One thing I have heard about doing this is that you need a little bit ov residual magnetism in the motor for it to work. If you overload it when being used as a genny you can lose that. The solution in this case is to either hook up a 12v battery briefly over one ov the coils or run it as a conventional motor for a short period.
@xanataph Sure, it would be possible. The output would be limited, though. One horsepower is only 746 watts, so a small motor used as a generator wouldn't be able to drive much of a load.
ok, creating voltage is one thing.. but what about amperage? in order to tell just how good the generation is, you need to calculate the watts its producing.. this is done by AMPS * VOLTS = WATTS.. thus known as Watts law. i can produce 10,000 volts with nothing more than a dripping bucket and 2 soup cans.. but amps, thats the work, and the hard part. it takes BIG F'ing coils to make Good AMPS. at 120volts, if you produce 10 amps, your 1200 watts.
@danratsnapnames You're absolutely correct, Dan. This is a work in progress. I wanted to see if I could get it working, and if I could get 120V or so in addition to 240. The next step is to put a load bank on it and see what it does, and that will be another video.
@Possumlivingdotcom i noticed your running a 1756 rpm induction motor as a generator. if your using the 120 line poles then you'll have to double the rpms into it to get 240. but if that motor has a 220v line poles like many of them do, then you could achieve the 220/240 with only 1756 rpms. however, i'm not sure you'll be able to create enough induction to achive any real amps. but who knows.. good luck.
@danratsnapnames There are no 120 line poles. I discuss this in the description. It is 208/220 if wired Delta, and 440 if wired Wye. I have it wired Delta, but there is a neutral line so it makes 220 nominal, plus either 160 or 125 from one leg to neutral, depending on which leg I pull it off of.
This just an experiment anyway, to see what I can do with it. I have a 7.5 KW single-phase generator head I am going to power with this engine.

@xanataph That is true of a regular generator, too. I have overloaded one and had to flash the field to make it start generating again.

That's interesting to know... Something a bit different, do you think that it would be possible to use a little synchronous motor as a generator?

RPM determines frequency... 1765 rpm motor will need to be spun at 1800 for 60 Hz current. Nice work in progress though.

You need a grid-tie inverter and a battery system and you are good to go!

@MrSquirrel2k I have a battery system and an inverter, but not grid-tie. Personally, I have no interest in grid-tie systems.

@Possumlivingdotcom Correction: it is wired Wye-Wye, not Delta.
