It could be brushless DC. But i don't know much about those, i think some have 3 leads for the 3 / 6 commutators.

Why is it using such thick gauge wire? An AC 3 phase motor of that size would typically be no greater than 5hp. It's probably drawing 5 FLA. These motors typically ouput a low torque at a slow shaft speed, so that seems pretty useless.

It's hard to judge the size of that motor given the context, but it looks like it might be a Curtis AC50. Here's the spec sheet for that motor:

It makes a respectable amount of torque at 0 RPM, and delivers peak HP at what is probably the point where the engine is running out of airflow.

I'm pretty sure the main function of that motor is providing low rpm torque to help the engine climb to its powerband..
I struggle to see any other explanation for the cog belt setup.
That belt would be unpleasant under load at high rpm.
Or, I could be wrong.
Edit before I am publicly humiliated:
I guess I am wrong.
Timing belts are cog belts and they do just fine at all revs with valvetrain load. And shock. And rapid acceleration.
So there.

My phone takes shitty pictures, but I won $75 in a costume contest today.

I'm interested in what else is going on here though. I see some interesting bracketry and some sort of tube structure in there. The splitter/turnbuckle thing may be idiotic but it's possible they are trolling us and hiding what is really going on there, or at least I hope so.
