A LOW TECHNOLOGY ELECTRIC MOTOR WHICH MAKES USE OF BOTH SIDES OF THE ENERGIZED COIL TO PRODUCE MORE POWER FOR THE SAME AMOUNT OF ELECTRICAL ENERGY CONSUMED.
THE NEW "H" SHAPED ENERGIZED COILS USED IN THE ELECTRIC MOTOR. PERMANENT MAGNETS ARE POSITIONED BOTH SIDES OF THE COILS.The Electric Motor is for either A.C. or D.C. current, and has the choice of a carbon brush on a flat copper commutator ( which was specially developed for this motor ) and is ideally suited for a D.C. in the Hub Electric Wheel Motor for use on a Bicycle or Electric Car, and is used in area`s where low technical repairs are only available. Or there is an electronic commutator, best suited for stationary applications, where high technical repairs are available. This new electric motor is still being developed, although working prototypes have been made and are being tested, to establish how much more power has been obtained from the use of magnets both sides of the energized coil. This Electric Motor is initially intended for use in the front wheel of a Bicycle, to turn the normal push bike into an electric powered bicycle.
In simple terms, to explain this invention : if we look at figure 1. which is the basic electric motor.
This is made up of "T" shaped arms which are joined at the center. With copper wire wound around the stem of the "T" shape, and connected to a commutator ( which changes the direction of the electrical current ). An electric current is passed through the copper wire creating a north magnetic pole one side of the energized coil, and a south magnetic pole the other side. These magnetic poles alternate as the direction of the electric current is changed. The operation is that when the magnetic pole on the outside of the rotor comes in the vicinity of a magnetic field in the stator ( the outside magnetic casing ) the principle of like magnetic poles repel, and unlike magnetic poles attract comes into play to force the rotor to rotate. It is important to note that the magnetic poles either side of the energized coil are of equal strength, but the magnetic pole the side that forms the center of the rotor can not be used to rotate the rotor. 50% of the potential power of the energized coil is lost.

AWARDED to ETTRIDGE COMMUTATOR
At the International Exhibition of Inventions & New Products held in Geneva, Switzerland, from 31st March to 4th April 2004. There were approximately 1000 Inventions Exhibited, with the GOLD MEDALS being awarded for the best inventions shown.
The Gemini Electric Motor uses three methods of commutation or controllers. The first two are carbon brush systems, and the third uses electronic controllers.
The first system is a flat base carbon brush commutator, this consists of a flat base with copper segments positioned in a circle, with the carbon brushes at 90 degrees to the flat base. The unique feature of this carbon brush system is that a neutral copper segment is positioned between the negatively charged copper segments, and the positively charged segments, so the carbon brushes can not touch both the negative and positive charged segments at the same time. Making it impossible to short the two electrical charges.
The animation below shows two carbon brushes A and B positioned on the flat base. If six energised coils are used, there are three sets of carbon brushes, but the animation only shows two for simplicity.
The inner and outer rings simply take the negative or positive electric current to the center segments, they may act as slip rings in some applications. Below is a picture of an actual flat base with only the center segments.
The carbon brush holder, ensures the carbon brushes are held in the correct positions in relationship to the flat base
The second carbon brush system works on the same principal as the first, but with the carbon brushes arranged radially around the armature. It would appear to be similar to the conventional carbon brush system, except that a neutral segment is positioned between the active negative and positive segments. It is important that the neutral segment is wider that the carbon brushes.
Below is an animation of the carbon brushes arranged radially around the armature.
The third system of commutation is an electronic controller, which electronically switches the electric currents, by use of a hall effect sensor to detect the position of the magnets in relationship to the energised coils. The electronic circuit also controls the speed of the electric motor.
