" IMPROVEMENTS IN ELECTRIC MOTORS NO. 2 "

Filed Australian Provisional No. PQ9782. Priority date. 31 August 2000. The following statement is a full description of this invention, including the best method of performing it known to me: In a conventional electric motor, there are many magnetic fields which are created by the energising of a coil of copper wire, and which are not effectively used, or put to a useful application, such as generating an electric current to return some of the energy used in to a battery, back into the grid or original source of electric energy. The new electric energy, could be used to run lights, electric appliances, or even wired within the electric motor to reduce its own electric consumption. To my knowledge, the collection of these magnetic fields, with in an electric motor, has not been achieve before, and it is the object of this invention to show how it can be done. The same system used to create a new electric current, can be used to assist with the self starting of the electric motor, although the type of electric motor described in International Publication Number: W.O. 99/54990 and Australian Patent Application No. 23637/99 is self starting any way, when the commutation is correct.

One of the objects of this invention is to provide a simple, effective and low cost method to capture the magnetic fields with in the electric motor, not being put to any productive use, and to produce an independant usable electric current, while not increasing the electrical consumption of the working electric motor, or while the electric motor is being driven, to add to the already regeneration capabilities of the electric motor. The second object is to add to the self starting capabilities of the electric motor. In the Drawings:

Fig.1. Shows a simple round electric bobbin, wound with copper wire, with a base metal pressing, with metal extentions,one each side of the metal pressing, bent up and fitted with a top metal pressing with metal extentions bent down wards on the opposite sides to the base. A piece of metal tubing is fitted through the electric bobbin, and touches the base and top metal pressings. There are two ends of copper wire coming from the electric bobbin, one marked negative, the other positive, connection will be made to suit the application. Fig.2. Shows a simple round electric bobbin, wound with copper wire, with a base metal pressing, with metal extentions, one each side at opposite ends and one on one end only of the metal pressing, bent up and fitted with a top metal pressing with metal extentions bent down wards on the opposite sides and ends to the base. A piece of metal tubing is fitted through the electric bobbin, and touches the base and top metal pressings. There are two ends of copper wire coming from the electric bobbin, one marked negative, the other positive, connection will be made to suit the application. Fig. 3. Shows an electric motor as described in International Publication Number: W.O. 99/54990 an electric motor which uses both sides of the energised coils, and has permanent magnets rotating around both sides of the energised coils. Between the energised coils are fitted devices as already described in Fig.2, so that there is only an air gap between the turned up metal extensions and the ends of the energised coils, and the rotating permanent magnets. A device as descriped in Fig.2. is fitted in the gap between the energised coils. Fig.4. Shows an alternative arrangement to Fig.1. and Fig. 2., this arrangement is used when the two opposite magnetic poles are the same. The object is to collect the same magnetic pole flux^'s and have opposite magnetic poles at each end of the energised coil, with a metal connecting piece of tube passing through an energised coil, and touching both metal end pieces.

Fig.5. Shows an alternative arrangement to Fig.1, Fig.2. and Fig.4, this shows two devices, fitted so that each device has only two metal bent extensions, one to collect the North pole magnetic flux, and the other to collect the South pole magnetic flux, and then to be connected by a piece of metal tubing passing through an energised coil. Such a device is very basic and simple to produce, and could be connected to each other to increase voltage. All though not shown the bent up extensions could metal pieces attached which face the rotating permanent magnets, as described in Fig. 2. This invention in its simplest form consists of referring to Fig.1. an electrical bobbin 1 with copper wire 22 wound around it, with a metal base plate 2 with bent up extensions, the large bent up extension 5 and on the opposite side of the base a small bent up extension 6. This is fitted with a top metal plate with bent down extensions, the large bent down extension 8 and on the opposite side of the top a small bent down extension 7. A bolt 4 passes through a metal tube 21 which is fitted in the center of the electrical bobbin 1 , and through both top metal plate 3 and bottom metal plate 2, so that the same pole magnetic flux collected by the top metal plate 3 passes through the metal tube 21 to the opposite magnetic flux in the bottom metal plate 2. The operation of this device is to collect the same pole magnetic flux^'s created by the motor energised coils 11 , 12 and pass them through an energised coil 22. As the motor energised coils 11 , 12 change their magnetic pole flux^'s due to commutation of the electric current, the magnetic poles of the flux^'s being collected are also alternating, and creating their own independent electric current by the process of transformer induction, which is induced electromotive force in a stationary circuit by changing the current, which in this invention is done by the motor^'s commutator. Although physically quite distinct from motion induction, it is included in Faraday^'s law of electromagnetic induction, which relates the induced electromotive force in a circuit to the rate of change of the magnetic flux linking the circuit. This device shown in Fig.1. only works while the motor is being run with an electric current, and the commutator is functioning. In Fig. 2. there is an added bent up extention 10 and a bent down extention 9 these are positioned at opposite ends, and become operational when the motor is not being supplied with an electric current, and is being driven it become a generator, and generates an electric current as the permanent magnets pass the ends of the energised coils in the motor. These bent extensions 9, 10, also collect the changing magnetic flux and create there own electric current. When the motor is being run on an electric current, these devices are working on tranformer induction, but when the motor is being driven, they are working on rotational induction. In Fig.3. it shows a plan of an electric motor described in International Patent Application : W.O.99/54990. with outer permanent magnets 13 and inner permanent magnets 14 . Either the magnets 13, 14 can revolve around a fixed rotor, or the permanent magnets 13, 14 can remain stationary, and the rotor rotate, the function of this invention is not effected. In the illustration, the left motor energised coil 11 has copper wire 15 wound around it, and the right motor energised coil 12 has copper wire 16 wound around it, the ends of the wire are connected to a commutator, which switches the direction of the electric current to make the electric motor work, and at the same time providing the electric flux^'s to make this device function. It is not always realised that the tips 17, 19 of the energised coil 11 and the tips 18, 20 of the energised coil 12 have the concentration of the magnetic flux, and in the standard electric motor this energy is wasted, and not used. With the configuration illustrated for the electric motor it is now possible to collect this concentration of magnetic flux and make it produce an independant electric current, which can be used to power lights, charge a battery, or provide a power source for any electrical application. Fig. 4. shows another version of this device, which is used when the two opposite energised coil ends 17, 18 or 19, 20 are the same magnetic pole. In the motor illustrated in Fig.3. most of the same poles are adjacent tips 17,20, or 18, 19 but where that is not the case, this arrangement can be used. It is left to the motor designer what magnetic poles the tips 17, 18, 19, 20 will be.

Fig.5. Shows another variation to Fig.1 , Fig.2. and Fig. 4, in this case only one side of the motor energised coils 11 , 12 are used, the bottom metal plate 2 has the energised coil 1 trapped between the top metal plate 3, with the bolt 4 and tubing 21 fixed in the centre. This devise is basic and simple, and would be easily massed produced, it would depend on design requirements which device was used. As already described the faces facing the permanent magnets, would assist in the self starting capabilities of the electric motor, although this design motor is already self starting. Those skilled in the art would know that not all the described would be needed to make this invention, and any combination could be used. The size of the copper wire and number of turns would be determined by design requirements. It may be that a combination of the devices described would be used in any single

motor.
