02.00 FIELD OF THE INVENTION The invention belongs to the field of electrical power regeneration and technically related to the fields of applied Physics, mechanical, electrical and electronics engineering. 03.00 ADVANTAGES OFFERED BY THE INVENTION The main advantages of this device when compared with other power regenerative devices are very high efficiency, structural simplicity and easy operation. 04.00 ABOUT THE APPLICATION 04.01 REFERENCE TO AN EARLIER APPLICATIONS This application is based on the Sri Lanka national patent application No 13784, dated 17 th August 2005 and No: 14153 dated 07 th July 2006. This PCT application contains an improved description of the application No: 14153. 04.02 FORMAT OF THE AMENDED APPLICATION FOR IPE The original application has been amended by reducing the number of features disclosed earlier and re-describing the selected features in a continuous manner and in detail with minor adjustments based on the features that were inherently presented but not described in detail previously. The preferred embodiment disclosed earlier remains almost intact and any amendments with minor adjustments that have been done was in order to improve clarity required for the re-description. Therefore, the question of amendments going beyond the disclosure does not arise. The main body of the description containing 06 pages that were presented earlier in parts have been restricted and amended to two pages by following a standard method in which inventions are described. 04.03 SUMMARY OF THE INVENTION The dual drive electric regenerator (DDER) is a power regenerative device. The device comprises an armature core with a relatively large armature shaft for its power generating capacity. The power generation in the armature core being done by it's magnetizing current induced in the field coil. The armature shaft consists of a relatively large shaft diameter when compared with the shaft diameters of existing voltage - current generators with similar power capacity. The shaft being inserted to two inner rings of two bearing from inside and extends outwardly. The two bearings being placed and spaced apart and enclosed with an outer casing of sufficient material strength. The two ends of the armature shaft consist of two balanced flywheels. A driven flywheel rotates with the shaft from one end. A backend flywheel forms a passive drive upon rotation at the other end. The driven flywheel being first rotated by an impetus force and thereafter rotated to a predetermined upper speed and maintained at the upper speed by expending the rotational energy of an electric motor exerted as magnetic forces. This is being done by rotating dual magnetic fields emanating from permanent magnetic pole pieces attached to the circumference surface of relatively smaller driver flywheel placed close to the inner or the outer circumference areas of the driven flywheel consisting a specific even number of magnetic fields placed apart along the circumference surface area. The upper speed, which is the speed in which the armature core requires to be rotated being reached from an initial speed and maintained after synchronizing the interacting magnetic fields emanating from the permanent magnetic pole pieces attached to the driver and the driven flywheel. The electric motor consists with a power capacity, which is slightly more than necessary to overcome the retarding forces act against the rotation. Each flywheel generates an amount of power at the upper speed that exceeds half the generated power by the armature core. The power generated by the armature core, which is usually in the form of an alternating voltage - current being converted to a direct current and stored in a suitable storage device Part of the stored energy being reused by an electronic control process, basically to rotate the electric motor and to supply power to the electronic control module in order to sustain the control process of the power regenerative cycle of the device.

05.00 RACICGROUND OF THE INVENTION 05.01 THE ARMATUSREIS-LAFT The strength ofnarmnture shnfts consisting the cnore winding in existing electric generators such as motor vehicle alternators or synchronous AC generators have been determined in relation to the power capacity of the generator. That means as a general rule, larger the power capacity of the generator, larger the annature shaft. That is to withstand the retarding forces that get exerted and depending on the type of power coupling method that normally intended to use with a particular generator. There is no existing . generator with a specific power capacity intended to fix in the horizontal position that has been designed with a substantially larger armature shaft together with larger - stronger internal bearings and with a stronger outer casing than required. For example, there is no existing generator with a armature - field winding having a power capacity of say for example of 100 watts and having a metal'rotating armature shaft with two - inch diameter together with bearings having a two-inch bore and with a stronger casing to withstand the rotational forces of a flywheel that rotates at 1500 R.P.M and having a mass of say over one hundred Kilograms. 05.02 THE DUAL DRIVE FEATURE There is no commonly available electric generator, in which its armature shaft protrudes from both sides of the outer casing in a manner so that both ends could be used to impart external forces at the same time. This basic feature in which the armature shaft protrudes from both sides does exists but for a different reason and that is to provide a direct current from one end to magnetize the rotating armature coil through brushes and being used in old types of generators and still may be using in large generators employed in power stations. In this invention dual drives in which the armature shaft protrudes from both ends of the internal bearings have being used to provide driving forces from both ends in which one end being used as an active drive end while the other as a passive drive end. 05.03 THE FLYWHEEL Flywheels are being widely used in various types of machinery and almost all the traditional or the conventional flywheels have two unique features in common that is, its wider -heavier outer rim area with hollow areas in the middle. In this invention, a flywheel has being used without using those two features as it has been observed that the said two features are somewhat unsuitable for the design derived in this invention. The said wider - heavier outer rim causes rotational jerks at the start or during rotation or when stopping. However, having such jerks during stoppage would not cause much problem but at the start or more seriously during the rotation would chuse the driver and the driven flywheels to desynchronize from each other as maintaining synchronization is one of the main operational problems that this invention has to deal in order to operate the device successfully. Therefore, these two features have not been used. At the same it has been observed that the opposite features to those features are more suited. The word flywheel has been used to highlight the fact that it is the flywheel that generates the initial power as the word flywheel has being associated with the idea of accumulating energy. Therefore, the flywheel used in this invention is not a traditional one. 05.(4 THE ELECTRIC MOTOR It is known that electric motors consume a certain amount of current under free rotation and this is especially noticeable in DC motors. When a load is applied to its drive shaft, the consumed current tends to increase depending on the load. It has been observed by the inventor that this average current consumption tends to drops below the free running average current consumption under a certain condition during the rotational process. This observed phenomenon has been used in this invention to disclose certain electronic control process for stable rotational control.

This relatively large shaft diameter feature needs to be understood when compared with an armature shaft diameter of an existing voltage - current generator, where the shaft diameter is always being determined to satisfy the minimum requirements for rotation against the retarding forces and to that of the type of coupling required for an external power source. Therefore, this feature is not a case of merely making the shaft large but to satisfy a particular requirement. The requirement being the need to rotate a relatively large - heavy balanced flywheel combination to a high speed using the shaft as a drive shaft, which means the armature shaft (03) has to withstand a specific dynamic loading in relation to the specification of the flywheel combination that would generate an amount of power to exceed the chosen power generating capacity of the armature core (04). The two ends of the armature shaft (03) with the said core (04)' positioned near the center being inserted from inside to inner rings of two ball bearings (06) with sufficient dynamic loading strength placed and spaced apart to one another and enclosed within an outer casing (19) with sufficient strength to withstand the forces that enforces by the rotation of the flywheel combination. The armature shaft (03) extends outwardly from both ends through the inner rings of the bearings (06) to an extent that is sufficient to accommodate the lengths of the inner bores of the two flywheels that rotate as close as possible to the outer casing (19) and to accommodate an impetus wheel (23): A driven flywheel (01) being rotated from one end. A backend flywheel (02) forms a passive drive from the other end upon rotation by the driven flywheel. The driven flywheel (01) consists of two circular discs with different diameters with a common center bore. The larger disc being fixed as close as possible to the outer casing (19). The diameter of the smaller circular disc being substantially larger than the diameter of the center bore, herein substantially means several folds (for e.g. 10 to 15 to obtain optimum specification) of diameters of the center bore and depends on the factors such as the power capacity of the armature core (04), the speed and the power capacity of the electric motor (07), the specification of the speed increase mechanism. The optimum specification of the driven flywheel (01), which includes its diameter, the circumference -width and its mass (depending on the constructional material) of the driven and the backend flywheel being so chosen in relation to the said factors. An inner circumference surface (12) being formed in the inner face of the larger diameter disc of the driven flywheel by attaching or by machining a rim area (16). The thickness of the rim area (16) being just sufficient to imbed magnetic Pole pieces (11) with two slightly curved surfaces consisting two Pole faces in which the thickness of a Pole piece being relatively smaller than either the length or its width. Magnetic Pole faces being attached to the inner circumference surface (12) or to the outer circumference surface or in manner in which the two Pole faces of the Pole pieces protrudes outwardly from both inner and outer surface of the rim area (16). The outer circumference surface (13) of the larger diameter disc and the outer circumference surface the rim area (16) being of same diameter. Specification of the backend flywheel being similar to that of the driven flywheel. Therefore, the masses of the two flywheels being same in order to achieve the required balanced rotation. The driven flywheel (01) being rotated by a rotational impetus force using the impetus wheel (23) manually or through a starter motor with a speed increase mechanism using a pulley wheel - belt - pulley wheel mechanism or gear wheel mechanism with disengagement mechanism. After the rotational impetus force being used, the driven flywheel (01) being rotated to its predetermined upper speed (42) from a set initial speed (39) by magnetic forces exerted from the dual magnetic fields rotated close to the circumference area of the driven flywheel (01), which is either to the inner circumference surface (12) or to the outer circumference surface (13). The driver flywheel being rotated by the electric motor at the same time to the required speed for magnetic synchronization between the driver - driven flywheels. Alternatively, the driven flywheel (01) being rotated to an above upper speed (44) than the predetermined upper speed (42) by the said starter mechanism and thereafter allowing the flywheel combination to slow down until the predetermined upper speed is reached by slowing down under gravitational and frictional forces and gets synchronized. The driver flywheel being rotated at the same time to match the required upper speed to achieve the necessary synchronization. PAGE - 03 [DDER] 06.02 THE MAGNETIC FIELD FORCES The preferred embodiment (Fig: (01)) describes the method of magnetic forces exerting to an inner circumference surface (12) or to an outer circumference surface (13) consisting a specific even number of niagnetic fields (15) placed apart to one another. This specific even number being determined in relation to the circumferential length of the driven flywheel and from the condition that ensures the magnetic synchronization with the driver flywheel in which the optimum rate of speed varying capability being achieved. The magnetic fields (15) being made to emanate from permanent magnetic Pole pieces (11) place consecutively along the inner circumference surface (12) with equal spacing between the Pole pieces where the length of the spacing being nearly twice the length of a Pole piece or equal but not more. The attached magnetic Pole pieces (11 ) consist of same type of Pole protruding inwardly or outwardly from the attached circumference surface The dual magnetic field forces [Figs: (04) & (05)] being formed by attaching two permanent magnetic Pole pieces to the outer circumference surface of a relatively smaller driver flywheel (14) with equal spacing between the Pole pieces, where the spacing length and the length of a Pole piece being of equal length or the Pole piece length being slightly more than the spacing length but not less. The driver flywheel (14) being rotated by an electric motor (07) shaft directly fixed to the center bore of the driver flywheel (14) or through a speed increase mechanism consisting a pulley wheel - belt - pulley wheel or a gear wheel type mechanism. The power capacity of the electric motor (07) being chosen to be slightly higher than the power capacity requires to be expended to rotate the driven flywheel together with the backend flywheel to overcome the retarding forces enforce by the armature core (04) and to any internal or external frictional forces experience by the device. The rotational power of the electric motor (07) being transferred as magnetic attraction or repulsion field forces in which a magnetic Pole piece attached to the said driver flywheel exerts magnetic attraction or repulsion force from the Pole pieces attached to the driven flywheel from a leading or a lagging position relative to the direction of rotation of the driven flywheel where same type of Poles being attached to the driven flywheel consecutively to the circumference area while opposite or same type of Pole pieces to that of the Pole pieces attached to the driven flywheel being attached to the driver flywheel's circumference surface consecutively with equal spacing between the Pole pieces. 06.03 TE ELECTRONIC CONTROL PROCESS Figure (08) shows the basic concept of the electronic control process that controls the rotational process, which include the synchronization of the two interacting magnetic fields of the driven (01) and the driver flywheel (14), the speed increase process [Fig (07))] of the driven flywheel by controlling the speed of the electric motor (07) at a control level and resetting the rotational process in the event of a desynchronization of the two flywheels due to magnetic decoupling of the two interacting fields. The basic rotational process is as follows: when the predetermined upper speed being achieved from an initial speed: - The electric motor (07) first being rotated to an initial speed (39) suitable for the synchronization of the driver (14) and driven flywheel (01) from a starter switch (25) by turning on the initial voltage setting circuit (26). At the same time, a rotational impetus force being given to the impetus wheel (23) to rotate the flywheel combination to a slightly higher speed than required for magnetic synchronization of the two interacting field forces. The average current consumption measuring circuit (35) continually measures the average current consumption and compares it with the current consumption when the two flywheels are synchronized. When the current consumption becomes equal then the desynchronization control circuit (29) initiates a delay through the time delay circuit (36) for the driven flywheel (01) to achieve rotational stabilization. Time delay circuit signals both the electronic switch (27) and the automatic voltage control circuit (30) at the same time to disconnect the initial voltage setting and start the automatic voltage increase process. A timer circuit (31) chooses both the time period for the digitally select voltage levels as well as the predeternmined time delay (43) between specific amounts of speed increase (37), which is in electronic terms voltage increase levels until the counter halt the counting when the upper speed (42), which is the upper voltage level is reached. In the event of a magnetic desynchronization between the driver - driven flywheels that could occur due to an external influence or due to a voltage fluctuation to the electric motor, then the average current consumption drops. When this occurs the time delay circuit (36) in the desynchronization control circuit (29) switches through the electronic switch (27) the initial voltage setting circuit to reset the electric motor to the initial speed (39) while AVCCMC (35) checks the current consumption before signaling AVCC (30) to resume the speed increase process until the US (42) is reached. This way the device maintains its rotational process. PAGE - 04 [DDER] 4 44-. M~ C~- -- t--- 24 '1flfl7 41 7ff f..
