An electronically commutated brushless motor including a housing for accurately angularly aligning a position sensor relative to a position of a stator. The housing includes an integrally formed bridge for precisely situating the position sensor within the bridge, and a plurality of integrally formed locating ribs formed on an internal surface of a circumferential wall portion of the housing for precisely angularly situating the stator within the housing. Since the locating ribs and the bridge are all integrally formed on the housing, this eliminates the possibility of angular misalignment of the position sensor relative the stator during assembly of the motor.

The reference voltage is higher than a voltage required to trigger the logic gates and a voltage required to drive the load. This ensures that the load is driven adequately over a wide range of load currents and capacitances. By setting the reference voltage between the voltage required to drive the load and the supply voltage, the pulse width is not excessive. portion of said base assembly and pivoting of said upper portion with respect to said junction portion when said solar assembly is to be directed towards the sun and said turbine assembly is to be directed into the wind. 3. The turbine generator apparatus as set forth in claim 1, further comprising: said solar assembly comprising a plate portion, said plate portion being coupled to said upper portion of said base assembly, said solar assembly comprising a plurality of solar cells, each of said solar cells being positioned on an upper surface of said plate portion, each of said solar cells being adapted for converting solar radiation into electricity, each of said solar cells being operationally coupled to said power storage assembly such that said power storage assembly stores electricity from each said solar cells. 4. The turbine generator apparatus as set forth in claim 1, further comprising: said turbine assembly comprising a head assembly and a stanchion, said stanchion being coupled to said upper portion of said base assembly such that said stanchion upwardly extends from said solar assembly, said head assembly being rotatably coupled to said stanchion opposite said base assembly, said head assembly being adapted for being rotated with respect to said stanchion of said turbine assembly when said head assembly is directed into the wind. 5. The turbine generator apparatus as set forth in claim 4, further comprising: said turbine assembly having a shroud sleeve, said shroud sleeve being upwardly extending from said solar assembly, said shroud sleeve having a lumen such that said stanchion is extending through said lumen of said shroud sleeve, said stanchion being retractable with said shroud sleeve such that said head assembly is retractable into said lumen of shroud sleeve for protecting said head assembly from adverse weather. 6. The turbine generator apparatus as set forth in claim 4, further comprising: said head assembly comprising a pair a blades, each of said blades being coupled to a shaft, one of said blades diametrically extending away from the other of said blades, each of said blades having an airfoil cross-section such that the wind striking said blades forces said blades into rotary motion thereby rotating said shaft, said shaft being operationally coupled to a generator. 7. The turbine generator apparatus as set forth in claim 6, further comprising: said blades comprising a first blade and a second blade, said first blade being coupled to said shaft, said second blade having a collar, said collar having an aperture such that said aperture of said collar being for receiving said shaft, said collar having a cut out, said cut out receiving said first blade when said second blade is positioned diametrically to said first blade such that said blades are balanced when said blades are rotated by the wind, said collar of said second blade permitting rotation of said second blade adjacent to said first blade for facilitating storage of said head assembly. 8. The turbine generator apparatus as set forth in claim 4, further comprising: said head assembly of said turbine assembly having a plurality of vanes, each of said vanes extending between a pair of annular rings, each of said annular rings being coupled to said stanchion such that said vanes are spaced around said stanchion, each of said vanes being adapted for catching the wind for rotating said annular rings such that rotation of said annular rings rotates said stanchion, said stanchion being coupled to a generator, said generator being adapted for producing electricity when the wind strikes said blades and rotates said shaft. 9. The turbine generator apparatus as set forth in claim 8, further comprising: each of said vanes comprising a flexible material, said flexible material of each of said vanes extending parallel to an longitudinal axis of said stanchion such that said flexible material of said vanes is adapted for flexing a
