Well I never knew that. Of course GM have been making EXACTLY what I was intending all along.So real life test. For car was trying to turn ac compressor with motorcycle stator as brushless motor. At 24v would only turn about 600rpm with no load. Had stator rewound and rpm increased with no load but once put under load rpm dropped and speed control shut off. This was an 80a speed controll. Stepped upto 60v and started to get rpm back. 72v even better. But basically saying even an ac compressor that takes about 1-3hp to drive wasnt possible.
The only working example of what you want to accomplish is a honda scooter that uses the stator as a starter and generator and the gm hybrids that use a rather large alternator with permanent magnets in the rotor belt driven.
The gm system is 48v and the honda system on scooter is 12v but has a boost converter built in.
Ive tested in real world conditions and its notpossible. You will more than likely find the same.
The gm hybrid alternator would be yourbest bet to start with. Especially cranking a diesel engine.
Motor and Alternator all in one.
Thanks for this lead. I'll do some more reading about this option but looks exactly as I was intending.
Only 3KW continuous however I suspect the 5 minute limit may be much higher with temp monitored shutoff at 80C.
