Hybrid alternator as BLDC

https://youtube.com/shorts/pLYTusTA7lk?feature=share
Test is with a 24s battery charged to 87V, I don't know what the rpm is yet because I can't find my tachometer.

Edit: wired to delta for more speed.

Careful when prying the two halves, there is an o ring around the whole case. I used a flat head in the corners and a small hammer.
Once you're past the bearing you can just pull the two halves apart by hand, the magnet force is not that strong.

Any more updates on this? I've got the same setup in a bike I'm building. Interested to see what RPM you saw original vs delta.
 
You need to run this motor at pretty high voltage to get some usable Power out of it (~300v)
With field weaken you can get it to spin almost 10k rpm, it just has very little torque this way and the auto detect values are pretty terrible. I only got it to work somewhat by guessing random values that I got by trial and error.
 
I removed the resolver and installed a encoder, I'm currently using a flipsky and it spins things up on the stand just fine. I did have a heck of a time trying to get it to auto detect with a hall effect setup. I know the PHEV had a voltage of around 270V. I'm planning to try 90v from the current 80v. But I should be able to pack 135v onboard for it. I'm installing it into a dirt bike chassis. Looking at the gearing, I probably need to gear it taller if the motor RPM is going to be limited. Right now it's gear 15/52 and that'd put me at ~50mph at 6500 rpm

What RPM did you see at 87v with and without field weakening?
 
I think I only got around 2k rpm without doing the delta rewire, could be less though. You will want to gear it as short as possible. The flipsky at high phase amps does a very strong jolt and then errors out, this was with encoder.
If you use a hall setup you might get some decent torque in bldc mode.
 
I could never get the flipsky to even complete a revolution in hall effect mode, and that controller has been modded to remove the filters so it's purely a encoder setup now. When I tried hall effect, it would jolt back and forth through detection, cogging and trying to reverse direction. I'm going to move to a MP2 controller next since I need higher voltage capacity and since this unit is only rated for 8.5kw I don't see the need for such a high current capacity unless I want to melt down the windings.

If I geared it 15/39 (39 is the tallest rear sprocket I seem to find for this chassis) and if I could spin the motor to 6850 that would mean 70mph. I just don't want to gear it too tall where I'm working the motor too hard. Probably makes the most sense to get it working as it is current state, then play with field weakening to see where I can get to on that balancing act, then lessen the final ratio and pull back on the field weakening to try to recover some of that lost torque.
 
Interested in your progress. I looked at buying the hyundai HSG a few times but ended up getting a cyclone 6kw motor.
 
I'm upgrading my controller to increase the voltage capacity to run at 135v. I might also try to wire mine into a delta config as well.
