One of them was NOT that you are a very nice and helpful guy and the other one is a bit of of a follower of a greenwashed, self centered pathetic coward hell bent on pushing his own agendas, admin..... but is into electronics and DIY power.
I put the knife into the said greenwashed Admin yesterday by recommending this site and doing a long post extolling the Virtues of generators running on waste oil to a guy asking about off grid setups.
I have heard the urban legend of an induction motor as generator for years, I have a little pamphlet from lindseys bookstore entitled "alternator secrets" I bought in the 90's. I also used info from this link http://www.redrok.com/cimtext.pdf. well I set up a nice 3 phase 5hp 1725rpm motor coupled to the little 4hp lister LR1 I bought over the winter. made a nice base and used the doghouse from my ST head that I removed. wired it up in Star and it did nothing. waited for caps to come in the mail and added (3) 25uF caps in delta on the 3 legs and still nothing. Flashed the field and nothing. I wanted to use Star with the center connection as the neutral. Just for kicks I rewired the motor in delta and hooked up the caps. started it up and the light on the doghouse lit right up. I thought that was cool so without a second thought I throttled her up to 1800 rpm and boom boom out go the lights followed by one of the caps being on fire. shut it down and then in put the 20uf caps I bought as backups on and tried again. this time just idling It maks about 150 volts and if you give it any rpms the voltage goes way over the scale of the meter. what is the deal? you supposed to add load and caps a little at a time as you load the motor as a generator? any body got experience with this? pics to follow if anybody is interested.
The project I'd like to see is the inverse of this one; turn the ST-3 or ST-5 into a starter motor, which will then got back to being an alternator.
...but now I have to find something else to do with this little engine.
