Description

1 Description Initially, a Battery is used to power the Motor (2) via a switch. The switch will change the power supply from the battery to the small transformer (20) allowing the motor to be powered by one source, then the other. The output of the switch goes to the motor (2) which is attached to the pinion (3). The gear type for all gears must be the same, and can be bevel, helical bevel or magnetic gearing, however, magnetic gearing works by repelling forces and will minimize friction and would therefore be the better choice. The gears meshing point for the magnetic gearing can be either on the outer radius of the gears, or on the inside of the outer radius having the same pole, north or south, facing outward to mesh magnetic fields and create the gearing with no physical contact. The gearing magnets (4, 12 and 16) are rare-earth neodymium permanent magnets. The gears can be made of hardened or mild steel, or if magnetic gearing is preferred, a plastic, or alloy rotor can be used to support the gearing magnets. Both large gears (11 and 15) have the same radius as one another yet have a much larger radius than the pinion (3) and a larger radius than the magnets housing (17) for the purpose of creating reduction gearing (gaining output force, at the loss of output speed) to breach the ohm resistance of the generator. The first large gear (11) is attached to the axis shaft (6) which holds the copper coil windings (13). The axis shaft (6) is supported by a bearing (5) at either end which are upheld by a frame (1). Ruts (7) are milled into the axis shaft (6) for each output wire to bypass the bearing (5) to join onto several copper rings (21) which are set within a plastic end cap (8) and is attached to one end of the axis shaft (6) to hold the copper rings (21) within it. The plastic (8) separates the rings from each other and from the axis shaft (6). The rings (21) are a ring within a ring set up with each ring attached to an output wire from the coil windings (13) to transfer power through to the brushes (10) in the brush housing (9). The second rotor (15) holds the generators magnets (18) which pass over the copper coil windings (13) and are fastened to a pipe like housing (17) which can be made of an alloy, plastic, or reinforced fibreglass having a large bearing (14) at either end so the rotor (15) is free spinning upon the axis shaft (6) when the pinion is not in place. The ohm resistance radius must be smaller than the gear rotors (11 and 15) radius as to gain the best advantage from the gear reduction process hence the 2 generator extends horizontally along the axle length, so the greater the radius distance between the rotors magnetic gears and the ohm resistance radius, the easier the rotors will turn. When the pinion (3) turns, it will turn both large gears (11 and 15) in opposite directions, this will gain more frequent current induction into the coil windings (13) than if using reduction gearing with a single rotor and stator generator at the same gear ratio. All electrical energy created is sent to a large multiple output transformer via the communicator and brushes to have the voltage stepped down to a usable voltage. A second, smaller transformer may be needed to step down the voltage and ampere to feed the motor keeping the process going until a fault occurs or the generator is turned off. All surplus electricity can then be stored, or used as a direct power supply.
