Re: [EVDL] Cheap HubMotors

Are you getting that sort of speed from the C-lyte motors? I'm impressed.

I have older motors (back when warranty was FOB China) and don't get that
sort of speed... though I didn't go above 60V. As I recall, it was about 23
@ 48V and about 26 @ 60V. It didn't seem worth the expense to go with a
higher voltage, and another controller. <g>

I saw one of these rigs when I visited Boston (during the 9-11 "stuff).
There was a restaurant that used one as advertising. I checked into them.
Unfortunately, in Oregon, they are illegal... even if pedaled.

Re: [EVDL] Cheap HubMotors

Hi, your right it is illegal to go above 48V. Though licensing a moped is
very simple. Simply register it as a gas version first and then install
electric motor. You could even use it as a hybrid with a little
modification! I forgot exactly how many volts the brushless motor can take,
but it is supposed to be in the lower 100's. I used to be part of this group
powerassist on yahoo groups or something like that. There was this guy from
scootonthis.com who had done tests on this motor using extreme volts and
couldn't burn it up. I posted some youtube videos along time ago and you can
see them at http://www.youtube.com/ampaynz1 . Basically the 750 watt
brushless motor (called Phoenix now) is a huge metal motor weighing a little
over 20lbs. I installed a 40 amp fuse on it and it never popped, but
controller would current limit to 35amps. If I carried a passenger on the
back and really gave it full throttle, then the 40amp fuse would pop. This
tended to scare the passenger, so I never did this again. Its a great toy
and sure something cool like an electric motorcycle could be made with it if
a higher voltage servo controller is found. I found a 100V 10amp one, but
that isn't powerful enough. Plus, it needs to be DC to trapezoidal three way
AC for simplicity. Using an inverter and converting DC to AC, then to three
way isn't really an option. If not I heard a very long time ago ( little
over a year ago) that crystalyte had an even heavier brushless motor for
sell made for 4 wheelers and someone could special order a 60 amp 72V
controller directly from them.

As far a brushed HUB motors go, the best I have seen can tolerate 48V. If
the inside was solid high temp material and a fan could be installed, then
higher volts could be used. I had bought a wilderness energy motor real
cheap and used it at 60V for a while, but it got as hot as a furnace, so I
put it back to 48V. The inside where the brushes set was plastic and could
easily melt. So I coated the entire assembly with fireproof adhesive. It
made the motor weigh a lot more, but I felt more comfortable then. I think
it went 30mph at 48V. The biggest brushed hub motor for sale I have seen
are the 3000 watt brushed ones from
http://www.electricmotorsport.com/PARTS/EvtSpecs.htm for $750. I believe
they are brushed because I saw them auction off some 1500 watt ones several
time for like $250. These would be easy to use, though speed would limited
by a low voltage. Unless you spoked it somehow and put it on a motorcycle
with a large tire. Then you would just need to find out what kind of
amperage is safe. Basically, so you don't want to overheat it.

It really is only illegal when it goes over legal speed down here in
Florida. It is 20mph speed limit here I believe, maybe 30 in some states. I
once rode 29 miles averaging a speed of 35mph. I kept it at 15amps to go
this distance. Cops can't tell one from another and probably wouldn't even
notice if you were pedalling at a low speed. I had cops yell at me, people
honk at me. Of course I rode it on the highway like a crazy person at night
time using a regular spotlight bulb as a headlight. It was funny when I
would pass a car doing 40. Of course after 9 miles of hot rodding it the
batteries would be at least 50% drained if not more. They'd look at me and
some would be annoyed and some would be interested in what it was. People
would ask me how much it cost and once I told them, then they were no longer
interested from what I could tell.

Re: [EVDL] Cheap HubMotors

That's quite an improvement in the power those motors can handle. As I
recall, mine are rated at 500W, but actually got a bit less than 400... at
least at 48V. They are a lot of fun, when I could keep spokes from warping.
<g>

The illegal part I was referring to is that these rigs are 4 wheels.
Apparently you can't have a 4 wheel vehicle (of that sort) even if it's
pedaled, at least in Oregon. I suppose you could have one if it's motor
operated and can meet the road laws for a motor vehicle.(Sort of defeats the
purpose, eh?)

Of course, that was before low speed vehicles were allowed, so maybe you
could sneak it in under those guidelines. (Still needs fenders, lights,
etc???) I was seriously thinking of buying one for conversion, or just for
pedaling around, until I was hassled for my "powered skateboard" (a scooter)
by the Eugene Police. <g> For some reason, the director of the police
department didn't like those rigs... and it was safer to catch 12 year olds
traveling 8MPH, than it was to stop Free Souls. <g>

How about if you put an antique car body on it, and licensed it as an antique? Many "antique" cars have few, if any original parts by the time the owners have restored and rebuilt them.
