If you have your heart set on a belt/pulley arrangement, you'll need a
toothed (synchronous) belt. The Gates Polychain seems to be the belt of
choice. I don't think they sell online, but they do have downloadable
catalogs, and charts for selecting the proper belt that would replace an
equivalent roller chain.
http://www.gates.com/brochure.cfm?brochure=2813&location_id=742
Chains are still cheaper for initial purchase, but they're noisier, need
lubrication and adjustment.

G'day All, especially Jim Husted
Latest motor that I'm playing with - have had it on the shelf for a
few years, but now may be its' time. Certainly its' time to be played
with, anyway. Photos start on:
http://jcmassey.gallery.netspace.net.au/Daihatsu-pics-01?page=4
It's reputed to be a floor sweeper motor, 36V, possibly from a
"Tennant" (brand) sweeper. From what I can make off the lable it is a
prestolite, and that's it! 14" overall in the body, around 7-1/2"
diameter, 9" long in the field tube.
It is compound wound, and is (was) set to only go one way. I'm
planning to extract seperately the series and shunt fields, and the
brush connections. If the trike ever gets built, this motor may be
able to do that (pulley drive to the diff input shaft), but at the
moment, break times will see this motor getting a birthday.
The plan for all this access is: reverse (reversed armature, 36V on
shunt field), boosted-torque low (overdriven shunt field), low (around
36V on the field), med (maybe 15 to 20V on the field) and high (no
shunt field).
Control is planned to be in part controlled via a little PLC or
similar, allowing certain things at certain revs (and rev limiting),
select up/down via paddles on the handlebars(?maybe). Make a little
PWM controller for the field. 72V system since I have plenty of 72V
contactors and a complete 72V GE-EV1 SCR controller system.
So, Jim, what am I likely to get from this motor used like this? Of
course, everyone else is aencouraged to 'voice' their opinion, too.

Thanks Jude for offering a non-torrent method to download the mp4.
Downloading 132mb via a skinny modem using torrent would have been
painful. While my work connectivity has excellent bandwidth (a T2
line), their firewall does not allow torrent downloads.
The server you are using is offering a 80 Kb/sec transfer rate and
I am 50% done with the download.
Thanks again.

How corruption & greed led U.S. from electric transportation)
[The Internet Electric Vehicle List News. For Public EV

Oil Junkies
How corruption and greed led America from green electric
trolleys to polluting, petroleum-powered automobilesand what we
can do now.
i
Edwin Black is the author of IBM and the Holocaust, which in 2003
won the top two awards of the American Society of Journalists and
Authors for best book and best investigative article; and of
three other books, including War Against the Weak: Eugenics and
America's Campaign to Create a Master Race.
His most recent book is Internal Combustion: How Corporations and
Governments Addicted the World to Oil and Derailed the
Alternatives, from which the following is drawn. He was
interviewed by Reform Judaism editor Aron Hirt-Manheimer.
i
According to your book, there was a time in America when we as a
nation were not dependent on oil to power our cars.
Yes. In the 1890s, most of the original automobiles were
smooth-running, quiet, environmentally friendly electric vehicles
powered by lead batteries. Thousands of such vehicles traversed
our city streets and even the back roads of rural America. How we
regressed from electric to oil is a complex story rooted in
corruption and control.
Here's the short version: During the first years of the 20th
century, the electric vehicle people were "the bad guys" in
America. The key players were the Pope Manufacturing Company in
Hartford
[ http://en.wikipedia.org/wiki/Pope_Manufacturing_Company ]
--which had secured a monopoly on the bicycle industry;
the Electric Vehicle Company in New York and Philadelphia
[ http://www.bruceduffie.com/1903.html ], which controlled a
monopoly on batteries; and a small group of powerful carmakers
such as Olds and Packard.
Together, they created an automobile cartel that tried to dictate
who could and could not buy and sell a car in America--and what
kind of car. These monopolists acquired a primitive automobile
patent called the "Selden Patent,"
[ http://en.wikipedia.org/wiki/George_B._Selden ] designed from
the outset to be used as a patent litigation weapon.
Armed with this patent, the cartel threatened to file an
expensive patent infringement case and injunction against every
American who purchased an inexpensive internal combustion car
that the "Selden Trust" did not authorize. At the same time,
the cartel allowed its own technologically superior electric
vehicles to falter in the marketplace in favor of high-priced,
extremely profitable gasoline-burning cars designed for the
moneyed elite.
Remember, this was before mass production; each car was
hand-built. Oil, especially oil from the Mideast, was very
cheap, much cheaper than a lead battery. What's more, supply
and demand of oil could be manipulated, yielding
billion-dollar profits.
Soon, production of electric vehicles became limited to a few
dozen small, independent car companies that could barely keep
the flame of clean auto-making alive.
Didn't Henry Ford play a major role in popularizing internal
combustion automobiles?
Yes, but that's only the end of the story. The beginning is
fascinating. In 1903, Ford introduced a cheap, mass-produced
internal combustion machine for the average man that
revolutionized the car industry. The Model T became the
"everyman" car. [ http://en.wikipedia.org/wiki/Ford_Model_T ]
This was also a time when electric vehicles and battery
makers--even decent independent ones--were perceived by the
masses as scoundrels, crooks, and liars.
For decades, imperfect, broken electric-battery technology had
been used by devious financiers to launch stock swindles and
monopolistic trusts based on exaggerated technology and
capability. Thus, for many Americans, purchasing a Model T
petroleum car over an electric car became an act of popular
defiance against the rich, powerful, and corrupt transportation
tycoons who were attempting to control the people's freedom of
choice and movement.
In 1914, however, Ford saw the light, so to speak, and joined his
lifelong idol Thomas Edison in a project to replace gas-driven
internal combustion machines with cheap electric cars powered by
revolutionary lightweight nickel batteries that could power a car
or truck about 75 miles on a single charge and last for 40,000
miles--which could be the life of the vehicle in those days. Ford
and Edison envisioned that all home and automotive energy would
eventually be generated by wind-powered backyard and basement
generators.
Together, the two men invested years and millions of dollars to
perfect a new generation of battery-run vehicles and to create a
national infrastructure of charging stations and even curbside
charging hydrants--remember, this was before gas stations were
even invented. Their creative research and planning coalesced in
1914, when they were ready to launch mass production. America
once again stood at the crossroads. Would we drive vehicles
powered by electricity or oil?
Obviously oil triumphed. What happened?
The Ford-Edison electric vehicle was mysteriously subverted by an
inexplicable and suspect series of events. Edison's batteries
worked perfectly in Orange, New Jersey when Edison shipped
them--yet when they were tested at Ford's facilities in Detroit,
they inexplicably failed to work.
Before Edison could recover, his laboratory and facilities were
struck by a mysterious flash fire that burned everything. Ford
eventually abandoned the project. The story is heart-breaking. I
call 1914 the beginning of the end of clean electric in this
country.
Yet at the time, much of America's mass transit ran on
electricity. What happened to those systems?
In the 1930s and '40s, General Motors, the Firestone Tire
Company, Mack Truck, Phillips Petroleum, and Standard Oil of
California--all operating through a front company called National
City Lines (NCL)--bought up dozens of local mass-transit systems
that were operating the popular electric streetcars. Their plan
was to control virtually all the leading mass-transit systems in
America, and replace electric trolleys with smoky, gas-guzzling
buses.
[ http://en.wikipedia.org/wiki/General_Motors_streetcar_conspiracy
]
In many cases, these trolley transit companies had previously
been financially looted by their financier owners and fallen into
disrepair, which only made them easier targets for acquisition.
Once NCL purchased the trolley lines with "borrowed" money from
GM and others, the tracks were torn up and the trolleys sold or
destroyed, replaced by petroleum-powered GM buses running on
tires and oil supplied by the NCL companies.
NCL started with small cities in Illinois and Texas. Within
several years, the company managed to devastate or destroy the
trolley systems in some 40 cities, including Baltimore, Tampa,
Los Angeles, Oakland, and Salt Lake City. Then, in the years that
followed, the badly managed NCL bus companies disappeared as
well, leaving no mass transit and, in many cases, no alternative
means of transportation other than individual automobiles.
How could such a scam go undetected for so long?
GM and its conspirators operated through National City Lines and
numerous other Enronesque subsidiaries and affiliates,
substantially under the radar. Yet once the NCL conspirators
seized a transit system, so many citizens complained that
ultimately the FBI launched a massive nationwide investigation to
connect the dots.
It began October 2, 1946 when the Department of Justice sent a
memo to J. Edgar Hoover regarding "numerous complaints concerning
the activities of National City Lines, Inc., and various
associated companies in connection with the acquisition and
operation of local transit systems acquired by those companies in
various cities throughout the country. Through a series of
contracts, manufacturers of buses, tires, and petroleum products
have become important stockholders in the National City Lines.
Investigation of the complaints disclosed the probable existence
of a systematic campaign by National City Lines, acting with its
manufacturing stockholders, to secure control over local
transportation
Then what happened?
FBI agents in blue suits fanned out across America interviewing
executives, transit experts, community leaders, and local
officials. Subpoenas for masses of documents were served. On
April 9, 1947, NCL, GM, Mack Truck, Firestone, Phillips
Petroleum, Standard Oil of California, and a group of their key
executives were indicted by a federal grand jury for conspiracy
to monopolize.
Count 1 alleged a conspiracy to control mass transit through
systematic acquisition and in so doing exclude all competition
for motor buses, including electric trolleys. Count 2 alleged a
"conspiracy to monopolize" the bus business by creating a network
of transit companies that were forbidden to "use products other
than the products sold by supplier defendants."
This was a first-of-its-kind prosecution--the first antitrust
action against companies that were using exclusivity contracts
and "required purchase" contracts in another industry,
effectively creating a monopoly. All of the defendants were found
not guilty on the first count, and guilty on the second. On April
1, 1949 the judge handed do
By the time of the guilty verdict, GM, Firestone Tires, Mack
Truck, Phillips Petroleum, and Standard Oil had succeeded in
irrevocably changing mass transit in America--42 cities in 16
states were converted from trolley to motor bus--a trend that
ultimately converted our country from clean, electric
transportation systems to polluting petroleum-powered buses.
America has never recovered.
In your book you also point to the business connections of GM and
Germany during the Hitler years.

So supersurface area is the difference.
Sort of. But almost all capacitors (and batteries) do the same thing, to
various degrees.
Two nice smooth metal surfaces only have an obvious amount of surface
area; 2 square inches for every 1" x 1" piece (top and bottom). This
would give you a tiny capacitance (or tiny amphour capacity in a
battery). But roughen up the surface somehow, and the surface area goes
up. It's usually done by chemical etching, or by mixing two materials
and then dissolving one of them away to leave a sponge-like structure.
You can have a total surface area that is thousands or even millions of
times greater that its physical size.
But capacitance (and internal resistance) is also controlled by how
close you can get the two plates together. Roughening the plate surfaces
makes it hard to get them close. So, they generally chemically etch the
surface of the plates to coat them with some very thin insulating
material (a few millionths of an inch thick). In a capacitor, this
coating is your dielectric (like aluminum oxide in an aluminum
electrolytic capacitor). In a battery, it's your active material (like
lead oxide a lead-acid battery).
Then, you put some conductive filler between the roughened coated plates
to fill in the gaps between the two plates. This is the "electrolyte".
Current flows from the outside terminal to one metal plate, through the
thin coating on the plate, the electrolyte, the thin coating on the
other plate, and the other plate to the outside terminal. This is where
the "double layer" name comes in.
All this is old, well-know technology; no magic solutions. The rougher
the plate, the greater the capacitance -- but the harder it is to make,
and the harder it is to *keep* that microporous structure from plugging
up. The thinner the insulating layer, the higher the capacitance -- but
the lower its breakdown voltage will be, and the easier it is to fail
shorted.

Just add a 12v zener diode in series with the battery lead to it. This
will drop all its reading by 12v, putting you back where you started.
This is a ten cent part.
By the way just how accurate would that be?
The original wasn't very accurate. It is basically just an
expanded-scale voltmeter, marked in percent of charge.

It could be as simple as making a voltage divider from 2 resistors to
divide the 108V back down to 96V before it is applied to the black box
that drives the SOC guage.
You would need something like the following:
108V
|
/
\ R2
/
|
+----- 96V to SOC box
|
/
\ R1
/
|
0V (pack -ve)
Where R1 = 8 * R2
Using 1% resistors, you can get pretty close using R1=21.5K and
R2=2.67K. There will be about 6mA worst case flowing through the
divider, so R1 would need to be 1W or better while R2 need only be 1/4W
or better.
Depending on how much current the SOC box draws, the accuracy of this
approach will be degraded. A better approach is to use a single
resistor in series between the 108V pack and the SOC box voltage input,
with the resistance chosen to result in 8/9ths of the battery voltage at
the SOC box input. It would probably be good insurance to add a 130V
zener diode from the SOC box input to ground just to make sure it
doesn't see voltages beyond what it might have been designed to handle.
Alternatively, increase your pack up to 120V and buy the SOC box from
someone who has upgraded their 120V Jet 007 to an E-meter setup ;^>
> By the way just how accurate would that be?
Not very, unfortuantely.

Roger.

Add radial tires and 60 years-worth of aerodynamic improvements,

classified as a motorcycle but carrying 3 people would have made the
Sparrow much more marketable; using this 3-seater's design, even if a

Mike Young brought his Solectria EV to Utica, NY Munson Williams Proctor Art

I stayed after the performance and handed out literature and answered
questions. In fact, last Wednesday afternoon, September 13 Mike Young was
interviewed by the local NBC television station, WKTV and this story was aired
during the 5 PM news that afternoon.

I have one frustration I was not sure how to handle properly while answering
questions and promoting EV's: When I was asked, "So where can I buy one" I had
difficulty answering that question satisfactorily as there are few if any
manufacturers of EV's available to the general public.
Suffice to say, there was a modest turn out at these showings of WKTEC

Lee,
Regarding the capacitor to the antenna. Which end to I hook to the antenna
and which to the capacitor?
Would it be antenna to + on capacitor and - on capacitor to earth ground or
use the actual signal cables to attach to the capacitor.
Also, would any capacitor work, or does it have to meet a specified
voltage?
Thanks, Ben

Thanks for the great news clip. I like answering that question. Nothing
piques someones interest like telling them they can't buy one :-)
I wonder if anyone has a handle on how many local news crews are doing these
stories these days. I know the older timers must have been ecstatic when A
single news story ran on the local news. Now I bet one runs in at least one
town around the world EVery day. I wish we could collect them all:-)
Since the newspaper article yesterday I'm getting calls from all the car clubs
to display at next years shows. EVeryon'e news coverage is catching on pretty
well.
Mike,
Anchorage, Ak.

I just saw an advertisement for a new system for inductive power
transfer. It's called "Movitrans" by SEW Eurodrive
<www.seweurodrive.com>. It's intended to transfer up to 3kw of power to
one or more devices in a factory without any wires attaching them.
There is a power unit that plugs into AC power; they have 4kw and 10kw
sizes. It converts 240vac 60hz into 25khz low-voltage, high-current
sinewave AC.
Then you run a pair of #2 wires, spaced well apart (like a railroad
track), around the area to be covered.
The "pickup heads" are basically 25khz power transformers, that pick up
the magnetic field from these wires, and rectify it to provide DC power
for motors, equipment, or whatever. Pickup heads are available for up to
3kw of power. They can be spaced up to 20 mm from the wires (almost an
inch), which allows a fair amount of design latitude.

No:
<http://www.rsportscars.com/eng/cars/venturi_fetish.asp>
Lists the Fetish at US$664,000 (540,000 euro)
Venturi's own site lists the Fetish at a slightly more economic price of
450,000 euro (US$570,000):

I suspect you are confusing the Fetish with the US$100k Tesla Roadster.

Hi there,
hoping that Jim or somebody else knowledgeable with EV motors can give me
some hints here. I wonder how high I could crank the voltage on my motor
without risking it to overspeed or to overheat (due to higher amps).
I have an older (1990) Tavria electric car. Its a realtively light car (2200
lbs)
with a 84V system (6v batts) and a 400A curtis controller plus a series
wound motor.
The motor is apparently a quality made series wound traction motor
from VEM Dresden, made in the early 90s. I don't have much on it other what
is
written on the motor itself:
vem elektroantrieb gmbh made in germany 174 a 12 kw 84 volt 3100 -
3500 u/min
The motor is a large unit. About 9" in diameter, it weighs 57kg (125 lbs)
and drives
the wheels through a basic 3 speed + reverse transmission. From these data
can
anyone make an educated guess on how hard I could drive this motor before I
risk
overheating/overreving it?
I would like to boost the power of the car a bit, I was thinking that I
could
add 2-3 12V SLA batts under full throttle (sort of both, bypassing the
controller plus
upping the voltage from 84V to 120V. I thought of using two large 1200A
contactors, one
to disconnect the controller, the other to hook up the motor to the batts.
If something
went wrong I would have 2 contactors in series, the main contactor from
albright plus
the boost contactor. I would activate the boost mode when I floor the peddle
through a
switch.
Alternatively I could replace the curtis with something more powerful like a
1k Zilla,
which I guess would be the saver way but would more than tripple the price
(and value?)
of the car.
In anycase, I would like to find out what I could do with this motor in
terms of making
my ride a bit beefier.
Thanks Guys
Markus

I do not expect to have the same performance as either the Fetish or the
Tesla. I am starting with about as much weight as either of the above without
batteries. Rolling body will weighs 1500 pounds with one motor 1700 with two
motors.
