I'm back in the hunt for an affordable powerful AC motor. Doesn't look
like anything has changed in the last year or two.
I looked at the AC55 once again, at 300lbs it could or should put out
big power, but their specs are only 310vdc, 56KW peak,
the AC24 is too weak, not cheap either.
The Tesla boasts a 70lb motor that outputs 175KW ?
UQM's motors don't get near that with their biggest motor, which looks
great, but is unaffordable anyway.
What AC motors are they using in the newer forklifts? Available?
What about using AC generators as motors? There are some 10KW available.

Has anyone tried or looked into building a perm mag AC motor?

Jack

FYI there was some investigation into using converted alternators as ac mot=
ors. A larger version for a big truck may get you as high as 10hp.

not sure if you can use it but the B&S Etek brushless DC motor is small
yet potent for its size and while one is probably too little for a car,
2 might do ok.
they cost something like 600$ and weigh 9kg (20lbs)

Yes, that's them. I think they are really good people. Partly because he wa=

the Crux electronics/Synkromotive conversion noted earlier costs $60 to con=

free.

Since the diodes are discarded (I believe) you can easilly use otherwise de=

So it seems nothing has changed over the last two
years, still no affordable powerful AC motors out
there or controllers, at least the EVDL list knows
about. A go-cart motor is cool, but isn't much help
for a full-size car.

I have two of these motors (Mars Electric), one in my
jetski with a 48v-200amp controller I built, the 120v
version is still not working. =


But that is still not powerful enough for a car, or at
least a fast normal car. I've considered ganging them

I'm still relatively new to motor theory but as I see it the voltage
limit in an AC motor (brushless DC) is not a wiring issue but one of max
rpm the motor can mechanically handle. a wire doesn't have a voltage
limit (except for maybe insulation but maybe that's not an issue in
practice)

maybe someone else knows, am I right that voltage for an AC motor is
only limited by the the rpm it can handle? (assuming current limitation
of course)

further, as I've stated before, why not look into what motors the
several available hybrids use today? once in a consumer mass production
environment the prices tend to be much more reasonable. I was at a car
show the other day where I saw the very nice Lexus LS600h which although
still a mainly gas hybrid, the salesman claimed 530Nm torque on the
electric motors alone. sure a lexus part could be expensive but maybe
someone could look into spare parts cost of some of the more mainstream
SUV hybrids in USA. some specs and a price. would it kill someone is USA
to do that? : )
is it an EV developers list or a rest home

: ) if a little provocation gets the job done I'm not above it.
but please give them a call for the parts. it sounds like there are at
least motor but probably more. they might be expensive but then at least
we'll know where we stand and don't waste more time hoping in that
direction. we might be positively surprised.
as for the botton I think that's actually a good thing, maybe it gets
them hooked on the good stuff until they scream for more :)
although hybrids are not really efficient it's a great way to expose
electric drive.
the EV grin is more addictive than crack :)
