Can a capicitor start AC motor be used as a generator?
I'm trying to build a homemade wind generator and I'm having all kinds of trouble...I know DC motors are the easiest to work with but AC motors are the easiest to come by, at least they have been for me thus far. I have tried multiple motors some with capacitor start and a couple without. All I get out of any of them is NOTHING! LOL It's so irritating. I have a full wave diode to convert the AC to DC and I have tried all the motors both with and without the diode and that max I can get out of them is something like .02 VDC or AC it doesn't matter what I do I still get the same results. I know the meter is fine cause I have used it on little hobby motors and it read their voltage just fine. The motors do work I've plugged them in before and they run fine. Any ideas on what I'm doing wrong and thing I should try would be greatly appreciated. I'm not sure if the motor with capacitor start is a usable type for what I'm trying to do. Just came across a website a while bck that said yes Thnx

I do not understand what you are doing. if a wind generator is to be made, then the wind turbines should rotate and this rotation should be coupled to the generators and the generator will generate voltage and if sufficient voltage is generated (In US it is 110 V AC) and if the have the capacity to have enough power then they will run your AC motors or if you DC motors then the voltage and power generated should be equal or more than the motor's driving power. If you do not generate any power/voltage or produce very little power then the motor will not run and will load on the generator and the voltage will go down to zero.
Are you connecting the motor as generators and coupling them to the wind generator? then I very much doubt whether they work. If they are synchronous motors, then they can run as generators and vice versa.
So everything properly and consult an electrical engineer. There is a chance that you may get electrocuted.
