Yes they roll and roll and roll. You learn to let up on the accelerator
earlier when coming up to a light.
My first thought was that I would annoy gassers behind me when I let up
early, but it turns out that the coast down is about the same as the
backing off you do in the ICE, you just don't realize that you are
compensating for the compression brakeing.
I have tried putting my ice in neutral to simulate the feel.

Assuming that you do get a working BLDC controller, (I have no
doubts that you will :) what motor would be available for hobbyists
like us to obtain at a reasonable cost (~$2k) in that 60 to 80Kw
range?

Id like to see an EV sized slip-ring motor. efficiency of ACIM with less
stringent freq control and the starting torque of a series wound dc motor.
but that puts us in the AC department.
Failing that
Adjustable brush rigging. In static mode it allows the user to adjust it
to match the weight of their vehicle and their driving style without
taking things apart. And allows development and later installation of
automatic adjuster.
Larger posts or dual posts , the diameter of the cables is 2 or 3 times
that of the motor post or putting dual cables on sucks.
Integral dual motor,
Real commutators instead of molded comms. Last I checked ordering a
bunch of these would bring the price into an affordable range, but the
market is dwindleing.
Get Rid of the [EMAIL PROTECTED] keyed shaft!
Present a small block chevy crank pattern, after market adapters to
yokes are already available.
Hollow internally splined shaft. Allows you to slide thru and bolt in
and adapter or to stack the motors in a maintainable way.

I've been waiting for a report as well, and I was there. Since John has not
posted yet I can tell you that WZ danced around in the low 12s all night but
never dropped into the 11s. I think it went something like 12.2, 12.1, then a
couple of 12.0 runs. I thought I saw some motor zorch under the car on the
last run I watched and it looked like they were packing up with still a couple
of hours worth of racing left.
And yes John and Rich were in geek buzz heaven playing with charging from the
Plugin Prius. If it were still back in the days of the noisy generators I
would have thought it was pretty cool, but since PIR has lots of free, clean
electricity I didn't really get too excited. Not nearly as excited as the day
when they started plugging in to the grid and could shut down those obnoxious
generators.
This was not a normal night at PIR, as it was part of the Street Warriorz
racing series. http://www.streetwarriorz.com/ The people running the show
had heard of White Zombie and were excited to see it at the track, but that is
the part of the story that you really need to hear from John and I exptect he
will be posting Part 1 some time soon....

Hello All,
I now have been running a interpole motor for over 30 years now. I normally
break it down every 10 years to clean it, replace bearings and may have it
re enamel. Took it to the motor shop to see if it needed any work in the
first ten years and they said they would not even touch it.
The commentator was still glass smooth, no brush marks and the brushes were
only worn down 25 percent. I was told that this GE motor commentator is a
very hard brass alloy which was MICRO MIRROR which is polish to glass smooth
surface. The brushes which are silver graphite are one grade softer then
the commentator. Not too soft or they will wear faster or not too hard of
they will wear the commentator.
Look at them 10 years later and the same story. The brushes were now at 50%
wear and the commentator was not turn at all. It was only polish to a micro
mirror surface. It was turn on a lathe while doing this micro mirror.
At 30 years, I finally replace the brushes with new pre curve silver
graphite brushes that I had in stock for over 30 years. Still have two more
sets in stock. The front of the pair brushes where down to 1/2 inch of the
brush leads and the rear brushes were a bit longer. Clean the motor, run the
motor on the bench with 12 volts, stoning the commentator to seat the
brushes, remove the brushes and rotated the motor with a external motor to
micro mirror the commentator and then put it into surface.
At 34 years, One of the field windings at the rear of the motor which was
one of the loop backs parted. Way back in the 10 year check, I notice this
part of the winding was flatten some, so it lasted that long.
Sent the motor to a GE where they originally built this motor. They
completely remanufacture the motor. In the mean time, I running a spare Warp
9 motor, should have been a Warp 11 and I plan to get a spare Warp 11 motor.
So I will have a Warp 9, maybe a adapter plate and a motor coupler in about
a year from now for anybody that needs one for a C10 pickup or any other
pickup.
Note: This motor and adapter will fit a C10 manual transmission, any other
Chevy 3 speed to 5 speed transmission with a standard Chevy bell housing.
Has the small diameter motor coupler for the later Chevy engines crank
flanges, but also will fit the large flange coupler that you can make for
this motor.
The motor also has a very heavy duty wide clam shell motor mounted with tap
holes on the side to fit any engine mounts. It also has two complete sets
of silver graphite brushes that were purchase from NetGain.

One thing I would seriously consider is your choice of
MCU. I realize it's always easier to use something
that you're familiar with, but the MC9S08DZ60 is not a
motor control MCU. Since you're already familiar with
Freescale product, may want to consider something like
the DSP56F80x family of DSP's. They also have example
code already written for sensored BLDC control,
http://www.freescale.com/files/product/doc/AN1916.pdf?fpsp=1
You can get something running pretty quick using the
sample code and they also have low cost development
boards you can use before laying out your own circuit
board.
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=ECMTREVAL&fpsp=1
I realize your just using the MCU to interface with
the UCC3626 BLDC control IC, but I think you may find
some limitations doing it this way. Overall I think
it's easier to start with a MCU/DSP that is intended
for motor control.
Good luck with either path you choose, and keep us up
to date on your progress.

That's sorta why I said that 'if anyone was interested'... I have
a pair of 25 or 30kW BLDC's so I am doing up the controllers for
my pair of motors. If anyone else has them then great, but if

Please don't get me wrong, I am very interested *and* I also don't
already have a motor. I think that BLDC is really the way to go
except perhaps ACIM as a second choice. I would love to have a BLDC
system in the 40 to 60kw range with regen, etc.
Would those Ford surplus motors work?

How about interpoles?
They would eliminate the need to advance brushes, make regen a bit easier,
and keep arcing down at higher voltages/currents. A little extra
length/diameter/weight would be a small price to pay for a more "bullet
proof" motor. Do interpoles help improve efficiency at all?

I looked up the market price for a new GE 96 volt DC sepex motor, 21HP
continuous rating -- roughly the the same as the old one I'm using.
$5,880 on the GE website. Yikes. Is it really that much more
expensive to make a sepex than an ADC, or Warp series motor of
equivalent rating? Or did I happen to find the MSRP that no one
actually pays or something like that? Or is it the volume of
manufacturing?
And yeah.... haven't been able to find any Zilla level controller for
it yet... :(

That's why I went to rear drive on my 2f1r similar to
the Doran. With a diff in front took all the space needed
for 12 t105's which gives about 100+ mile range. Building
3wheelers must be done right with the CG low and 1/3 inside
the 2 wheel axle or equal weight on each wheel for good
handling.
Done right few cars can beat them for handling. My CG
is several inches below a Corvette's!! Done wrong it's worse
than an SUV!!

-You might look into the Vortex (another hand-built

-I didn't see any on the album. There is an active Vortex
group on Yahoo:
--http://groups.yahoo.com/group/vortex3wheeler/
This is about the best 3wheeler group for all 3wheelers
with as many EV 3wheelers as gas ones with the best advice
on them.
On 8mm belts, # of teeth are 10x dia in inches and the
smallest pulley one should use is 25 teeth primary. 2.5". As
the wheel sprocket needs to be inside the wheel rim so on a
14" wheel, shouldn't be more than 120 teeth, 12" or so which
means 6-1 is rather hard to do unless you have big rims.
Having a sporcket the same or larger than the rim means feq
belt replacement from road damage from curbs, potholes, ect.
I had to give up my favorite EV scooter because of that.
You may want to switch fields to series to get better
hill climbing torque with field weakening to get higher top
end. Would need a new controller though..

I too looked at using the KUEP but couldn't feel comfortable pushing the specs
so tight.
I wound up going with the Potter & Brumfield PRD-11DH0-12. I've seen these
anywhere from $10-$20 in various places.
Its rated for the task. For more than 120VDC you'd need to get the DPDT
version and run serially though both sets of contacts. You'll wind up paying
about $15 for a box/cover for this open frame relay.

Most of these motor are custom assembly according to what the purchaser
wants. They are not off the shelf type. My motor has interpoles with very
large commentators that is rated for a maximum voltage of 250 volts at
ampere over 600 amps. I normally keep the motor ampere at 180 amps at about
50 volts with the Zilla.
So you are talking about double the cost for this type of motor.
For the Zilla to have a regenerative circuits, it would have to have double
the Mosfit modules and two free wheeling diodes at a minimum. A series DC
motor does not have to be reconnected. Additional contactors may be use to
turn on or off the regen circuits.
The battery negative is connected directly to the A1 or armature of the
motor and the F1 or field is connected in parallel with the Mosfits Q1 and a
blocking type free wheel blocking diode D1 as it would in a normal
configuration for a non-regenerative circuit.
Then a second Mosfit Q2 and free wheel diode D2 is also connected to the
motor field F1 and then to the battery.
While Q1 is on and Q2 is off, then you are in the normal run with the
accelerator press or on.
While Q1 is off and Q2 is on, the motor positive line cannot discharge back
through the free wheel diode D2, but now can be discharge through the the
free wheel diode D1 and back through the battery.
This circuit would have additional contactors between the battery and the
controller and a contactor to disconnected the second set of circuits use
for regen if user desire to do so.
This is way my old CableForm controller work.

Michael,
You are busy with your 2SSIC lithium powered XXXX. Just a few quick
questions. I am building a motorcycle using the same DeWalt battery
module that you are using. How many batteries do you use when all the
trays are full? I was shocked to look at your web site and see a
picture of the build with 18 batteries shown. Then later I was able to
see the trays of batteries you use for the street or strip, and that
seemed more realistic.
Do you feel that the batteries stay fairly balanced when you charge? Do
you ever pull them out and use the DeWalt charger for balance? Does
your system use balancers?

Old mature product, nothing left to patent and so can not be used to
attract investors (where the real money is).
They really do not want to have to keep them and parts in stock (but you
will not hear that said outside the smoky back rooms) and so if you want
one they will make you pay.

The Ford surplus motors are ACIM, not BLDC. The power electronics are
the same, but you need different software to control ACIM, and if you
use special-purpose BLDC control circuits (like Dale is), you'll also
need to change those.
I'm interested in building a controller for the surplus Ford motors.
My first project won't fit enough batteries to power one of them, but
in 5 or 10 years, I hope it'll happen.

I thought it was on a thread titled Motor Controllers or some such.

Michael,
Sorry about that. I put XXXX in for the model of your car because I
could not remember it, and did not come back to insert it before
posting. XXXX should be replaced with "1965 Shelby Cobra Daytona Coupe
kit car".

Hey all
Just a quick plug that John and I got to do a little
radio bit today. John drug me into this today on late
notice. Really awesome on many fronts, the first
being we had a lightning storm last night and my power
went out and the alarm clocks went to blink mode, well
that and the fact I was up till almost 2AM.
Picture me waking up to Wayland telling me I've got a
radio bit to do in 45 minutes 8^o I made a mad dash
to the coffee pot to load it up so I could chug it
back down 8^)
I got to plug Killacycles race this Saturday and
hinted at some next project that'll be coming up here
soon 8^) It sounded like it came out pretty cool but
I wasn't listening to it as it played, lol.
They told me they'll send me an file of it so I'll see
if they'll let me put it up at the site as I believe
it was a live show.
Anyway very fun stuff to take part in today 8^)
I'd never heard of the show before today so here's a
link for those who might also not know of it. Of
course comments are welcome so we can show them that
we support their time and energy.
About all the time I have for right now but just had
to share (EVeryone here is tired of hearing about it
already 8^o They did say they'd love to hook back up
in a couple months so I guess they liked what we did
8^)
Thanks for the include on this John 8^D
Hopefully we did EVeryone proud.
Here's a link to their site.
