摘要： A river, tidal, wave or ocean current or a wind turbine for generating electricity harnesses a predetermined minimum or baseload value of hydrokinetic/wind energy from variable water/wind flow. A harnessing module may have a waterwheel or propeller and a-generator or a waterwheel or propeller alone. A harnessing module harnesses wind or water energy and may be connected to a land module of electrical and mechanical apparatus by an electrical cable. Received variable electrical input from the harnessing module is converted to a-constant electrical frequency by a connected generator feeding a grid, for example, using a Hummingbird speed converter. The received variable electrical load power may be mechanically corrected by feedback to a Kingfisher converter. An output generator to output constant frequency may use a voltage regulator, a variable voltage transformer and a control motor to provide feed forward control.

摘要： A river, tidal, wave or ocean current turbine harnesses a predetermined minimum/maximum or baseload value of hydrokinetic energy from variable water flow. A wind turbine for generating electricity may follow similar principles. A harnessing module may consist of a waterwheel and a generator or a waterwheel alone. A harnessing module harnesses wind or water renewable energy and may be preferably connected to a land module of rotational speed control electrical and mechanical apparatus through a flexible electrical cable. Received variable electrical input from harnessing module is converted to a constant electrical frequency by a connected generator feeding a grid, for example, using the Hummingbird speed converter. The received variable electrical load power may be mechanically corrected by feedback to the Kingfisher converter while feedforward control of an output generator to output constant frequency may be provided using a voltage regulator, a variable voltage transformer and a control motor. The electrical input receiving land module may process multiple inputs from any types of harnessing modules including wind and water turbines.

摘要： Three variable gear assemblies called Transgears, an electro-mechanical rotary frequency converter, and a variable torque and power generator (VT&PG) referred to herein as a variable overlap generator (VOG), may be used independently and together to provide constant frequency and voltage output power and to increase the amount of output power generated with the same input water flow, wind speed, or solar energy. Two sets of three variable spur/helical gear assemblies of sun and planetary gear sets are combined in a mechanical three variable control to form an assembly called a Hummingbird. A Hummingbird control may comprise a constant speed control motor and a constant speed generator to produce required constant frequency and voltage and be reduced in part count and complexity. In order to provide a constant control input, a constant DC voltage can be produced and a DC motor and, for example, a brush-less and commutator-less direct current generator can be used. Once a constant speed is produced, a constant frequency can be produced by a rotary frequency converter. A VOG may be used as a low torque generator and a high power-rated generator in these applications and may generate more electric power than a conventional fixed power generator (the rotor axially aligned to overlap the stator in a conventional manner) over a wider input range of renewable energy.

摘要： Three controls, three variable gear assemblies, a hatch, and a variable torque and power generator (VT&PG), may be used independently and together to provide constant frequency and voltage output power and to increase the amount of output power generated with the same input water flow or wind speed. A three variable spur/helical gear assembly of sun and planetary gear sets is a mechanical three variable control and referred to herein as a Transgear™ gear assembly, simply Transgear. A hatch wraps around a waterwheel and may control the amount of water inlet to the system by opening and closing and may be controlled by Transgears and a VT&PG. Two Transgears may comprise a constant speed motor control and produce required frequency and voltage and be reduced in part count and complexity. The VT&PG of a marine hydrokinetic or wind power generator may be used as a low torque generator and a high power-rated generator in these applications and may generate more electric power than a conventional fixed power generator (the rotor axially aligned to overlap the stator in a conventional manner) over a wider input range.

摘要： Infinitely variable motion control (IVMC) using Transgear gear assemblies provides rotary motion control without any requirement for connecting or disconnecting gear meshes or use of a clutch. A bevel, miter, ring or spur gear Transgear gear assembly may be defined as a gear assembly having three or four of variables, input, output and control, assigned in a manner so as to provide, for example, one of accumulation of inputs and direction control. A four variable Transgear gear assembly may be one of a spur gear Transgear gear assembly having an additional ring gear surrounding a set of planetary gears or a bevel gear Transgear gear assembly having a double bevel gear, an outer bevel gear and a bevel gear meshing to the outer bevel gear sleeve surrounding an inner beveled gear and comprising three orthogonal carrier shafts. Rather than two sets of three variable Transgear gear assemblies connected in series or in parallel, a four variable Transgear gear assembly may provide, for example, a direction control function with just one gear assembly with two of the four variables assignable as control variables.

摘要： A marine hydrokinetic electric power generator comprises one of a stator and a rotor which is adjustably movable through an infinite number of positions from being proximate to one another so that their magnetic fields overlap mostly to a position such that the rotor is most distant from the stator and has little overlap of magnetic field strength. Hatch and speed control may be also provided by a spur/helical gear assembly of sun and planetary gear sets referred to herein as a Transgear™ gear assembly. The variable (or fixed) power generator in operation may comprise one of a rotor and a stator being out of phase with one another by an angle, for example, the one of the rotor or the stator leading or lagging the other and the phase angle, frequency or voltage of output power to a power grid corrected responsive to inputs from the power grid and the marine hydrokinetic turbine.

摘要： A speed converter converting infinitely variable reciprocating input to uni-directional output, for example, comprising a driver, the driver comprising a variable pitch cam and a rack gear and one-way clutch bearings or Sprags and output shaft, the driver having an oblong shape may be converted to provide direction control in either of two directions and free-wheeling. The one-way clutch bearings or Sprags of a first Goldfinch speed converter are modified to comprise, concentric with the output shaft, a permanent magnet imbedded in a driven gear and direction controlling stator coils. A plurality of four (or more) electrical pulses (sine curves) may be applied to the stator coils to provide three possible outputs of desired speed: a forward output direction, a neutral or free-wheeling output and a reverse output direction. In this manner, an electro-magnetic ratchet control system may modify the speed converter to incorporate speed control, engine braking, and clockwise and counterclockwise output shaft direction control as well.
