Definitions

  • Yet another embodiment of the hydro-power generation system includes a housing, a rotor and a stator.
  • the housing includes an inlet and an outlet and forms a conduit for the passage of water therethrough.
  • the rotor is positioned within the housing and capable of rotation such the rotor is rotated by the flow of water through the housing.
  • the stator is positioned to surround the rotor such that rotation of the rotor induces the production of electricity.
  • the rotor 76 of this embodiment may be in the form of a disk that includes a plurality of permanent magnets 84.
  • the permanent magnets 84 are uniformly place in predetermined positions within the rotor 76 to operatively cooperate with the first and second stators 78, 80.
  • Each of the first and second stators 78, 80 in this embodiment may also form disks that include a plurality of coils 86.
  • the coils 86 are positioned uniformly within the first and second stators 78, 80 to operatively cooperate with the permanent magnets 84.
  • the coils 86 may be electrically connected to form one or more windings that are operable to generate electricity.
  • the number of poles and the design of the first and second stators 78, 80 are dependent on a number of factors. The factors include: the strength of the gaussian field formed by the permanent magnets 84 and the back EMF, as well as the desired RPM and the desired power output of the generator 46.
  • the rotation of the rotor 76 causes magnetic flux that is generated by the permanent magnets 84 to similarly rotate thereby producing electricity in the first and second stators 78, 80.
  • the rotor 76 and the first and second stators 78, 80 operatively cooperate to generate alternating current (AC).
  • the AC may be rectified and stabilized by the generator 46 to supply both AC and direct current (DC).
  • the permanent magnets 84 may be positioned on the first and second stators 78, 80 such that the generator 46 is operable to generate direct current (DC).
  • the generator 46 is similar to the generator 46 discussed with reference to Fig. 3.
  • the flow of water through the hydro-power generation system 12 may be controlled by the water treatment system 10.
  • the rotor housing 102 contains a rotor 112 and the stator housing 104 contains a stator 114.
  • the rotor 1 12 of this embodiment may be a twelve-pole permanent magnet rotor having six north/south pole combinations. As set
  • the salient poles 118 are formed on the stator 114 such that they circumferentially surround the rotor housing 102.
  • Each of the salient poles 118 includes a formed end that is known in the art as a pole shoe 122.
  • the pole shoes 122 are located adjacent the rotor housing 102.
  • the pole shoes 122 conduct a constant magnetic flux formed by the rotor 112 through the coils 120.
  • the coils 120 may be wire or some other similar material capable of conducting electricity and being wrapped around the salient poles 118. Although not illustrated, the coils 120 are electrically connected to form the winding.
  • the number of turns of wire used for each coil 120 is determined by the voltage and power requirements, the minimum and maximum revolutions of the rotor 112, the maximum allowable back-pressure, the required inductance and the magnetic gauss.
  • the rotor 1 12 is positioned within the rotor housing 102 coaxial with the central axis of the rotor housing 102.
  • One end of the rotor shaft 126 of the rotor 112 is inserted in a first collar 130 and the other end of the rotor shaft 126 is inserted in a second collar 132.
  • the ends of the rotor shaft 126 increase in diameter to form a solid sphere to facilitate fastening to the first collar 130 and the second collar 132.
  • the first collar 130 and the second collar 132 are formed of plastic or other similar material and create a transverse strut perpendicular to the central axis of the rotor housing 102.
  • the flowing water may be directed, for example, to act upon the rotor 112 in a predetermined way, to eliminate turbulence, to adjust pressure drop or to increase the efficiency of operation.
  • the rotor 112 of this embodiment includes a turbine rotor 164, a rotor shaft
  • the coils 184 may be made waterproof by being, for example, potted with epoxy, injection molded with rubber or plastic, ultrasonically sealed or otherwise isolated from the water by a similar waterproofing mechanism. In an alternative embodiment, the coils 184 may be located outside the housing 142 as in the embodiment previously discussed with reference to Figs. 7 and 8.
  • the back electromagnetic force (EMF) that is present is advantageously reduced.
  • EMF electromagnetic force
  • the back EMF of a permanent magnet generator is increased by flux concentrators that are formed by metal laminations in the core of the generator.
  • the flux concentrators are operable to improve the generating efficiency of the generator, but supply back EMF that must be overcome to rotate the rotor.
