but a little noisey.

so. i connectes them seriea parallel so the motors would run off 115V ac.

but now they almost dont turn... I would expect half speed.

bit strange isnt it... must be the damn bemf?
or could it be the polarity of the fan motors...
