ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates in general to the field of power conversion apparatus and in particular to the field of power conversion apparatus utilizing orbiting masses in conjunction with axial rotation of the masses.
2. Description of the Prior Art
There are numerous types of apparatus, which are used to convert energy, such as electricity, into a form, which is useful to do work. An electrical motor is a typical example wherein electrical energy is converted to rotational energy which can thereafter be used to turn wheels as in an automobile or to rotate machinery as with engine lathes, household appliances, grass cutters, and the like. The end use of such rotational energy is virtually limitless. With it, concrete can be made to build buildings, satellites can be built, natural resources can be mined, recycling can be accomplished, other electronic apparatus can be made, etc. Everywhere one looks, a product, a building or a process exists which has been made using rotational energy; that is, where the energy existed in a previous state e.g. electrical, chemical, nuclear, heat, wind, etc. and has been converted into rotational energy.
Accordingly, it is desirous and the need exists to develop rotational energy having improved efficiency, produces large amounts of power and is cost effective. The present invention fulfills this need and accomplishes these objectives.
SUMMARY OF THE INVENTION
The present invention comprises apparatus that in a preferred embodiment, converts electrical energy into rotational energy by uniquely using small electrical motors to generate orbital rotation which, in turn, utilizes the mass of the electrical motors to produce high-power output. In one embodiment, a plurality of electrical motors are equidistantly arranged about a diameter of a rotatable plate, the rotating shaft of each of the motors includes a pulley which is connected by a belt to a stationary disc or cylinder located at the center of the rotatable plate. The rotatable plate is connected at its center to a shaft or axle.
In operation, electrical energy is input to the electrical motors which causes rotation of the motor shafts. Because the other end of the belts are connected around the stationary cylinder, rotation of the motor shafts causes rotation of the rotatable plate to which the motors are attached. The speed of rotation of the rotatable plate is directly dependent upon the ratio of the diameter of the fixed cylinder to the diameter of the pulley attached to the motor shafts. The same rotational speed of the rotatable plates occurs regardless of the distance between the center of the motors to the center of the fixed cylinder; but, the further the motors are from the center of the fixed cylinder, the greater the amount of centrifugal force is created. This geometric advantage is utilized in the present invention to increase the torque and or power produced by the center shaft of the inventive apparatus.
