Description
"ELECTRICAL ENERGY GENERA SYSTEM FOR A MOTOR VEHICLE"
BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION
The present invention relates to electric power genera systems for motor vehicles.
2. DESCRIPTION OF THE RELATED TECHNIQUE
To generate electrical power in a motor vehicle, a conventional alternator is typically coupled by a drive belt to the crankshaft of the vehicle engine. This traditional power generator project can have a number of limitations. First, the traditional location of the alternator in the engine of the vehicle can cause the "wrapping" of the total package of the engine to increase in size. When the packing in an engine compartment is tight, this can be a significant disadvantage. Second, a conventional alternator can be a costly means of genera electricity in a motor vehicle. Means must be provided to drive the rotor of the alternator and the rotor itself can be seen as a redundant rota element when considering that the engine crankshaft is already rota. A conventional alternator can also be seen as a costly means of genera electricity because a given alternator has a fixed power output capability. In contrast, a given motor vehicle model can have a wide array of optional features that presents a variable requirement for electric power generation capacity. Using a single alternator with sufficient genera capacity for high containment vehicles, it can represent a waste of genera capacity when used in a smaller containment vehicle of the same model. Therefore, an electrical power genera system for a motor vehicle that is more space efficient and cost effective can provide advantages over the prior art.
COMPENDIUM OF THE INVENTION

The system comprises a rotary member coupled coaxially with the crankshaft for rotation therewith, the rota member including a portion of the electric power genera rotor. In addition, the system contains a housing that at least partially encloses the rota member. The system also includes at least a portion of the electric power genera stator positioned in opposition to the portion of the electric power genera rotor, wherein at least a portion of the electrical power genera stator is coupled with the housing and extends through an opening in the housing. The present invention also provides a second generator system for a motor vehicle having a motor. The system includes a flywheel coupled with the motor and including a portion of the electric power genera rotor. The system also comprises a housing that at least partially encloses the steering wheel. The system further comprises a plurality of stator portions of electric power generator placed opposite the portion of the electric power genera rotor. The present invention further provides a method for manufacturing a generator system for a motor vehicle having a variable number of electric charges, a motor, a flywheel coupled with the motor and having a rotor portion genera electric power. The method comprises selec a variable number of generator modules, each generator module comprising a portion of the stator generator of electrical energy, in variable number of generator modules, being sufficient to assume electrical energy to the variable number of electric charges.

DETAILED DESCRIPTION OF THE PREFERRED MODALITY
Referring to Figure 1, a generator system according to one embodiment of the present invention will be described. The system includes generator modules 20 and a flywheel 22. The generator modules 20 are fixed with bolts by the bolts 24 in the bell housing 26. The bell housing 26 encloses the steering wheel 22 which is bolted in a conventional manner to the crankshaft of a motor vehicle engine (not shown). A portion of the periphery of the flywheel 22 forms a rotor 28 having teeth 29. An electrical connector 30 is provided in the housing of each generator module 20. Sufficient sealing means such as gaskets are provided to prevent leakage of water and dirt beyond the generating modules 20 into the interior of the bell housing 26. Referring further to Figures 2 and 3, the steering wheel 22 will be described in greater detail. The flywheel 22 includes a conventional flywheel portion 32 having holes 34 through which the flywheel 22 is bolted to a crankshaft of the engine (not shown). Welded or otherwise properly secured to the portion 32 of the conventional steering wheel, there is a collar 36 of steel. Welded by points or otherwise appropriately secured to the collar 36, there is a rotor 28. The rotor 28 is preferably manufactured from laminations of ferromagnetic material, such as iron. The rotor 28 is preferably constructed of material that is not permanently magnetized. The rotor 28 includes teeth 29. Welded or otherwise appropriately secured to the collar 36, there is a ring gear 42. The ring gear 42 is provided to carry out the conventional function of a flywheel ring gear (i.e., interface with a crank motor for the purpose of starting the engine).
It should be noted that the inertia of the flywheel 22 is not necessarily changed by the addition of the rotor 28, provided that a mass amount is removed from the portion 32 of the conventional flywheel. Reference is now made to Figures 4 and 5. The generator modules 20 each include a stator portion 50. The stator portion 50 is preferably laminated and made of a ferromagnetic material, such as iron. The stator portion 50 comprises three poles 56, 58 and 60. Each pole contains a number of teeth 62 positioned opposite the teeth 29 of the rotor 28. Wrapped around each tooth 62 of the stator portion 50, there is a portion of a stator. 64 energy winding. Preferably, the winding 64 of energy is a three-phase winding with the phases alternating between the teeth 62. The three phases terminate through the wires 65, 66 and 68 in the rectifier assembly 70. The rectifier assembly 70 is provided according to any configuration known in the art. For example, the rectifier assembly 70 may be a full-wave rectifier of six diodes. The direct current (DC) output of the rectifier assembly 70 is provided through the wires 72 and 74 to two cavities of the connector 30. The voltage in the wire 72 has a positive polarity with respect to the voltage in the wire 74. The generator modules 20 each further includes a field coil 52. The field coil 52 is coupled to its "raised" side with the positive output wire 72. On its "low" side the field coil 52 terminates in the consumption of a field effect transient (FET) 75. The FET source 75 is coupled with the output wire 74. A wire 77 coupled with the FET gate 75 is provided on a terminal of the connector 30. The field current for the field coil 52, therefore, it is provided with the energy created by the generator module 20 and can be controlled through a low current signal that is provided to the wire 77. When the direct current field current is provided through the coil 52 field, the poles 56, 58 and 60 are magnetized. Pole 56 is magnetized with a magnetic polarity and poles 58 and 60 are magnetized with the opposite polarity. The rotation of the rotor 28 then causes a magnetic flux through the teeth 62 of the stator portion 50 to vary as the teeth 29 pass the rotor 28. This variable flow generates three-phase electrical energy in the energy winding 64.
The configuration of the stator portion 50 towards the central pole 56 and two "half poles" 58 and 60, provides an advantage through possible alternative configurations. For example, if only two poles were provided, all the flow generated by the field coil 52 would pass in a single path. This would have to saturate the iron in the rotor 28 unless a considerable thickness of iron was provided. However, in the present design, the flux generated by the field coil 52 is divided, a portion 76 returns through the pole 58 and a portion 78 returns through the pole 60. The tendency to saturate the iron of the rotor 28 is reduces, allowing the rotor 28 to be manufactured very thin. This reduces the size of the rotor 28, providing an advantage for packaging the generating system of the present design. Reference is now made to Figures 1 to 6. In the present design, multiple generator modules 20 can be provided. Three of these generator modules 20 are shown in Figures 1 and 6. The direct current power outputs of these generator modules 20 can be combined together (such as by connecting parallel or with wire O-ring) to provide power to charge the battery 80 and operating other electric charges 82 of the vehicle. The means for combining the direct current outputs of the generator modules 20 is provided, for example, in the vehicle wire harness. In addition, the voltage regulator 84 is provided. The voltage regulator 84 is preferably coupled through the circuit 85 with the control field current to all field coils 52 of the generator modules 20. Any voltage regulator design known in the art can be employed as the voltage regulator 84. A detection line 86 can provide battery voltage feedback to the controller 84, which then controls the field current to the generator modules 20 in order to effect a predetermined reference voltage on the battery 80. the inclusion of FET 75 for the control of the field currents in the generator modules 20 is of specific advantage in situations such as here, where the voltage regulator 84 simultaneously controls the field currents in the generator modules 20 through a single circuit 85. This single circuit 85 , which has a fairly long path and a number of connections, may be susceptible to inadvertent short circuits. The short circuit can occur, for example, with ground, if the circuit of the wire 85 is rubbed against a metal component in the vehicle, skimming through the insulation in the wire.
- Í ¬
With the voltage regulator 84 providing only a signal level signal to control the field currents through the FET 75, as opposed to directly providing the field current itself, a short circuit in the circuit 85 will not have permanently damaging consequences to the circuit 85 or voltage regulator 84. In case a significant number of electric loads 82 constitute the "optional" equipment in the vehicle, a variable number of generator modules 20 may be provided. That is, the number of 20 generator modules installed in a specific vehicle will depend on the amount of "optional" equipment in that specific vehicle. Therefore, two vehicles of the same model assembled in the same assembly plant may have a different number of installed generator modules. This capacity allows the assembly of vehicles to be carried out optimally, avoiding the installation of an unnecessary electric power generation capacity in vehicles. If a vehicle is designed to accommodate a varying number of modules 20 generators, covers with appropriate sealing means can be bolted through any of the openings in the bell housing 26 since the generating modules 20 are omitted.
Referring now to Figure 7, an alternative configuration for a generator module 20A is illustrated. Here, the portions of the field coil 52 wind around each of the poles 56, 58 and 60. The result is that the total size of the generator module 20a can be reduced, since the large "end turns" will be eliminated. associated with a single winding around the pole 56. Another feature illustrated in Figure 7 is the provision of two permanent magnets 90 and 92. The permanent magnet 90 is provided between the pole 56 and the pole 58. The permanent magnet 92 is provided between the pole 56 and the pole 60. The permanent magnets 90 and 92 are oriented to counteract the exhaust flow that can tend to bind directly the pole 56 and the poles 58 and 60, respectively. This exhaust flow does not link the rotor 28 and, therefore, does not do any productive work, the exhaust flow only acts to saturate the poles 56, 58 and 60. Countering that exhaust flow can improve the efficiency of the 20A module generator. The permanent magnets 90 and 92 can be adhesively fixed within the generator module 20a, such as, for example, with the same epoxy resin or varnish that can be used to secure the field coil 52 and the energy coil 64.
Referring now to Figure 8, another alternative configuration for a generator module 20B is illustrated. Here, the poles 58 and 60 move away from the pole 56. This configuration reduces the exhaust flow between the pole 56 and the poles 58 and 60, improving the efficiency of the generator module 20B. Various other modifications and variations will undoubtedly occur to those skilled in the art to which the invention relates. These variations, which generally depend on the teachings through which this disclosure has advanced the art, are appropriately considered to be within the scope of this invention. This exposition, therefore, should be considered illustrative and not limiting; the scope of the invention instead is defined by the following claims.
