The Electromatic Motor Car
« on: December 06, 2018, 11:27:24 PM »
I’ve had the following file for over 20 years, and although the contents may be dated and short on detail (one page missing), I believe it is still relevant today …. so I post it for your perusal.
The original file had photos of the working prototype but they are of such poor quality that I am unable to scan them. I can offer only one photo showing part of the working prototype. The base vehicle used was a front wheel drive Cadillac Eldorado.

The vehicle was also called the “Hawthorn Regenerating Electric Auto.” (Late 1970’s), do a Google search and you may still find it.


A Description

In order to better serve your interests and to ensure your understanding we shall employ here a technique of verbal graphics, which will enable you to properly visualise the Electromatic Motor Car and its operating principles.

Allow me to be your guide.

Now that you have arrived at our facility we are walking into our shop where the Electromatic Motor Car awaits us. And there it is, directly in front of us.

The first thing that you notice is that our shop model is a functional model, stripped of its body and revealing the vehicle frame with its drive system totally exposed.

The vehicle frame, its wheels and steering equipment are more or less conventional, so we will not focus our attention on these points. Our interest lies in the unconventional equipment.

As you continue looking at the vehicle you will notice that not only does it have the usual rear-end differential, but also has a similar differential provided for the front wheels. This seems a bit odd, but you will soon understand why.

Our attention now shifts and we notice that the system components consist of a 5 to 16hp, 36 volt, DC drive motor, 6 x 6v heavy duty automotive batteries, one 12 volt automotive battery, 4 x 12v automotive type alternators, plus a number of belts and pulleys.

As we inspect the vehicle further you notice that ordinary foot pedals are provided for breaking and acceleration, but something seems to be missing……. of course, there is no gear shift control because on the Electromatic Motor Car none is needed. Acceleration from standstill to full speed is accomplished by merely depressing the accelerator pedal. A simple hand-lever is provided for switching from forward to reverse motion.

Now that you have seen the components of the Electromatic Motor Car it is time to shift our attention to the way in which the drive system functions.

We will begin with the initial energy source which is the bank of 6 x 6v batteries which are connected in series. Together they give us a source of 36v of DC electrical energy. This electrical energy is applied to our DC drive motor through a variable voltage control device that is actuated by the accelerator pedal - thus providing operator control of drive motor speed. Utilising the applied DC electrical energy, the drive motor converts this energy into kinetic energy which is then available from the pulleys mounted on the motor shaft.

Thus far our drive system resembles an ordinary electric motive system, but here is where the resemblance ends.                                                                                                                                                                                                     

Electrical Energy is transferred by v-belts directly to the rear-drive differential unit via its pulleys. Kinetic energy applied to the rear wheels via the differential unit then propels the Electromatic Motor Car into motion.

Our car is now in motion. Due to the total vehicle weight or mass, operating with inertia, our vehicle like any other moving mass tends to remain in motion in accordance with the amount of kinetic energy momentum built-up within it. It does not want to stop moving. It can properly be said that our vehicle, once in motion, has established for itself a new equilibrium of motion which is highly resistant to slowing down.
Now….. The gross vehicle weight of the Electromatic Motor Car is roughly 2000 pounds and this mass is now in motion at highway speeds. At this point and due to the fact that this vehicular mass has within it a surplus of energy we are enabled to remove a part of its stored kinetic energy without reducing the speed of the vehicle.
Here is where the front-end differential that you noticed earlier comes in. 

The forward momentum of the vehicle causes the front wheels to roll. This motion transfers through the front end differential to its drive shaft on which are mounted v-belt pulleys. These pulleys in turn are belted to three 12v alternators. At this point kinetic energy is converted back into electrical energy.
The alternator outputs are then fed back into the initial battery energy source through standard automotive type regulators. In our system the alternators operate in parallel to the reverse side of a series loop. Each alternator supplies current for two of the cells in the six cell energy pack, so you can see that the batteries become capacitors after the system in in motion. Notice what is happening here. Six batteries are in series and three alternators are in parallel. Each alternator charges two batteries.

Now…. since the metal cases of these alternators are electrically common with the negative side of each alternators output, we obviously cannot allow these electrically hot alternator cases to electrically contact each other. Therefore, we electrically isolate each alternator case from vehicle chases ground in order to avoid having the paralleled alternators short-circuit each other. We can say that our alternators and our batteries are floating electrically above vehicle chassis ground potential.

It has now become obvious to you that we have a CLOSED LOOP SYSTEM that self-powers while sustaining its highway speeds.

Let us summarise briefly the Electromatic Motor Car drive system.

1. Electrical Energy initiates from the batteries.
2. Is converted to Kinetic Energy by the drive motor.
3. Drive motor imparts Kinetic Energy Momentum to a Rolling Mass.
4. Operating at highway speeds this Rolling Mass has a surplus energy over and above that needed to  sustain vehicle motion.
5. The surplus part of this energy is converted back into electrical energy which keeps our initial power source battery fully charged.

This is a balanced system in which energy is balanced with energy returned leaving the surplus to sustain car motion.
Another viewpoint would be that the resultant physical action remains the same.

Now that you are acquainted with the mechanics of the Electromatic Motor Car we have a treat in store for you. We are now going to climb aboard for a test drive. You will notice that I am taking the seat beside the driver’s seat. This is because you are going drive. You are now seating yourself beneath the wheel and I am pointing out the simplicity of operating our car. I have shown you the key switch which you are now turning on……and nothing seems to happen. No stater noise, no motors starting sounds, no nothing. Is it on? you ask and I answer of course. Try depressing the front pedal, and as you do the car silently and smoothly begins to move. Gaining speed we move swiftly down the highway and the only sounds you hear are the tires rolling on the pavement and the whispers of the wind. Now we are up to fifty miles per hour and you are amazed at the smooth continuous speed changing and the total absence of motor noise. It is strange after so many years of driving ordinary cars.
We are now stopping for a traffic signal and as we wait one would be totally unaware that the car is on were it not for the dashboard indicators. We have run our course and you are now driving the car back into our shop.
