Progress of Models and Prototypes.
I have built a small opertional model. It uses 8 ceramic magnets 0.5" thick (x) 1" width (x) 2" length. They are glued around the periphery of a 7" grinding disc (makes a good flywheel). Eight 3/8 bolts (coil cores) are positioned head first under and along the radial center lines of the ceramic magnets at a radius of 3.9375". That makes a 7.875" diameter. These bolts are wound with a total of 2 lbs. or 23 gage magnetic wire in sufficient thickness so as to allow 12 volts to produce enough magnetism to counter the magnets' attraction to the bolt heads. 633.7 ft./lb. so two pounds has 1267.4 feet and each coil has 158.425 feet of wire. They are wound through a bolt shank length of 58mm or 2.28" Motor specs used/derived in/through calculations:
HORSEPOWER = .042 hp
WATTS CONSUMED = 9 watts (circuit energized 50% of time)
WATTS PRODUCED = 26 watts
EFFICIENCY = 347 %
VOLTAGE = 12 volts
RESISTANCE = 8 ohms
CURRENT = 1.5 amps
RPM = 300 rpm
TORQUE = .737 ft/lb (eight pulses per revolution)
ARM LENGTH = .328 feet
ARM FORCE = 2.247 lb.
Here's how I arrived at these conclusions
RESISTANCE
The resistance was measured with an ohm meter to be 8 ohms
VOLTAGE
I'm using a 12 volt battery
CURRENT
Voltage = Resistance x Current therefore current is 1.5 amps
TORQUE
Torque is measured in foot/pounds. The radius of my motor is .328 feet and a force of
2.247 lbs is needed to move the rotor when no power is supplied to the motor. The
magnets have "settled" on top of the cores. .328' x 2.247 lb = .737 ft/lbs of torque.
RPM
The rotational velocity was measured at 300 rpm
WATTS CONSUMED
The formula Watts = Voltage x Current determines the motor uses 18 watts. However the motor
is energized only 50% (or less) each revolution therefore it really consumes only 9 watts
HORSEPOWER
The formula for determining horsepower is Horsepower = Torque x RPM x .0001904 therefore
.737 x 300 x .0001904 = .042 hp
WATTS PRODUCED
1 horsepower = 745.712 watts therefore the watts produced is 31.3 watts
745.712 watts 31.3 watts
------------- = ------------
1 hp .042 hp
EFFICIENCY
Watts produced divided by watts consumed gives efficiency. Therefore 31.3/9 = 347%
The following are other equations and measurements used which give more detail.
1020 ml of water is needed as a weight to turn the rotor past the magnets.
1.020 liter = 0.26945544 gallons
1 gal water = 8.3378 lbs.
1 gal .2694554 gal
---------- = ------------
8.3378 lbs 2.247 lbs
2.247 lbs. is needed at 3.938" rad to turn the motor.
3.938" / 12" = 0.328' arm
2.247 lbs. x 0.328' = 0.737 ft/lbs. of torque
observed rpm is 300 rpm
HORSEPOWER = TORQUE (x) RPM (x) .0001904
.042 hp = .737 x 300 x .0001904
1000 watts = 1.341 horsepower
745.712 watts = 1 hp
745.712 watts 31.3 watts
------------- = ------------
1 hp .042 hp
26 watts is produced
resistance of circuit is 8 ohms
12volts = 8ohms x 1.5amps
18watts is consumed = 1.5amps x 12volts
0.737 ft/lbs. of torque
180 rpm
0.0253 hp
18.836 watts is produced
0.737 ft/lbs. of torque
250 rpm
0.035 hp
26 watts is produced
18 watts is consumed but the circuit is only energized 50% of the time per revolution
so really only 9 watts is consumed.
26 / 9 =
290% efficiency
1 g = .035 oz.
1 kg = 2.2 lbs.
1 kilowatt = 1.341 horsepower
Who needs this car?
I need this car. You or someone you know might too. Because of it's utter simplicity it is very reliable and easy to work on anywhere in the developing world. Your interest is worth its weight in gold. Keep in touch and visit the site frequently to keep current on the development of this car.
Description of 150 hp motor.
The LaFonte Research Group Magnetic Equilibrium 12 Volt dc Pulsed Magnet Motoris the heart and soul of the McGuire Electric Car.
CALCULATING HORSEPOWER
Electric vehicles are notorious for poor performance. Not so with mine. I fully expect to have 150hp to 300hp 12 volt dc
motors which can easily fit in any existing car, truck, 4wd or SUV.
The two forces which contribute to the horsepower rating of any engine are TORQUE and RPM (revolutions per minute).
You can find a detailed explanation of this formula at
How Stuff Works.com
HORSEPOWER = TORQUE (x) RPM (x) .0001904
One little neodymium magnet 1" x 1.25" x .25" can lift 85 lbs. The large magnets to be used in my motor can lift hundreds of
pounds each. For 150hp I need magnets which can produce at least 112 pounds of force each, and this at an easy to reach
500 rpm. My large magnets easily meet this specification. There are 16 magnets in the rotor (8 on each side) and there are
eight magnetic attraction power pulses every revolution.v
If my magnets were exactly 112 pounds powerful the horsepower per rpm is as follows:
For now I need to reach full power at 500 rpm in my calculations because I don't know yet how many rpms this motor will turn.
As you can see this motor is very powerful. I have received emails from people who need at least 150 hp in their four wheel
drive vehicles. This requirement is easily achieved and surpassed. I predict the actual horsepower of my motor to be double
of the figures shown above.
Several interested electrical engineers have written without first studying the motor as
described on this website and have written skeptical emails to me saying it's impossible to have
a powerful motor for a car using only 12 volts. This is NOT a 12 volt DC electric motor. It is
true that without the 12 volts DC power it won't run. However the 12 volts DC current supplied
to the electromagnets in the stator is NOT strong enough to repel the permanent magnets in the rotor. If you turned the
power on and left it on continually the motor will NOT run. It will develop ZERO hp. You could
open the motor's cover and grab the rotor with your hand and spin it freely.
Can 12 volts supply enough magnetism in the electromagnets to neutralize the permanent magnets'
"grip" on the iron cores of the coils? Yes. There are numerous 12 volt DC electromagnets on the
market today which will lift hundreds of pounds each. This motor does NOT require power
anywhere near that strong. McMaster-Carr has an excellent website from their catalog where you
can see a listing of these electromagnets and read their specifications. Here is the graphic
from that catalog page:
1000 rpm = 300 hp
2000 rpm = 600 hp
3000 rpm = 900 hp
A quick note to electrical engineers visiting the site.
* A quick note to electrical engineers visiting the site. You can't apply traditional engineering formulas to this motor. It is not an electric motor. The driving force is not electrical in origin. The current flow in this motor does not repel the permanent magnets. The electromagnet coils only produce enough magnetism to neutralize the magnet's attraction to the iron cores of the coils. The forces involved here are:
1. Magnetic attraction of permanent magnets to the iron cores of the coils.
2. 12 volt current flow through coils to neutralize the magnetic attraction of the permanent magnets.
3. Back EMF generated by the passage of the magnets past the coils.
A diode prevents current flow before the magnets reache the coils.

This graphic shows the "commutator" which is really a bridge between the two brushes. It's a solid chunk of copper turned on
a lathe and then has grooves cut out for plastic nonconductive filler material.
mcmotorrotorcommutator.gif
The LaFonte Research Group is developing an optical commutator which eliminates moving
parts and enhances reliability and ease of maintenance. I'll keep you posted on that.
This "easier to view" graphic illustrates the electrical system of The LaFonte Research Group Magnetic Equilibrium 12 Volt dc Pulsed Magnet Motor.
mcmotornolafontesaver.gif
When the motor is turned off all magnets fixate in front of the cores of the coils and stops
the engine. To start the engine the coils are energized and the rotor is set in motion by a
small starter rotor of coils and magnets. The starter coils energize repelling the magnets as
seen in this animation. When the starter is no longer needed another circuit makes it a generator.
These coils do not have iron cores. When red the current is flowing, when yellow no current is
flowing.

Common Conventional Car Problems.
But first... Here are some common car problems. How many times have these happened to you?

Safety Comparison Between My Car and Other Electric Vehicles.
Typical electric car conversion kits use complicated high voltage dc or ac motors, regulators, controllers, etc.... Take a look at some examples. These are good electric vehicle systems and well proven technology but I believe my concept will appeal to you as well, even better.

My electric car is simpler, safer and more affordable than anything I have seen on the market. It works in all cars/trucks/SUVs.
The electric motor is a 12 volt dc electromagnetic pulsed magnet motor. The only parts subject to wear are the sealed precision
ball bearings.
Extremely strong Neodymium rare earth magnets provide the power as they are attracted to the "magnet attracting" soft iron
cores. The electromagnet coils are only strong enough to produce a "neutralizing" same pole repulsion force which effectively
"breaks" the magnetic attraction between the rotor magnets and the stator soft iron cores. 12 volts is safe. Next time you open
your hood put one finger on the positive terminal of the battery and another finger on the negative terminal. Nothing happens.
12 volts is perfectly safe for humans, and I guess dogs and cats.
How Much Does This Motor Cost?
I'm working on that now. Components include:Aluminum or Composite Stator Frame. $400 Estimated Soft Iron Electromagnet Cores and $2800 Estimated Magnetic Wire Coils. $10 / lb. Aluminum Rotor. $200 Estimated Ball Bearings. $100 Estimated Neodymium Magnets. $3200 Estimated Transmission Plate. $500 EstimatedObviously, the motor is the most expensive part of the McGuire Electric Car.
I'm shopping the internet for the best prices on all of these components.
The McGuire Electric Car uses a Self-Sustaining Battery Charger
The batteries are recharged WITHOUT the need for gasoline generators, wind generators or plug-in battery chargers. All power needed to recharge the battery is onboard the car. It's not free energy or "something for nothing" but it is high tech engineering made cheap and practical. You can read all about them at Eagle Research.Here are several battery charger devices from Eagle Research.
Primary Focus Right Now.
My focus is on the design and engineering of The LaFonte Research Group Magnetic Equilibrium 12 Volt DC Pulsed Magnet Motor specifically for my need. I am soliciting assistance from interested parties including vehicle operators and reputable magnet and electromagnet manufacturers in the USA.I do need financial assistance as well as engineering assistance. I have had several engineers email me with information. Thanks guys. If you are poor and/or of limited means God does not want you to send me any money! Your continued interest is worth its weight in gold. Keep in touch and visit the site frequently to keep current on the development of this car.
I need the help of others to make this vehicle a reality to those who need it most.
